The voltage supply (L1, N and PE) is to be connected
in accordance with the wiring diagram to the correspon-
ding terminals of terminal strip "X9". The connecting
cable must be led through a cable gland into the control
compartment.
The installation of the fuses "F5" (fuse values, see the
table below) and the electrical isolator "Q5" (all pole
disconnecting device with a minimum contact clearance
of 3 mm, supplied by others) in the mains supply line
are mandatory.
For safety reasons the additional installation of a re-
sidual 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 prox-
imity 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 type
plate 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.
