Before You Begin
Read and take note of these instructions before you begin any procedure with this drive.
DANGER: DANGEROUS VOLTAGE
- Read and understand this entire installation manual before installing and operating the ATV71 variable speed drive. Installation, settings, and repairs must be undertaken by qualified personnel.
- The user is responsible for compliance with all international and national electrical standards in force concerning protective grounding of all equipment.
- Many parts of this variable speed drive, including the printed circuit boards, operate at the line voltage. DO NOT TOUCH THEM. Only use tools equipped with electrical insulation.
- Do not touch unshielded components or screws on the terminals if the device is switched on.
- Do not short-circuit the PA/+ and PC/- terminals or the DC bus capacitors.
- Fit and close all the covers before switching on the drive.
- Before any servicing or repair work on the variable speed drive: Disconnect the power supply, place a label stating "DO NOT SWITCH ON" on the circuit-breaker or isolator, and lock the circuit-breaker or isolator in the open position.
- Before working on the speed drive, disconnect the power supply, including the external control circuit supply if it is used. WAIT FOR 15 MINUTES to allow the DC bus capacitors to discharge. Then follow the procedure for measuring the DC bus voltage on page 15 to check whether the DC voltage is below 45 V. The LED on the variable speed drive is not an accurate indicator of lack of voltage on the DC bus.
Electric shock will cause death or serious injury.
CAUTION
- If the drive is not switched on for a long period, the performance of its electrolytic capacitors will be reduced.
- If it is stopped for a prolonged period, switch the drive on every two years for at least 5 hours to restore the performance of the capacitors, then check its operation.
- It is recommended that the drive is not connected directly to the line voltage. The voltage should be increased gradually using an alternostat.
Failure to observe this precaution may result in material damage.

Handling on Installation
ALTIVAR 71 drives up to ratings ATV71HD15M3X and ATV71HD18N4 can be removed from their packaging and installed without a handling device. A hoist must be used with higher ratings; for this reason they are fitted with handling "lugs". The precautions described below must be observed.
Precautions
Read and take note of the instructions in the "programming manual".
CAUTION: INCOMPATIBLE LINE VOLTAGE
Before switching on and configuring the drive, check that the line voltage is compatible with the drive supply voltage. The drive may be damaged if the line voltage is not compatible. Failure to observe this precaution may result in material damage.
DANGER: UNEXPECTED OPERATION OF THE DEVICE
- Before switching on and configuring the Altivar 71, check that the PWR (POWER REMOVAL) input is deactivated (at state 0) in order to prevent unexpected restarting.
- Before switching on or on exiting the configuration menus, check that the inputs assigned to the run command are deactivated (at state 0) since they can cause the motor to start immediately.
Failure to observe these precautions will result in death or serious injury.
If the safety of personnel requires the prohibition of unwanted or unexpected restarting, electronic locking is performed by the Altivar 71's Power Removal function. This function requires the use of connection diagrams conforming to category 3 of standard EN 954-1 and safety integrity level 2 according to IEC/EN 61508. The Power Removal function takes priority over any run command.

Notes for tables:
- (1) Power ratings and currents are given for an ambient temperature of 50°C at the factory-set switching frequency, used in continuous operation (switching frequency factory setting 4 kHz for ATV71H 037M3 to D15M3X drives, and 2.5 kHz for ATV71H D18M3X to D45M3X drives). Above this factory setting, the drive will reduce the switching frequency of its own accord in the event of excessive temperature rise. For continuous operation above the factory setting, derating must be applied to the drive nominal current in accordance with the curves on page 11.
- (2) Current on a line supply with the "Max. prospective line Isc" indicated and for a drive without any external options.
- (3) Peak current on power-up for the max. voltage (240 V +10% or 480 V +10%).
- (4) ATV71H 037M3 to D15M3X drives are available with or without a graphic display terminal. References of drives without a graphic display terminal have the letter Z added at the end, e.g.: ATV71H075M3Z. This option is not available for drives which operate in difficult environmental conditions (5).
- (5) Drives with the S337 or 337 extension are designed for use in difficult environmental conditions (class 3C2 in accordance with IEC 721-3-3). They are supplied with a graphic display terminal.
- (6) A line choke must be used (please refer to the catalog).
- Inhibit the fault indicating the loss of a line phase (IPL) so that ATV71H 075M3 to U75M3 drives can operate on a single phase supply (see programming manual). If this fault is set to its factory configuration, the drive will stay locked in fault mode.

Dust and Damp Proof Flush Mounting
This mounting is used to reduce the power dissipated in the enclosure by locating the power section outside the enclosure. This requires the use of the dust and damp proof flush mounting kit VW3A9501...516 (please refer to the catalog). The degree of protection for the drive mounted in this way becomes IP54. To fit the kit to the drive, please refer to the manual supplied with the kit.

