Grounding The Control - Cooper S280-79-10 Install And Operation Instructions

Kyle Form 5, Form 5 UDP, Form 5 DC NOVA Recloser Control Installation and Operation Instructions

Grounding the Control

WARNING: Hazardous Voltage. The recloser
and control must be solidly grounded. Follow all
locally approved procedures and safety practices when
grounding this equipment. Improper grounding can
result in contact with high voltage, which will cause
death, severe personal injury.
The control cabinet must be grounded. A grounding con-
nector on the underside of the cabinet will accommodate
No. 14 solid through No. 4 stranded conductors.
Suggested methods for grounding the control and
recloser are shown in Figures 29, 30, and 31.

Figure 29 illustrates grounding methods for 3-wire
ungrounded and 4-wire multi-grounded systems with local
supply voltage transformer.
Figure 30 illustrates grounding methods for 3-wire
ungrounded and 4-wire multi-grounded systems with
remote supply voltage transformer.
Figure 31 illustrates grounding on a 3-wire uni-grounded
system.

For effective surge protection all control and power con-
ductors for the Form 5 must be routed parallel to a corre-
sponding ground path. For example, the AC power supply
for the control should be parallel to and equal in length to
the transformer ground path. The control cable should be
parallel to and routed close to the recloser ground path.
