4 920i Panel Mount Installation Instructions
Cable Grounding
All cables routed into the panel mount enclosure
should be grounded against the indicator enclosure. Do
the following to ground shielded cables:
• Use the lockwashers, clamps, and kep nuts
provided in the parts kit to install grounding
clamps on the enclosure studs adjacent to cord
grips.
Insulated cable
Foil (silver side out) Grounding clamp
Shield wire (cut)

back on cable insulation

Figure 6. Cable Installation with Grounding Clamp
• Route cables under cabling bar (see Figure 6)
and through grounding clamps to determine
c a b l e l e n g t h s r e q u i r e d t o r e a c h c a b l e
connectors. Mark cables to remove insulation
and shield as described below:
• For cables with foil shielding, strip insulation
and foil from the cable half an inch (13 mm)
past the grounding clamp (see Figure 5). Fold
the foil shield back on the cable where the
cable passes through the clamp. Ensure silver
(conductive) side of foil is turned outward for
contact with the grounding clamp.
• For cables with braided shielding, strip cable
insulation and braided shield from a point just
past the grounding clamp. Strip another half
inch (13 mm) of insulation only to expose the
braid where the cable passes through the
clamp.
• For load cell cables, cut the shield wire just
past the grounding clamp. Shield wire function
is provided by contact between the cable shield
and the grounding clamp.
• Route stripped cables under cabling bar and
through the clamps. Ensure shields contact
grounding clamps. Tighten grounding clamp
nuts.
• Use cable ties to secure cables to cabling bar.
