After correcting the original service problem, perform the following safety check before releasing the unit to the customer.

Leakage current Check

Measure the leakage current to a known earth ground (water pipe or conduct etc.) by connecting a leakage current

T NR3008

tester between the earth ground and exposed metal parts of the unit (input/output ground terminals, screw heads or metal overlays etc.)

Plug the power supply cord directly into a 120Vac 601-12 wall socket and tum ON/STANDBY button on.

Any current measured must not exceed 0.5mA.

3. Memory Backup
