Manual 0-4976 2-3 INSTALLATION
Power Supply Dimensions & Weight Ventilation Clearance Requirements
NOTE
Weight includes torch & leads, input power cord, and work cable with clamp.
CAUTION
Provide clearance for proper air flow through the power supply. Operation without proper air flow will inhibit
proper cooling and reduce duty cycle.

NOTES
Refer to Local and National Codes or local authority having jurisdiction for proper wiring requirements.
Refer to Local and National Codes or local authority having jurisdiction for proper wiring requirements.
Cable size is de-rated based on the Duty Cycle of the equipment.
The suggested sizes are based on flexible power cable with power plug installations.
Cable conductor temperature used is 167° F (75° C).
An energy limiting fuse UL Class RK-1 (examples: BUSS LPS/LPN-RK or Gould-Shawmut AZK-A6K) should
be used to minimize damage to Plasma Cutting, Welding or power distribution equipment.
NEVER use replaceable element fuses like UL Class H, or "one-time" fuses like UL Class K5.
Extension Cords
Extension cords must meet National Electric Code Guidelines (and OSHA Guidelines, where applicable). Exten-
sion cords must have the same rating as the service and must have a three-pronged plug.
