Note: The customer-supplied control cable must be shielded (on both ends). Do not expose the cable shield on the control side more than 12 inches from TB2 on the interface power module. Splice the cable shield and ground it to station ground and the grounding lug on the interface power module (below TB2). The junction box must be grounded directly to station ground.

IMPORTANT
All external wiring inputs to the Form 6 recloser control must be routed within 8 inches of their corresponding ground. During a surge, a potential of approximately 1.5 kV per foot can develop in the conductors. Differences between conductor and ground path lengths can add additional stress to the control components in the event of a power surge.
