SELECT SuITAbLE LOCATION
LOCATION AND VENTILATION FOR COOLING Place the welder where clean cooling air can freely circulate in through the rear louvers and out through the case sides. Dirt, dust, or any foreign material that can be drawn into the welder should be kept at a mini- mum. Failure to observe these precautions can result in excessive operating temperatures and nuisance shutdowns.
LIFTING
Both handles should be used when lifting the FX450. When using a crane or overhead device a lifting strap should be connected to both handles. Do not attempt to lift the FX450 with accessories attached to it.
STACKING
The FX450 cannot be stacked.
ENVIRONMENTAL LIMITATIONS
The FX450 is IP23 rated for use in an outdoor envi- ronment. The FX450 should not be subjected to falling water during use nor should any parts of it be sub- merged in water. Doing so may cause improper oper- ation as well as pose a safety hazard. The best prac- tice is to keep the machine in a dry, sheltered area.
CAuTION
Do not mount the FX450 over combustible sur- faces. Where there is a combustible surface directly under stationary or fixed electrical equip- ment, that surface shall be covered with a steel plate at least .060” (1.6mm) thick, which shall extend not less than 5.90” (150mm) beyond the equipment on all sides.
INPuT AND GROuNDING CONNECTIONS
MAChINE GROuNDING
The frame of the welder must be grounded. A ground terminal marked with the symbol shown is located inside the reconnect/input connection area for this purpose. See your
local and national electrical codes for proper ground- ing methods.
hIGh FREQuENCY PROTECTION
Locate the FX450 away from radio controlled machin- ery. The normal operation of the FX450 may adverse- ly affect the operation of RF controlled equipment, which may result in bodily injury or damage to the equipment.
