Protective earth contact resistance according to EN 61800-
5-1
Compliance with the resistance specifications according to
EN61800-5-1 for the protective earth connection circuit must be
veridied 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
Residual current circuit breaker (RCCB)
If the use of a residual current device (RCD) is
required in your installation, only pulse-current and/or
AC/DC-sensitive residual current devices (type A or
B) are permissible. As with variable frequency drives,
residual current devices cannot provide personal
safety while operating the device.
4.2.3
Voltage control
With speed control using transformers or electronic
voltage regulators (e.g. phase control), excessive
current may occur. In addition, depending on how the
device is installed, noises can occur with phase
control.
4.2.4
Frequency inverter
Please sure a variable frequency drive only after consultation
with ebm-papst.
When a variable frequency device is used for speed adjustment,
the maximum safe operating speed (see 3.2 Nominal data) may
not be exceeded.
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 operating 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 of the motor due to the use of a variable frequency drive
must be checked in the application by the customer.

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 relif are dependent on the
cable used.
→ This must be checked by the user.
Fig. 1: Preparing cables for terminal box.
4.3.2
Connecting wires to terminals
Remove the cap from the cable gland.
Only remove caps where cables are inserted.
Route the wire(s) (not included in scope of delivery) into the
terminal box.
First connect the “PE” (protective earth).
Connect the wires to the corresponding terminals.
Connect the wires to the corresponding terminals
Connect the thermal overload protector (TOP)
Use a screwdriver to do so.
When connecting, ensure that no wire ends fan out.
The terminal strip is equipped with a penetration guard
Seal the terminal box.
4.3.3
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 gland, 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 lying flat
Make sure the cable is routed in a U-shaped loop (water trap).
