NOTE
For CE versions the cable will need to be routed through the EMC filter box first. See following illustration.

3. Connect the individual cables as shown. Connect the power cable ground cord to the ground terminal block.
CAUTION
The clear connections cover must remain in place.
4. If required pass a system ground cable (F1) through the last opening in the connections cover support panel
next to the input power cable. Connect the cable to the ground terminal block on the power supply rear panel.
Refer to the Ground Connections Section for full details and procedures on proper system grounding.
