for proper operation of relays and

 

 

 

 

contactors.

 

 

 

 

Make sure input and output connections

 

 

 

 

are tight and that no damaged wires or

 

 

 

 

damaged insulation exists.

 

 

Inspect housing for rust spots.

Clean and touch-up rust spots with paint.

 

 

Inspect lightning arrestor connections.

Tighten any loose connections. Replace

 

 

 

 

charred or burnt wiring or broken

 

 

 

 

arrestors.

 

 

Perform a short-circuit test.

Refer to Short-Circuit Test in this section.

 

 

Perform an open-circuit test.

Refer to Open-Circuit Test in this section.

 

Unscheduled

Check load on regulator.

At installation and subsequent load

 

 

 

 

changes make sure that the output rms
