10.2 Safety Tests after Repair
ATTENTION!
Following every repair or dismantling the enclosure, the service engineer
should perform two safety electrical test as follows:
1. Enclosure Leakage Current Test.
. Perform the test using the Megger: (electrical potential 500 V). The
insulation resistance should be at least 2 M
Ω
.
Success criteria - no leakage.
2. Protective Earth Impedance Test
Measure the resistance between Grounding of any metallic port end
the Grounding pin of the power cord plug, use the Ohmeter.
Success criteria resistance - 0.3
Ω
.
Upon completion of the tests, document and sign work order and log
book.
