W ARNINGS AND L ABELS
HIGH VOLTAGE: The voltage of Liberty Weldcell is dangerous
once connected to a power supply. Incorrect installation may
cause damage to the equipment, serious injury, or death.
Consequently, it is essential to comply with instructions in this
manual, local and national safety rules, and follow all safety
procedures including proper lock out and tag out procedures.
Hazardous Voltage: The Variable Frequency Drive (VFD)
uses large capacitors which can hold a charge long after the
power disconnect has been used to disconnect power from the
unit. Do not service the panel until the VFD has fully
discharged.
GROUND CONNECTION: Proper grounding of the equipment
and electrical panel is essential. Do not attempt to operate the
equipment without electrically grounding the panel. The
connection to the earth ground must be proper and provide a
low impedance path to the earth to prevent hazardous
voltages from appearing on equipment
COMPRESSED AIR: Compressed air is used in the operation
of this unit. Follow proper lock out / tag out procedures prior to
servicing the unit. This includes draining the compressed air
reservoir inside the unit. Failing to do so can lead to injury or
hearing loss. Look out – drain tank – do not service while
pressurized.
