2.3 Electrical connection
Power cable: The system connection shall be performed with a cable of sufficient cross-section (max.
4 mm
2 )
Control unit: 4-pole plug with screw terminals 1.5 mm 2
(electrically separated from the system potential)
PTC resistor/brake: 3 x 2-pole screw terminals with 1.5 mm 2 (on system potential)
Cable entry: The following are available: 1 x M25 and 1 x M12 and 1 x M16. If applicable, 1 x M12 may
already be reserved by the brake connection. Other screw connections are available, but
cannot be freely allocated.
