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.

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: 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.
• If the motor run capacitor was not installed by ebm-papst, check whether the information on the motor run capacitor matches the information on the nameplate.
• 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 60335: Compliance with the resistance specifications according to EN 60335 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.

4.2.2 Voltage control

NOTE: Current overshoots may occur if speed control is implemented by transformers or electronic voltage regulators (e.g. phase control). Depending on the type of installation of the device, noise and vibration may also occur in the case of phase control. Vibration can lead to bearing damage and thus premature failure. Heating-up of the motor when using voltage control must be checked by the customer following installation in the end device.

4.2.3 Variable frequency drive

Please use a variable frequency drive only after consultation with ebm-papst.

• For operation with variable frequency drives, install sinusoidal filters that work on all poles (phase-phase and phase-ground) between the drive and the motor.
• During operation with variable frequency drives, an all-pole sine filter protects the motor against high-voltage transients that can destroy the coil insulation system, and against harmful bearing currents.
• Heating-up of the motor when using a variable frequency drive must be checked by the customer following installation in the end device.

4.3 Connecting the cables

The device has external leads.

• First connect the "PE" (protective earth).
• Connect the cables according to your application. When doing so, observe Chapter 4.4 Connection diagram.

4.3.1 Cable routing

Water must be prevented from reaching the cable exit 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.

Fans installed upright

• Before switching on, check the device for visible external damage and make sure the protective devices are functional.
• Check the fan's air flow paths for foreign matter and remove any foreign matter found.
• Apply the nominal supply voltage.

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.

4.7 Switching off the device

• Disconnect the device from the power supply at the supply line's main switch.
• When disconnecting, be sure to disconnect the ground connection last.
