3.3  Cooling the devices 
Cooling air must be able to ow through the device without restriction. On installation in 
switch cabinets with convection (= heat loss is dissipated to the outside via the cabinet

must be improved.

Step Action Comment
1.
Arrange the supply unit on the backing plate as per  
Figure 3.1. 
Please also provide enough space to the left of the supply 
unit for the MotionOne CM controller.
Align all devices in a line along the top edge of the devices.
This action is necessary to be able to 
couple the DC link using the pre-assem-
bled busbars.
2.
Mark out the position of the tapped holes on the backing 
plate.
Drill holes in the backing plate and cut a thread for each 
xing screw in the backing plate.
Pay attention to the bending radius of the 
connection cables!
For hole spacing and dimensional draw-
ings, see Table 3.1 and Figure 3.4.
3.
Mount the ServoOne CM-P supply unit vertically and butt 
mounted in a row with the axis controllers on the backing 
plate.
The contact surface must be bare metal
