Terminalbox
In the delivered condition, the terminal box is tted 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, exible, 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.
