3. Check the condition of the power cord. Replace if wear or
damage is evident.
4. After servicing, be sure to restore the lead dress, insulation
barriers, insulation papers, shields, etc.
5. Before returning the serviced equipment to the customer, be sure
to make the following insulation resistance test to prevent the
customer from being exposed to a shock hazard.
2.2. Insulation Resistance Test
1. Unplug the power cord and short the prongs of the plug with a
jumper wire.
2. Turn on the power switch.
3. Measure the resistance value with an ohmmeter between the
jumpered AC plug and each exposed metal cabinet part, such as
screw heads, connectors, control shafts, handle brackets, etc.
Measurements should range from 4 MOhm to infinity for
allexposed parts. (refer to
