For safety reasons, it is very important that the
motor be properly and carefully earthed.
Lift machine of WSG-10 are equipped with ECN1313
EnDat or ERN1387 encoder from Heidenhain GmbH.
or encoder of TS5213N2503 from TAMAGAWA.
1. ECN1313 EnDat is connected via a 12-pole signal
coupling fitted ot the motor.
2. ERN1387 is connected via a 14-pole signal coupling
fitted to the motor.
3. TS5213N2503 is connected via a 12-pole signal
from the endof the motor.
We can also provide other measuring systems on
request.

Warning
Warning
It is essential to use the earthing terminal
in the terminal box. In addition, an earthing
screw is provided on the motor frame for
the connection of a protective or earthing
conductor as specified in VDE 0100 and VDE
0141 respectively.
The motor terminals of the synchronous
lift machines, type WSG-10, can be short
circuited, if required, to brake the lift
machine faster. This is, however, only
permissible at speeds less than the rated
speed of the respective motor.
We recommend the use of an appropriate
cable set to connect the measuring system
to the converter system. Cable sets can be
supplied as accessories.
The measuring system of the WSG-10 lift
machines is matched to the associated
converter. Do not change the adjustment
as this may make it impossible to use the
motor.

Caution
The PTC thermistor of stator iron must be
evaluated by the elevator control system in
order to avoid that the motor overheated.
