HIGH VOLTAGE POWER SUPPLY INSTALLATION & MAINTENANCE

The Power Supply Should Not Be Used In An Explosive Or Flammable Area.

The Model 7960 Power Supply requires a 115V, 50/60Hz or 230V, 50/60Hz power source. The voltage selector switch

must be in correct position before turning the power on to the unit. If the correct voltage is not selected, the fuse will

break when the power is turned on.

The Model 7960 comes with (2) removable power cords that use an IEC C13 connection to plug into the back of the

power supply. One of the cords uses a NEMA 5 plug that must plugged into a grounded outlet. If it is not grounded

properly, it will produce a shock and will not work properly. The other cord has a green or green with yellow trace

ground wire, a bare shielding ground wire, a blue return wire and a brown live/hot wire. The shielding ground wire and

green with yellow trace or green wire must be bonded together before installing into a plug to insure proper shielding is

in place. Failure to do this may cause interference with other electrical appliances. Additional grounding can be

obtained by attaching a ground wire between a grounded metal surface and the grounding terminal of the power supply.

Mounting flanges are provided at the base of each power supply. The power supply can be bolted to the machine frame

for uniform grounding. If grounding cannot be obtained through the machine, it is best to connect to earth ground

through a grounding rod or copper cold water system.
