Read entire Installation section before starting installation.

SAFETY PRECAUTIONS

WARNING

ELECTRIC SHOCK can kill.

Only qualified personnel should perform this installation.

Only personnel that have read and under- stood the SP-255 Operating Manual should install and operate this equipment.

Machine must be plugged into a receptacle which is grounded per any national, local or other applicable electrical codes.

Turn the power switch on the SP-255 “off” before connecting or disconnecting gun and cable, output cables or other equip- ment.

UNCRATING THE SP-255

Remove the staples from the bottom edge of the car- ton and lift off. Cut the tape securing the two rear wheels to the wooden shipping pallet. Using a 1/2 inch (or 13 mm) wrench or socket, remove the two screws which attach the pallet to the bottom of the SP-255.

LOCATION

Locate the welder in a dry location where there is free circulation of clean air into the louvers in the back and out the front. A location that minimizes the amount of smoke and dirt drawn into the rear louvers reduces the chance of dirt accumulation that can block air pas- sages and cause overheating.

1.Before starting the installation, check with the local power company if there is any question about whether your power supply is adequate for the volt- age, amperes, phase, and frequency specified on the welder nameplate. Also, be sure the planned installation will meet the U.S. National Electrical Code and local code requirements. This welder may be operated from a single phase line or from one phase of a two or three phase line.

2.Models that have multiple input voltages specified on the nameplate (e.g., 208/230) are shipped con- nected for the higher voltage. If the welder is to be operated on lower voltage, it must be reconnected according to the instructions on the inside of the removable panel near the top left side of the rear panel. These instructions are repeated below:

INPUT POWER AND GROUNDING CONNECTIONS

WARNING

ELECTRIC SHOCK can kill.

Do not touch electrically live parts such as output terminals or internal wiring

All input power must be electri-

cally disconnected before proceeding.

IDEALARC SP-255 OCT94

WARNING

Make certain that the input power is electrically disconnected before removing the screw that holds the removable rear panel in place.

3.The 208/230 volt 60 Hz model SP-255 is shipped with a 10 ft. (3.0 m) input cable and plug connected to the welder. A matching receptacle is supplied with the machine. Mount the receptacle in a suit- able location using the screws provided. Be sure it can be reached by the plug on the input cable attached to the welder. Mount with the grounding terminal at the top to allow the power cable to hang down without bending.
