The
voltage supply
(L1, L2, L3 and PE) is to be connected in accordance with the wiring diagram to
the corresponding terminals of the option TR. The supply wiring is to be fed into the unit via the clamp
strap on the bottom of the unit.
Note: On double units consisting of two housings the heating voltage supply for module B is connected
to the corresponding terminals of the terminal strip "THV". The control voltage supply to module B is
established via the supply cable connected to the terminal strips "X7" on the driver boards of module A
and module B.
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.
