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.

G115.1

The control cabinet must be grounded. A grounding connector 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 conductors for the Form 5 must be routed parallel to a corresponding 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.
