INSTALLATION 10 Manual 0-2337
ELECTRIC SHOCK can kill; SIGNIFICANT DC VOLTAGE is
present after removal of input power.
• DO NOT TOUCH live electrical parts.
• SHUT DOWN welding power source, disconnect input power
employing lockout/tagging procedures, wait 60-80 seconds,
and measure voltage on input capacitors according to instruc-
tion manual before touching any parts. Lockout/tagging
procedures consist of padlocking line disconnect switch in open
position, removing fuses from fuse box, or shutting off and red-
tagging circuit breaker or other disconnecting device.
Operate the welding power source from a three-phase, or single-
phase if derated, 50/60 Hz, AC power supply. The input voltage
must match one of the electrical input voltages shown on the
input data label on the unit nameplate. Contact the local electric
utility for information about the type of electrical service avail-
able, how proper connections should be made, and inspection
required.
The line disconnect switch provides a safe and convenient means
to completely remove all electrical power from the welding
power supply whenever necessary to inspect or service the unit.
This unit is equipped with a three-conductor with ground power
cable that is connected at the welding power source end for three-
phase electrical input power.
