Checking Suitability of the drive
4.1. Matching the drive to the Intended Power Supply
Check the drive rating label to ensure it matches the intended power supply, the label shows the rated supply voltage and if the drive is suitable for single or 3-phase supply.
For three phase supply models, a maximum of 3% imbalance is allowed between phases.
If using an IT Supply network, or any power supply type where the phase to earth voltage may exceed the phase-to-phase voltage (such as ungrounded supplies), the internal EMC filter and surge protection must be disconnected before connecting the supply.
A fixed installation is required according to IEC61800-5-1 with a suitable disconnecting device installed between the drive and the main Power Source. The disconnecting device must conform to the local safety code / regulations (e.g. within Europe, EN60204-1, Safety of machinery).
Electrical Installation
This manual is intended as a guide for proper installation. Inverter Drives Ltd cannot assume responsibility for the compliance or the non-compliance to any code, national, local or otherwise, for the proper installation of this drive or associated equipment. A hazard of personal injury and/or equipment damage exists if codes are ignored during installation.
This drive contains high voltage capacitors that take time to discharge after removal of the main supply. Before working on the drive, ensure isolation of the main supply from line inputs. Wait ten (10) minutes for the capacitors to discharge to safe voltage
levels. Failure to observe this precaution could result in severe bodily injury or loss of life.
Only qualified electrical personnel familiar with the construction and operation of this equipment and the hazards involved should install, adjust, operate, or service this equipment. Read and understand this manual and other applicable manuals in their entirety before proceeding. Failure to observe this precaution could result in severe bodily injury or loss of life.

• Check Supply Voltage does not exceed drive Voltage rating. • Check the number of supply phases is compatible with the drive. • If the power supply has a low supply impedance /high short circuit current a Line reactor/Isolation transformer maybe required. • For generator Bourne power supplies please contact your IDL Authorized Distributor for further guidance. |
|||||||||||||||||||||||
| • Ensure there is at least 30 seconds between each power-on. | ||||||||||||||||||||||||
| • Install suitably rated fuses/Circuit breakers • If an earth leakage detection device is used (e. g. ELCB/RCD), a type B trip characteristic which is suitable for protecting equipment with a DC component should be used, 1 device for multiple drives should be avoided. |
||||||||||||||||||||||||
| Install Line reactor as close to the drive as possible and under the following conditions: • If phase-phase imbalance is >3% (3Ø drives). • To reduce Inrush current. • If power supply has a low supply impedance/high short circuit current. • If power supply is prone to dips or brown-outs. • If power supply is via a bus-bar and sliding contacts system. • Reduction in mains Harmonic emission. |
||||||||||||||||||||||||
| • Install External EMC filter if the motor cable length exceeds the Electromagnetic interference reduction capability of the internal filter • Do Not Use EMC filters on IT (Ungrounded) or a corner grounded TN power supply systems. |

5.3.1. Brake resistor Connections
The drive has an internal brake transistor fitted as standard and is enabled automatically when the regenerative energy from the load raises the drives internal DC bus to 390Vdc for the single and three phase 230V drives and 780Vdc for the 3 phase 400V drive.
The brake resistor must be connected between the +DC and BR Terminals of the drive as shown in the images below, failure to do so can result in damage to the drive/Brake resistor.

Out of Box/Default functions shown for control Inputs and Outputs, functions can be changed if required
6.2. Step 2- Pre-Power Checks.
| Action/Checks | Additional Information |
 Do Not Apply Electrical Power Yet! |
Check that all safety circuits/safety chains are in the correct state, failure to do so could result in damage to the equipment and possible injury or death. Check that the intended voltage source matches that of the drive voltage rating. Check that any unexpected movement in the motor will not result in damage to equipment / safety risk to persons. Check that the elevator controller will not give a start signal to the drive when Electrical power is applied. Ideally the Lift car should be balanced (i.e. with brakes off the lift car should not naturally move) and with enough shaft headroom in order to prevent reaching end stops during initial test travels. |
| Check all necessary electrical connections. | Check Electrical Supply cables are connected to the Input power terminals of the drive. Check Motor Cables are connected to the drive U, V, W terminals (If cables have identification markers connect correct phase sequence). Check Brake resistor is connected to the “DC+” and “BR” terminals of the drive. Check correct control connections are made between the Elevator control panel and the drive Check correct encoder module (optional) has been installed and the correct connections are made between the drive and the Encoder. |

Provide a run-direction command to terminal 2 and run at low speed for a short travel e.g. levelling/10% of motor rated speed, you can Use P8-01 (Maximum speed limit) to limit the motor speed and return back to normal value afterwards. Check that the value shown in P0-18 is positive in the Up direction and Negative in the down direction, if it is not then set P11-10 to 1. Check that the value in P0-15 and P0-19 match in sign. |
If the drive shows  when a run-direction command is given ensure that the Safe Torque off inputs are made. |

| Check for Suitable travel headroom | Ideally the Lift car should be balanced (i.e. with brakes off, the lift car should not naturally move) and with enough shaft headroom in order to prevent reaching end stops during initial test travels. |
| Run the elevator at reduced speed. | □ Provide a speed reference to the drive. Normally inspection speed is used. If P1-02 is at default value (P1-02=1) then inspection speed is defined in parameterP8-08, in this case inspection speed is selected when DI6 is high. Alternatively use the maximum speed parameter P8-01 to clamp the speed to a lower value. |
□ Provide a run-direction command to the drive. |
|
If the drive shows when a run-direction command is given, ensure that the Safe Torque off inputs are closed. |