Fitting the Graphic Display Terminal
Drives, whose references end in the letter Z, are supplied without a graphic display terminal (VW3A1101). This can be ordered separately. It is fitted to the drive as shown below.
[Diagram showing the fitting of the graphic display terminal onto the drive]
The graphic display terminal can be connected or disconnected with the power on. Before disconnecting it, drive control via the display terminal must be disabled (refer to the programming manual).
Position of the Charging LED
Before working on the drive, switch it off, wait until the red capacitor charging LED has gone out, then measure the DC bus voltage.

Procedure for Measuring the DC Voltage
DANGER: DANGEROUS VOLTAGE
Read and make sure you understand the precautions on page 4 before you begin this procedure. Failure to observe this precaution will result in death or serious injury.
The DC bus voltage can exceed 1000 V. Use a suitable measuring instrument when undertaking this procedure. To measure the DC bus voltage:
- Disconnect the drive power supply.
- Wait 15 minutes to allow the DC bus capacitors to discharge.
- Measure the voltage of the DC bus between the PA/+ and PC/- terminals to check whether the voltage is less than 45 V. Refer to page 22 for the layout of the power terminals.
- If the DC bus capacitors have not discharged completely, contact your local Schneider Electric agent (do not repair or operate the drive).
Fitting the Option Cards
These should ideally be fitted once the drive is fixed in place and before wiring it. Check that the red capacitor charging LED has gone out. Measure the DC bus voltage in accordance with the procedure indicated on page 15. The option cards are fitted under the drive control front panel. If the drive has a graphic display terminal, remove it, then remove the control front panel as indicated below.
Removing the Control Front Panel
[Diagram showing steps 1, 2, 3 for removing the front panel]
1. Using a screwdriver, press down on the catch and pull to release the left-hand part of the control front panel.
2. Do the same on the right-hand side.
3. Pivot the control front panel and remove it.
Fitting an Encoder Interface Card
There is a special slot on the drive for adding an encoder interface card.
[Diagram showing fitting an encoder interface card]
If an I/O or communication option card or a "Controller Inside" programmable card has already been fitted, remove it so you can access the slot for the encoder interface card.
Fitting an I/O Extension Card, a Communication Card or a "Controller Inside" Programmable Card
[Diagram showing steps 5, 6, 7 for fitting option cards]
1, 2 and 3: Remove the control front panel (see previous page).
4: Fit an encoder interface card (if used) (see previous page).
5: Position the option card on the clasps.
6: Then pivot it until it clicks into place.
7: Replace the control front panel over the option card (same procedure as for fitting the option card, see 5 and 6).

Wiring Recommendations
Power
The drive must be connected to the protective ground. To comply with current regulations concerning high leakage currents (over 3.5 mA), use at least a 10 mm² protective conductor or 2 protective conductors with the same cross-section as the power supply conductors.
DANGER: DANGEROUS VOLTAGE
Connect the drive to the protective ground using the grounding connection point provided, as shown in the diagram. The drive fixing points must be connected to the protective ground before switching on. Failure to observe these precautions will result in death or serious injury.
[Diagram showing grounding connections for variable speed drives]
Check whether the resistance to the protective ground is one ohm or less. Connect a number of variable speed drives to the protective ground, as shown in the diagram (see left). Do not lay protective grounding cables in a loop or in series.
WARNING: UNSUITABLE WIRING CONNECTIONS
- The ATV71 will be damaged if the line voltage is applied to the output terminals (U/T1,V/T2,W/T3).
- Check the electrical connections before switching on the ATV71.
- If you are replacing another variable speed drive, check that all the electrical connections to the ATV71 conform to all the wiring instructions in this manual.
Failure to observe this precaution will result in death or serious injury.
When upstream protection by means of a "residual current device" is required by the installation standards, a type A device should be used for single phase drives and type B for 3-phase drives. Choose a suitable model incorporating:
- HF current filtering.
- A time delay which prevents tripping caused by the load from stray capacitance on power-up. The time delay is not possible for 30 mA devices. In this case, choose devices with immunity against accidental tripping, for example "residual current devices" with reinforced immunity from the s.i range (Merlin Gerin brand).
If the installation includes several drives, provide one "residual current device" per drive.
WARNING: INADEQUATE PROTECTION AGAINST OVERCURRENTS
- Devices for protecting against overcurrents must be matched to the drive correctly.
- The Canadian electricity code or National Electrical code (US) insist on protection of branch circuits. Use the fuses recommended on the drive rating plate in order to obtain the nominal short-circuit current.
- Do not connect the drive to a line supply whose short-circuit capacity exceeds the maximum prospective short-circuit current indicated on the drive rating plate.
Failure to observe this precaution may result in death or serious injury.
Control
Keep the control circuits away from the power circuits. For control and speed reference circuits, we recommend using shielded twisted cables with a pitch of between 25 and 50 mm (0.98 and 1.97 in.) and connecting the shielding to ground at each end.
If using conduit, do not lay the motor, power supply and control cables in the same conduit. Keep the metal conduit containing the power supply cables at least 8 cm (3 in.) away from the metal conduit containing the control cables. Keep the non-metal conduits or cable ducts containing the power supply cables at least 31 cm (12 in.) away from the metal conduits containing the control cables. The power supply and control cables must always cross over at right-angles.

