1. Unplug the power cord and check for continuity between the earth ground connection on the plug and the Interface Board
Cover. There should be zero ohm resistance.
2. With the unit unplugged, short the AC live-neutral of the plug with a jumper wire.
3. Turn ON the power switch.
4. Measure the resistance value with an ohmmeter between the jumpered AC plug and an exposed metal cabinet part, such as
screwheads, etc. (Refer to Fig.2)
Note
Some exposed parts may be isolated from the chassis by design. They read infinity.
5. If the measurement is less than 1M
, a possibility for electric shock may exit.
Note
This hazardous condition must be corrected before the unit is returned to the end user.
