Electrical Connection; Installation - Wolf COB Installation Instructions And Technical Manual

General notes
The installation must be carried out by a
licensed electrical contractor. Observe VDE
regulations as well as all local regulations by
your power supply utility.
The power supply terminals are 'live' even when
the ON/OFF switch has been switched OFF.
Isolate the boiler from the power supply
before changing the fuse. The ON/OFF switch
on the boiler does not provide separation
from the power supply. Danger through 'live'
electrical components. Never touch electrical
components or contacts as long as the boiler
has not been isolated from the power supply.
Danger to life.

Terminal box
Terminal box
The terminal box is supplied fitted to the back panel of the
boiler.
If necessary, the terminal box can be mounted on the wall to
the right, to the left or above the boiler.
The control, regulating and safety equipment are fully wired
and tested.
Power supply
In the case of a permanent connection, provide the power
supply via a mains isolator (e.g. fuse, heating system
emergency stop), which ensures at least 3 mm contact
separation for all poles. Connecting cable, flexible, 3 x 1.0 mm²
or rigid, max. 3 x 1.5 mm².
The maximum current carrying capacity of the outputs is 2 A,
but a total of 5 A must not be exceeded.
Installation information, electrical connection
Isolate the system from the power supply before opening the
casing.
Unclip the terminal box from the holder.
Open the terminal box.
Insert the strain relief into the holes provided.
Strip approx. 70 mm off the power cable insulation.
Push the cable through the strain relief and secure the strain
relief.
Terminate the appropriate cores at the Rast-5 plug.
Push the inserts back into the terminal box casing.
Insert the Rast-5 plug.
Fit the cover.
