Connection of the motor supply cable from an SHE or ventilation control unit or a power supply unit to the inputs of the
WPS2/A and WPS2/B control unit.
Terminal 3:
Monitoring line for SHE control centres
Terminal 2:
Motor input voltage
Terminal 1:
Motor input voltage
Please note the following polarity when connecting the motor input voltage:
Motor voltage in opening direction: - at terminal 1, + at terminal 2
Motor voltage in closing direction: + at terminal 1, - at terminal 2

, the energy supply is provided by the motor circuit (terminals 1, 2), for
variant
WPS2/B
.
N - > In position

Variant WPS2/B
The jumper for the power supply via the motor circuit (“Power supply by motor circuit”) is to be set to position
M
if no
separate power supply unit is available and the power supply is not provided separately from the SHE/ventilation
control unit.
At the same time, the parameter "Feed-in from Motor group" must be set
Variant WPS2/A
In position
N
, the energy is supplied by a separate power supply (e.g. VNT 2.5 A) on terminals 8. 9.
If the energy supply of WPS2/A is realized with a ventilation or SHE control unit, the following parameters must
be maintained:
motor outputs provide “continuous voltage”;
no stroke limiting;
no time delays.
