3.3 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 M16 and 1 x M12. The 1 x M12 screw plug
may already be reserved by the brake connection and the M16 by the optional M12 plug.
