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 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).
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
.
For safety reasons the additional installation of a residual current circuit breaker in the mains supply
line (supplied by others) is recommended. However, the local electrical installation regulations must
be observed and adhered to.
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.
