1. Safety Instructions
Important Safety Notice
Many electrical and mechanical parts in this chassis have special safety-related characteristics.
These parts are identified by in the Schematic Diagram and Replacement Parts List.
It is essential that these special safety parts should be replaced with the same components as
recommended in this manual to prevent Shock, Fire, or other Hazards.
Do not modify the original design without permission of manufacturer.
Leakage Current Hot Check (See below Figure)
Plug the AC cord directly into the AC outlet. Do not use a line Isolation Transformer during this check.
Connect 1.5K/10watt resistor in parallel with a 0.15uF capacitor between a known good earth ground (Water
Pipe, Conduit, etc) and the exposed metallic parts. Measure the AC voltage across the resistor using AC
voltmeter with 1000 ohms/volt or more sensitivity. Reverse plug of the AC cord into the AC outlet and repeat
AC voltage measurements for each exposed metallic part. Any voltage measured must not exceed 0.75 volt
RMS, which is, corresponds to 0.5mA. In case any measurement is out of the limits specified, there is
possibility of shock hazard and the set must be checked and repaired before it is returned to the customer.
