3.5.3 ELECTRICAL INPUT CONNECTIONS
•
DO NOT TOUCH live electrical parts.
•
SHUT DOWN welding power source, disconnect input power employing lockout/tagging
procedures. Lockout/tagging procedures consist of padlocking line disconnect switch in
an open position, removing fuses from fuse box, or shutting off and red-tagging circuit
breaker or other disconnecting device.
WARNING:
ELECTRIC SHOCK can kill; a SIGNIFICANT DC VOLTAGE is present after removal of
input power until the internal components have time to discharge.
A 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.
