CAUTION: Heavy load when unpacking device. Risk of physical injury, such as back injuries.

• Two people should work together to remove the device from its packaging.

NOTE: Damage to the device from vibration. Bearing damage, shorter service life.

• The fan must not be subjected to force or excessive vibration from sections of the installation.
• If the fan is connected to air ducts, the connection should be isolated from vibration, e.g. using compensators or similar elements.
• Ensure stress-free attachment of the fan to the substructure.
• Check the device for transport damage. Damaged devices are not to be installed.
• Install the undamaged device in accordance with your application.

CAUTION: Possible damage to the device. If the device slips during installation, serious damage can result.

• Ensure that the device is securely positioned at its place of installation until all fastening screws have been tightened.
• The fan must not be strained on fastening.

4.2 Electrical Connection

DANGER: Voltage on the device. Electric shock.

• Always connect a protective earth first.
• Check the protective earth.

DANGER: Faulty insulation. Risk of fatal injury from electric shock.

• Use only cables that meet the specified installation regulations for voltage, current, insulation material, capacity, etc.
• Route cables so that they cannot be touched by any rotating parts.

DANGER: Electrical charge (>50 µC) between phase conductor and protective earth connection after switching off supply with multiple devices connected in parallel. Electric shock, risk of injury.

• Ensure sufficient protection against accidental contact.
• Before working on the electrical hookup, short the supply and PE connections.

CAUTION: Voltage. The fan is a built-in component and has no disconnecting switch.

• Only connect the fan to circuits that can be switched off with an all-pole disconnection switch.
• When working on the fan, secure the system/machine in which the fan is installed so as to prevent it from being switched back on.

NOTE: Device malfunctions possible.

• Route the device's control lines separately from the supply line.
• Maintain the greatest possible clearance. Recommendation: clearance > 10 cm (separate cable routing).

NOTE: Water ingress into wires or cables. Water ingress at the customer end of the cable can damage the device.

• Make sure the end of the cable is connected in a dry environment.
• Only connect the device to circuits that can be switched off with an all-pole disconnection switch.

4.2.1 Requirements

• Check whether the information on the nameplate matches the connection data.
• Before connecting the device, make sure the power supply matches the device voltage.
• Only use cables designed for the current level indicated on the nameplate. For determining the cross-section, note the sizing criteria according to EN 61800-5-1. The protective earth must have a cross-section equal to or greater than that of the phase conductor.
• We recommend the use of 105 °C cables. Ensure that the minimum cable cross-section is at least AWG 26 / 0.13 mm².

Protective earth contact resistance according to EN 61800-5-1

Compliance with the resistance specifications according to EN 61800-5-1 for the protective earth connection circuit must be verified in the end application. Depending on the installation situation, it may be necessary to connect an additional protective earth conductor by way of the extra protective earth terminal provided on the device. The protective earth terminal is located on the housing and provided with a protective earth symbol and a hole.

4.2.2 Supply Connection and Fuses

Assignment of supply cable cross-sections and their required fuses (line protection only, no equipment protection).

* AWG = American Wire Gauge

4.2.3 Reactive Currents

Because of the EMC filter integrated for compliance with EMC limits (interference emission and immunity to interference), reactive currents can be measured in the supply line even when the motor is at a standstill and the line voltage is switched on.

• The values are typically in the range < 500 mA.
• At the same time, the effective power in this operating state (operational readiness) is typically < 6 W.

4.2.4 Residual Current Circuit Breaker (RCCB)

If the use of a residual current device (RCD) is required in your installation, only AC/DC-sensitive residual current devices (type B or B+) are permissible. As with variable frequency drives, residual current devices cannot provide personal safety while operating the device. When the device power supply is switched on, pulsed charging currents from the capacitors in the integrated EMC filter can lead to the instant tripping of residual current devices. We recommend the use of residual current circuit breakers (RCCB) with a trip threshold of 300 mA and delayed tripping (super-resistant, characteristic K).

4.2.5 Leakage Current

For asymmetrical power systems or if a phase fails, the leakage current can increase to a multiple of the nominal value.

