The
heating voltage supply
(L1, L2, L3 and PE or L1, N and PE) is to be connected in accordance with
the wiring diagram to the corresponding terminals of the main contactor "K1" (or to the corresponding
terminals of the optional terminal strip "THV") in the control compartment. The supply wiring is to be
fed into the unit via the cable guide with clamp on the bottom of the unit.
Notes
:
– Double units consisting of two housings have separate heating voltage supplies for each module
(cylinder).
– Large units with two cylinders have a single heating voltage supply which is branched to each of
the two modules.
The installation of the
fuses "F3" and the electrical isolator "Q3"
(all pole disconnecting device with
a minimum contact clearance of 3 mm, supplied by others) in the mains supply line are mandatory.
Note: a table with the values for the fuses "F3" is to be found in
chapter 5.7.7
.
The electrical isolator must be mounted in direct proximity of the control compartment (max. distance
1 m) and must be easily accessible in a height between 0.6 m and 1.9 m (recommended: 1.7 m) .
CAUTION!
Make sure the voltage indicated on the specification label meets the local mains voltage.
Otherwise, do not connect the unit.
The cross-section of the mains cable must comply with the applicable local regulations.