Inhibit the fault indicating the loss of a line phase (IPL) so that ATV71H 075M3 to U75M3 drives can operate on a single phase supply (see programming manual). If this fault is set to its factory configuration, the drive will stay locked in fault mode.
Note: Fit interference suppressors to all inductive circuits near the drive or coupled to the same circuit (relays, contactors, solenoid valves, etc).

Connection Diagrams Conforming to Standards EN 954-1 Category 3 and IEC/EN 61508 Capacity SIL2, Stopping Category 0 (Standard IEC/EN 60204-1)
This connection diagram is suitable for use with machines with a short freewheel stop time (with low inertia or high resistive torque). When the stop request is activated, the motor power supply is switched off immediately and it stops in accordance with category 0 of standard IEC/EN 60204-1.
This diagram must be used for hoisting applications if a mechanical brake is controlled by the ATV71. A contact on the Preventa XPS AC module must be inserted in the brake control circuit to engage it safely when the Power Removal safety function is activated.
[Diagram showing safety connection with XPS AC module, including motor, drive, braking resistor, and control signals like S1, S2, S3, S4, ESC, Y1, Y2, K1, K2, etc.]
(1) Line choke (if used).
(2) It is essential to connect the shielding on the cable connected to the Power Removal input to ground.
Notes on Safety Standards:
- Standard EN 954-1 category 3 requires the use of a stop button with double contact (S1).
- S1 is used to activate the Power Removal safety function.
- S2 and S3 are the optional start and stop controls.
- S4 is used to initialize the Preventa module when switching on or after an emergency stop. ESC enables the use of other initialization conditions for the module.
- One Preventa module can be used for the Power Removal safety function on several ATV71 drives.
- A logic input on the Preventa module can be used to indicate safely that the drive is operating in safe conditions.
Note: For preventive maintenance, the Power Removal function must be activated at least once a year. The drive power supply must be switched off and then on again before carrying out this preventive maintenance. The drive logic output signals cannot be considered as safety-type signals. Fit interference suppressors to all inductive circuits near the drive or coupled to the same circuit (relays, contactors, solenoid valves, etc).

Connection Diagram Conforming to Standards EN 954-1 Category 3 and IEC/EN 61508 Capacity SIL2, Stopping Category 1 (Standard IEC/EN 60204-1)
This connection diagram is suitable for use with machines with a long freewheel stop time (machines with high inertia or low resistive torque). This diagram must not be used for lifting applications. When the stop request is activated, deceleration of the motor, controlled by the drive, is requested first. Then, after a time delay corresponding to the deceleration time, the Power Removal safety function is activated.
Example: 2-wire control, LI1 assigned to forward, LI2 assigned to reverse.
[Diagram showing safety connection for long freewheel stop time, including XPS AT module, motor, drive, braking resistor, and control signals]
(1) In this example, the logic inputs LIp are wired as "Source" but can be wired as "Int Sink" or "Ext Sink".
(2) Line choke (if used).
(3) It is essential to connect the shielding on the cable connected to the Power Removal input to ground.
Notes on Safety Standards:
- Standard EN 954-1 category 3 requires the use of a stop button with double contact (S1).
- S1 is used to activate the Power Removal safety function.
- S2 and S3 are the optional start and stop controls.
- S4 is used to initialize the Preventa module when switching on or after an emergency stop. ESC enables the use of other initialization conditions for the module.
- One Preventa module can be used for the Power Removal safety function on several ATV71 drives. In this case the time delay must be set to the longest stopping time.
- A logic input on the Preventa module can be used to indicate safely that the drive is operating in safe conditions.
Note: For preventive maintenance, the Power Removal function must be activated at least once a year. The drive power supply must be switched off and then on again before carrying out this preventive maintenance. The drive logic output signals cannot be considered as safety-type signals.

