Operating instructions
W6E500-KJ05-11
Translation of the original operating instructions
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 Motor protection
CAUTION
Voltage
The device is a built-in component and has no disconnecting
switch.
→ Connect the device to a suitable tripping unit.
→ Only connect the device to circuits that can be switched
off with an all-pole disconnection switch.
→ When working on the device, secure the system/
machine in which the device is installed so as to prevent it
from being switched back on.
NOTE
Lack of motor protection
Without motor protection, the motor can overheat and suffer
damage.
→ Connect the thermal overload protector installed in the
winding.
The motor is provided with a thermal overload protector (TOP). Always
check that the thermal overload protector (TOP) is properly connected
before start-up. Failure to connect the thermal overload protector correctly
will invalidate your warranty claim.
Externally wired thermal overload protectors must be integrated in the
control circuit of a tripping unit. The fan’s power supply is passed through
the main circuit of the tripping unit. In the event of a fault, an automatic
restart after cooling must be prevented.
The following contact ratings must not be exceeded:

AC
250 V
