Measure insulation resistance to earth with Megger

Is the insulation resistance more than 1MΩ?

Danger! Live Electrical Connections!

Confirm that only qualified technicians are performing the tasks

Ensure all power supply, including remote controls, are disconnected before maintenance

Wait at least 5 minutes after power isolation before testing for high voltage

Observe proper Lock-Out / Tag-Out procedures

Visual Inspection and Terminal Tightening

Tighten terminals on isolators and printed circuit boards as necessary

Visual check for damage, rust and dust accumulation

For highly corrosive environment, wash panels quarterly with water & neutral detergent solution

Repair / re-paint where required

Check for obstructions & free flow of water

Clean to eliminate obstructions/sludge & check condition of pan

Visual check for damage, rust and dust accumulation

Is the environment highly corrosive?