Control Connection Diagrams
Control Card Connection Diagram
[Diagram showing the control card connections, including reference potentiometer and logic input switch]
Logic Input Switch (SW1)
The logic input switch (SW1) is used to adapt the operation of the logic inputs to the technology of the programmable controller outputs.
- Set the switch to Source (factory setting) if using PLC outputs with PNP transistors.
- Set the switch to Int Sink or Ext Sink if using PLC outputs with NPN transistors.
SW1 switch set to "Source" position: [Diagram]
SW1 switch set to "Source" position and use of an external power supply for the LIs: [Diagram]
SW1 switch set to "Int Sink" position: [Diagram]
SW1 switch set to "Ext Sink" position: [Diagram]
WARNING: Accidental Starting of the Drive
When the SW1 switch is set to "Int Sink" or "Ext Sink", the common must never be connected to ground or the protective ground, as there is then a risk of accidental starting on the first insulation fault. Failure to observe this precaution may result in death or serious injury.

SW2 Switch
The LI6 logic input switch (SW2) makes it possible to use the LI6 input: either as a logic input by setting the switch to LI (factory setting) or for motor protection via PTC probes by setting the switch to PTC.
[Diagram showing SW2 switch configuration for LI and PTC]

WARNING: Accidental Starting of the Drive
When the SW3 or SW4 switches are set to "Int Sink" or "Ext Sink", the common must never be connected to ground or the protective ground, as there is then a risk of accidental starting on the first insulation fault. Failure to observe this precaution may result in death or serious injury.
Connection of Several Drives in Parallel on the DC Bus
Connection in parallel on the DC bus is recommended in applications for which full motor power must be guaranteed. Each drive uses its own charging circuit.
[Diagram showing connection of several drives in parallel on the DC bus, with fuses F1, F2, F3]
Drives 1, 2 and 3 must not be more than one size apart when they are connected in this way. F1, F2, F3: fast-acting fuses for protection on the DC bus side.
Operation on an IT System
IT system: Isolated or impedance grounded neutral. Use a permanent insulation monitor compatible with non-linear loads: a Merlin Gerin type XM200, for example.
Altivar 71 drives feature built-in RFI filters. These filters can be isolated from ground for operation on an IT system as follows: Remove the jumper located to the left of the power terminals.
Normal (filter connected) / IT system (filter disconnected) [Diagram showing jumper removal for IT system operation]
CAUTION
When the filters are disconnected, the drive switching frequency must not exceed 4 kHz. Refer to the programming manual for the corresponding parameter setting. Failure to observe this precaution may result in material damage.
Electromagnetic Compatibility, Wiring
Electromagnetic Compatibility
Principle
- Grounds between drive, motor and cable shielding must have "high frequency" equipotentiality.
- Use of shielded cables with shielding connected to ground at both ends for the motor cables, braking resistor (if used) and control-signaling wiring. Conduits or metal ducting can be used for part of the shielding length provided that there is no break in continuity.
- Ensure maximum separation between the power supply cable (line supply) and the motor cable.

ATV71H 037M3 to D15M3X and ATV71H 075N4 to D18N4
- Fix and ground the shielding of cables 4 and 5 as close as possible to the drive: Strip the shielding. Use stainless metal cable clamps on the parts from which the shielding has been stripped, to attach them to the plate 2. The shielding must be clamped tightly enough to the metal plate to ensure correct contact.
- Fit the control EMC plate 11 on the sheet steel grounded plate 2, as shown in the drawing.
- Fix and ground the shielding of cables 7, 12 and 13 as close as possible to the drive: Strip the shielding. Use stainless metal cable clamps on the parts from which the shielding has been stripped, to attach them to the control EMC flange 9. The shielding must be clamped tightly enough to the metal plate to ensure correct contact.
[Diagram showing installation details for EMC compatibility for smaller drive models, with numbered components and connections]
Key to diagram:
- 1 Altivar 71
- 2 Sheet steel grounded plate supplied with the drive.
- 3 Tapped holes for fixing the control EMC plate.
- 4 Shielded cable for motor connection, with shielding connected to ground at both ends. The shielding must be continuous and intermediate terminals must be in EMC shielded metal boxes.
- 5 Shielded cable for connecting the braking resistor (if fitted). The shielding must be continuous and intermediate terminals must be in EMC shielded metal boxes.
- 6 Non-shielded wires for relay contact output.
- 7 Shielded cables for connecting the Power Removal safety function input. The shielding must be continuous and intermediate terminals must be in EMC shielded metal boxes.
- 8 Metal clamps.
- 9 Connection to the protective ground.
- 10 Non-shielded power supply wires or cable.
- 11 Control EMC plate.
- 12 Shielded cables for connecting the control-signaling wiring. For applications requiring several conductors, use cables with a small cross-section (0.5 mm²).
- 13 Shielded cables for connecting the encoder. The shielding must be continuous and intermediate terminals must be in EMC shielded metal boxes.
Note:
- If using an additional input filter, it should be fitted under the drive and connected directly to the line supply via an unshielded cable. Link 10 on the drive is then via the filter output cable.
- The HF equipotential ground connection between the drive, motor and cable shielding does not remove the need to connect the PG protective conductors (green-yellow) to the appropriate terminals on each unit.
