ductor against the
terminal.
•
Force down the spring
and push the con-
ductor into the termi-
nal.
•
Relieve the spring -
the conductor is secu-
rely clamped
Cable cross-section required:
The currents specified under the machine
data for the series WSG-W8 refer to duty
type S3-40%. This must be taken into
account when selecting the cable cross-sec-
tion required. The continuous Ir.m.s. value
required for the selected cable is approxi-
mated from:

Winding protection
A triple PTC thermistor is used for monitoring the tem-
perature of the motor winding. The triple type permits all
of the three motor phases to be monitored.
The PTC thermistor installed in the winding
must be evaluated in the control system or
frequency converter to protect the motor
from overtemperature.
The operating voltage of the PTC thermis-
tors is not allowed to exceed 25 V DC.
