6.4 Power supply connection
Description For connection to the mains, the robot controller is equipped with a 3-pole
socket for non-heating appliances. The robot controller must be connected to
the mains via the device connection cable included in the scope of supply.
The robot controller can be connected to the mains via the following device
connection cables:
 with mains connector
 without mains connector
Infeed
 200 V - 230 V AC, single-phase, two-phase (with grounded neutral (as
symmetrical as possible) between the phases used)
 50 Hz ± 1 Hz or 60 Hz ± 1 Hz
Fusing
 2x 16 A slow-blowing, type C (1 (2)x phase; 1x neutral conductor (option-
al))
6.5 Safety interface X11
Description EMERGENCY STOP devices must be connected via safety interface X11 or
linked together by means of higher-level controllers (e.g. PLC).
Wiring Take the following points into consideration when wiring safety interface X11:
 System concept
 Safety concept
6.5.1 X11 safety interface
The X11 safety interface is wired internally to the CCU.
