The following inspections and maintenance tasks are recommended at least two times per year
for good performance.

Check all the naked wires to ensure insulation is not damaged by sun exposure, frictional wear,
dryness, insects or rats, etc.

Verify the indicator display is consistent with the actual operation.

Confirm that terminals have no corrosion, insulation damage, high temperature, burnt/discolored
sign, and tighten terminal screws to the suggested torque.
