Electrical connection
Isolate the gas condensing boiler from
the power supply before changing a
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
gas condensing boiler has not been
isolated from the power supply. Risk
to life.

- Push the cable through the strain relief and secure
the strain relief.
- Pull off the Rast5 plug.
- Terminate the appropriate cores at the Rast5 plug.
Leave the cores for the earth conductor gr/ye approx.

The control, regulating and safety equipment are fully
wired and tested.
You only need to connect the power supply and the
external accessories.
Power supply
Create a permanent connection for the power supply.
Provide the power supply via a main isolator (heating
system emergency stop switch) that ensures at least
3 mm contact separation for all poles.
Power cable, flexible, 3 x 1.0 mm² or rigid, up to
3 x 1.5 mm².
