Connecting the operating voltage
Caution
Damage to components!
Provide the load voltage and the operating voltage supply as a
circuit with limited energy as per IEC/DIN/EN 61131-2, or
always make sure there is a fuse protection of maximum 10 A
(see graphic “Block circuit diagram for supplying the +24 V
supply”).
The operating voltage for supplying the internal electronics of the installed modules
(peripheral and optional modules) is supplied via the central control unit. The central
control unit converts the supplied operating voltage into the required internal operating
voltages. These are forwarded to the installed modules via the bus plug.
The operating voltage connection is designed with reverse polarity protection within the
permissible operating voltage range.

3.4.2
Earthing the multi-axis control system CMXR
The correct earthing for the device is important for faultless operation and electrical
safety. For earthing, you must produce a low-impedance connection between the device's
earth terminal and the earth potential. A low-impedance connection can be achieved by
using the shortest possible length of a low-impedance cable and a large contact surface
area. The earth terminal is located underneath the housing.
