areas:
1.
Insulated resistance The insulated resistance must be more than 2MΩ.
2.
Grounding work After fi nishing grounding work, measure the grounding
resistance by visual detection and using the grounding resistance tester. Make
sure the grounding resistance is less than 4Ω.
3.
Electrical leakage check (performing during test while unit is on) During a test
operation after completed installation, use the electroprobe and multimeter
to perform an electrical leakage check. Turn off the unit immediately if leakage
happens. Try and evaluate diff erent solutions until the unit operates properly.
