Step 2 - Fit cage nuts
Fit cage nuts in the correct positions to match the screw holes in the APS rack
mounting brackets.
Step 3 - Mount the APS
1
Remove the ground connection bolts on the sides of the APS to allow clearance
to mount in rack.
2
Lift the APS to the correct position in the rack.
A suitable mechanical support or a second person must support the weight of the
APS.
3
Attach the APS using four rack mounting screws. Tighten the screws.
Step 4 - Grounding
The grounding arrangement of your communications equipment determines how
the dc common bus of the dc power system is referenced to ground.
There are two options, Either:
•
the dc supply is referenced (bonded) to a telecom ground electrode (Step
4A), or
•
the dc supply is referenced (bonded) to the ac ground, via the chassis (Step
4B).
The APS is supplied with the dc common bar bonded to the chassis via a link on the dc
common bar.
