At the end of the cable is a premounted -pole plug. An
appropriate socket has been provided on the power sup-
ply unit NE- or screw terminal PCB VHM/KV and KVS.
Please note that the heater does not contain a ther-
mostat switch and therefore heats up immediately
as soon as power is connected.
For this reason, we recommend connecting electri-
cal supply to the heating only just before closing the
housing.
