shock hazards.
1.2 INSULATION RESISTANCE TEST
1. Unplug the power cord and connect a jumper between 2 pins (black and white).
2. The grounding conductor (yellow/green) is to be open.
3. Measure the resistance value with an ohm metre between the jumped lead and each exposed metallic part
on the equipment at all the positions.
4. The value should be over 1M
