•
On appliances without control unit, the main switch must be integrated into the wiring. Rated current 25 A.
Cable harness wired to terminal strips; otherwise no other wiring.
•
Make all connections in accordance with the regulations of the local power supply utility.

(May become loose during transport.)
•
The motor overload relays installed for the EC fans and electric heating coils are used as circuit breakers and
do not need to be set to the rated current.
•
Compare mains voltage with control panel supply voltage.
•
Max. line length for sensors, servomotors, 24V control cables 50 m. Never route together with 230/400 V cables,
or alternatively use shielded cables.
