Electrical Connection - Wolf COB Technical Manual And Installation Instructions

General information
The installation may be carried out only by an
approved electrical contractor. Observe VDE
regulations as well as all local regulations of your
power supply utility.
The device power supply terminals are 'live' even
when the ON/OFF switch has been switched OFF.
For installation in Austria: Observe the ÖVE
regulations and requirements and those of your
local power supply utility.
Isolate the boiler from the power supply before
changing the fuse. The ON/OFF switch on the
appliance does not provide isolation from the
power supply. Danger from '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
In the delivered condition, the terminal box is fitted to the back
panel of the boiler.
Unclip the terminal box from the holder. The terminal box can
be mounted on the wall to the right or left of the boiler. The
control and safety devices 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.
Power cable, flexible, 3x 1.0 mm² or rigid, max. 3x 1.5 mm².
The maximum current carrying capacity of the outputs is 2 A,
but a total of 5 A must not be exceeded.
