Electrical Connection
Before working on the unit, switch off the power supply and secure it against being switched on again! Check that there
is no power flowing! Electrical connections may only be made by a specialist and in compliance with the applicable
regulations. The unit may not be put into operation if there is visible damage to the housing, e.g. cracks.
The unit may not be accessible from behind.
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.
The customer must provide an all-pole disconnecting device, e.g. an emergency heating switch.
The cables being connected to the unit must not be stripped by more than 55 mm, and the cable jacket must reach into
the housing just to the other side of the strain relief.
