Translation of the original operating instructions

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
Water ingress into wires or cables

Water ingresses at the customer cable end and can damage the
device.
→ Make sure the end of the cable is connected in a dry

environment and that the connection point is lower than the
motor if possible.

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.
