tight to reduce high frequency leakage. |

5.The work terminal must be connected to a ground within ten feet of the welder, using one of the
following methods:
a)A metal underground water pipe in direct contact with the earth for ten feet or more.
b)A 3/4” (19mm) galvanized pipe or a 5/8” (16mm) solid galvanized iron, steel or copper rod driven at least eight feet into the ground.
The ground should be securely made and the grounding cable should be as short as possible using cable of the same size as the work cable, or larger. Grounding to the building frame electrical conduit or a long pipe system can result in re- radiation, effectively making these members radiating antennas.
6.Keep all access panels and covers securely in place.
7.All electrical conductors within 50 ft (15.2m) of the welder should be enclosed in grounded rigid metallic conduit or equivalent shielding. Flexible metallic conduit is generally not suitable.

8.When the welder is enclosed in a metal building, several good earth driven electrical grounds (as in 5 (b) above) around the periphery of the building are recommended.
Failure to observe these recommended installation procedures can cause radio or TV interference problems and result in unsatisfactory welding performance resulting from lost high frequency power.
INPUT CONNECTIONS
Be sure the voltage, phase, and frequency of the input power is as specified on the rating plate, located on the rear of the machine. Refer to Figure A.1.
Welder supply line entry provision is in the case rear panel with a removable cover over the input connection panel area. Entry is through a 1.7 in (43mm) diameter hole in the case back. See Figure A.1.
GROUND CONNECTION
The frame of the welder must be grounded. A ground
terminal marked with the symbol 
is located at the bottom of the input box for this purpose. See your local and national electrical codes for proper grounding methods.
INPUT SUPPLY CONNECTIONS
Have a qualified electrician connect single phase input power leads to L1 and L2 of the input panel in accor- dance with all local codes and national electrical codes. Refer to the connection diagram located on the inside of the cover of the Reconnect Panel.
