Heating voltage supply
CAUTION!
Before connecting, ensure that the mains voltage corresponds with the
heating voltage for the unit (see type plate).
The connection to the heating voltage is made in accordance with the wir­
ing diagram, to the terminal block “XE1” in the control compartment. The
customer is to install a service switch “Q5” (disconnecting device with a
minimum contact opening of 3 mm is an essential requirement) and a fuse
group “F5” (essential requirement, fuses are to be as detailed in the fol­
lowing table) in the supply line. The supply wiring is to be fed into the unit
via the clamp strap on the bottom of the unit.
Note : Double units have separate heating voltage supplies for each cylinder.
