This description supplements the operating instructions
of the fan manufacturer with details on the electrical
connection of the winter controller. Mechanical and
electrical hazards may arise from the fans. Therefore,
please read the fan operating instructions carefully and
keep them available at the refrigeration system
throughout the lifetime of the condensing unit!
When working on the electrical system:
DANGER
Electric shock!
Electric charge > 50 μC! Life-threatening
voltages on fan connection cables even after
disconnecting the voltage supply!
After disconnecting the voltage, wait five
minutes before touching the cables. First short-
circuit the connection cables for N (blue), L
(black) and PE (green-yellow)!
