Step 4A - Bond dc output to a telecom ground electrode (if required)
Ignore this Step if the dc supply must be referenced (bonded) to the ac ground, via
the chassis (see Step 4B).
If the grounding policy at the site requires that the dc supply must be referenced to a
telecom ground electrode, then:
1
Remove the link that bonds the dc common bar to the chassis.
2
Connect a telecom ground link cable to the dc common bar as shown in the
following diagram. Use:
Wire:
Multi-strand, copper conductor, 3/0 AWG* with
green/yellow insulation
Strip length:
5/8" (16mm)
Crimp lug:
FCI-Burndy type YAV27L-TC14-FX
Crimp tool:
FCI-Burndy type MY29-11
* If 3/0 AWG cable is not available, use 2/0 AWG cable and appropriate UL-Listed
Crimp Lug.
3
Tighten terminal to 3.9 - 4.5Nm (35 - 39 inch-pounds).
4
Terminate the cable at the site's telecom ground electrode directly or via the site's
telecom ground bus bar, if provided.
Remove link between dc common bar and
chassis.
Telecom ground link cable to site's telecom
ground electrode (3/0 AWG*)