4.2.6 Locked-Rotor Protection

Due to the locked-rotor protection, the starting current (LRA) is equal to or less than the nominal current (FLA).

4.3 Connection in Terminal Box

4.3.1 Preparing Cables for Connection

Only strip the cable as far as necessary, ensuring that the cable gland is sealed and there is no strain on the connections. For tightening torques, see Chapter 3.1 Product drawing.

NOTE: Tightness and strain relief are dependent on the cable used. This must be checked by the user.

Diagram showing recommended stripped lengths inside the terminal box for supply line (1) and control/relay line (2).

NOTE: Crimping and pressing forms of the wire-end ferrules. For flexible control and relay cables, from a cable cross-section of 1.0 mm², a trapezoid crimp is required to ensure correct installation on the connector.

Diagram showing trapezoid crimp dimensions (max. 2.2 mm and max. 1.2 mm).

4.3.2 Terminal Connection Data

NOTE: The cable and cable cross-section must be selected taking into account the max. starting current of the drive and the type of cable routing (see Chapter 4.2.2 Supply connection and fuses).

4.3.3 Connect Cables to Terminals

WARNING: Live terminals and connections even with device switched off. Electric shock.

• Wait five minutes after disconnecting the voltage at all poles before opening the device.
• Open the terminal box.
• Remove the cap from the cable gland.
• Only remove caps where cables are fed in.

Diagram showing installation of connectors in the terminal box. Ensure connectors engage properly.

• Depending on the cable diameter, the seals included in the terminal box must be inserted into the cable gland if necessary.
• Route the cable(s) (not included in the scope of delivery) into the terminal box.
• Ensure separate routing of the supply cable(s) and the cables for status contact and control interface. Depending on the requirements for the end device, the physical separation of these cables in the terminal box may be mandatory. Use the partitions inside the terminal box as an aid to routing for this purpose.
• First connect the protective earth "PE". Tightening torque 3.5 ±0.4 Nm.
• Connect the cables to the corresponding terminals. Use a screwdriver to do so. When connecting, make sure the wires do not splay out. Insert the strands until they meet with resistance.

Diagram showing connection of cables at terminals. Ensure no tensile stress and proper strain relief.

• There must not be any tensile stress between the terminal and the cable gland. The cable must be provided with strain relief.
• The cable glands must be tight.
• Fit the terminal box cover, making sure that the sealing surfaces are clean.
• Screw in the four screws (for tightening torque, see Chapter 3.1 Product drawing).

4.3.4 Cable Routing

Water must be prevented from reaching the cable gland along the cable.

NOTE: Damage caused by moisture penetration. Moisture can penetrate into the terminal box if water is constantly present at the cable glands.

• To prevent the constant accumulation of water at the cable glands, the cable should be routed in a U-shaped loop wherever possible.
• If this is not possible, a drip edge can be produced by fitting a cable tie directly in front of the cable gland for example.

When routing the cable, make sure that the cable glands are located at the bottom. The cables must always be routed downward.

• Check the fan's air flow paths for foreign matter and remove any foreign matter found.
• Apply the nominal supply voltage.
• Start the device by changing the input signal.

NOTE: Damage to the device from vibration. Bearing damage, shorter service life.

• Low-vibration operation of the fan must be ensured over the entire speed control range.
• Severe vibration can arise for instance from inexpert handling, transportation damage and resultant imbalance or be caused by component or structural resonance.
• Speed ranges with excessively high vibration levels and possibly resonant frequencies must be determined in the course of fan commissioning.
• Either run through the resonant range as quickly as possible with speed control or find another remedy.
• Operation with excessively high vibration levels can lead to premature failure.
• The maximum permissible vibration severity must not exceed 3.5 mm/s and should be checked at intervals of 6 months. It is to be determined at the motor mount at the motor support plate at least in axial direction and transversely to this. Measurement of the vibration in all three axes is recommended and should be performed over the entire speed range in order to obtain a complete picture of the vibrations occurring in the application, see Chapter 6. Maintenance, malfunctions, possible causes and remedies.
