2. After servicing, see to it that all the protective devices such as
insulation barriers, insulation papers shields are properly installed.
3. After servicing, make the following leakage current checks to
prevent the customer from being exposed to shock hazards.
(This “Safety Precaution” is applied only in U.S.A.)
1. Before servicing, unplug the power cord to prevent an electric
shock.
2. When replacing parts, use only manufacturer’s recommended
components for safety.
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.
1.1.1. LEAKAGE CURRENT COLD CHECK
1. Unplug the AC cord and connect a jumper between the two prongs
on the plug.
2. Measure the resistance value, with an ohmmeter, between the
jumpered AC plug and each exposed metallic cabinet part on the
equipment such as screwheads, connectors, control shafts, etc.
When the exposed metallic part has a return path to the chassis,
the reading should be between 1M and 5.2 . / When the
exposed metal does not have a return path to the chassis, the
reading must be
.
