Installation 5
2.3.1 Cable Grounding
Except for the power cord, all cables routed through
the cord grips should be grounded against the
indicator backplate. 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 backplate studs adjacent to cord
grips. Install grounding clamps only for cord
grips that will be used; do not tighten nuts.
• Route cables through cord grips and grounding
clamps to determine cable lengths required to
reach cable 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 (15 mm)
past the grounding clamp (see Figure 2-2).
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 (15 mm) of insulation only to expose the
braid where the cable passes through the
clamp (see Figure 2-2).
• 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 through cord grips and
clamps. Ensure shields contact grounding
clamps as shown in Figure 2-2. Tighten
grounding clamp nuts.
• Finish installation using cable mounts and ties to
secure cables inside of indicator enclosure.
