Terminal box
The terminal box is supplied tted 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, exible, 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.
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.
