→ Use only cables that meet the specified installation

requirements for voltage, current, insulation material, load etc.

→ Route cables such that they cannot be touched by any

rotating parts.

CAUTION
Electrical voltage

The fan is a built-in component and features no electrically
isolating switch.

→ Only connect the fan to circuits that can be switched off with

Translation of the original operating instructions

an all-pole separating switch.

→ When working on the fan, you must switch off the

installation/machine in which the fan is installed and secure it
from being switched on again.

NOTE
Water penetration into leads or wires

Water enters at the cable end on the customers side and can
damage the device.

→ Make sure that the cable end is connected in a dry

environment.

Connect the device only to circuits that can be switched off
using an all-pole disconnecting switch.

4.2.1 Prerequisites

; Check that the data on the type plate match the connection data.

; Before connecting the device, ensure that the supply voltage matches

the operating voltage of the device.

; Only use cables designed for current according to the type plate.

For determining the cross-section, follow the basic principles in
accordance with EN 61800-5-1. The protective earth must have a
cross-section equal to or greater than the outer conductor cross­section.
We recommend the use of 105°C cables. Ensure that the minimum
cable cross-section is at least
AWG26/0.13 mm².

Protective earth contact resistance as per EN 60335

Compliance with the resistance specifications as per EN 60335 for the
protective earth connection circuit must be verified in the 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

Excessive current may occur with speed control using
transformers or electronic voltage regulators (e.g. phase angle
control). In addition, depending on how the unit is installed,
noise and vibration can occur with phase angle control.
Vibrations can lead to bearing damage, which can lead to
premature failure.

4.2.3 Frequency inverter

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

For operation with frequency converters, fit sinusoidal filters that
work on all poles (phase-phase and phase-earth) between the
frequency converter and the motor.
During operation with frequency converters, an all-pole sine
filter protects the motor against high-voltage transients that can
destroy the winding insulation system, and against harmful
bearing currents.

Heating-up of the motor when using a frequency converter must be
checked by the customer following installation in the end device.
