C.1 ELECTRICAL CONNECTION
DANGER
Before working on the unit, switch off the power supply and secure it against being switched on again! Check for the absence of
power!
Electrical connections may only be made by a specialist and in compliance with the applicable regulations. Do not use the control-
ler if the housing shows visible damage.
CAUTION
The cables being connected to the unit must not be stripped by more than 55mm, and the cable jacket must each into the housing
just to the other side of the strain relief.
CAUTION
Controller and VFS sensor have to have the same ground potential. The VFS sensor has a functional earth connector (PELV). The
PE-connector of the controller has to be connected to the pipe system near the sensor.
CAUTION
Low-voltage cables such as temperature sensor cables must be routed separately from mains voltage cables. Feed temperature
sensor cables only into the left-hand side of the unit, and mains voltage cables only into the right-hand side.
CAUTION
The customer must provide an all-pole disconnecting device, e.g. a heating emergency switch.
