electricity leakage and fire.
After repair, check for insulation between the charged part and non-charged metal part
(ground terminal) using an insulation resistance tester (500V) and ensure at least 2MΩ
resistance.
If the insulation resistance value is low, it indicates the risk of disasters, such as electricity leakage

and electric shock, on the client's premises.
In case of performing circuit inspection while the circuit is connected to a power source (if
such condition is necessary), use rubber gloves and other measures to prevent contact
with the charged part.
Otherwise, one will risk electric shock from contacting the charged part.
