SAFETY PRECAUTIONS

WARNING

ELECTRIC SHOCK can kill.

•Only qualified personnel should per- form this installation.

•Disconnect input power by removing plug from receptacle before working inside INVERTER ARC™ 230. Allow machine to sit for 5 minutes mini- mum to allow the power capacitors to discharge before working inside this equipment.

•Insulate yourself from the work and ground.

•Always wear dry insulating gloves.

•Always connect the INVERTER ARC™ 230 to a power supply grounded according to the National Electrical Code and local codes.

SELECT SUITABLE LOCATION

This machine can operate in harsh environments. However, it is important that simple preventative measures are followed to assure long life and reliable operation:

•This machine must be located where there is free circulation of clean air without restrictions for air movement to and from the air vents. Do not cover the machine with paper, cloth or rags when switched on.

•Dirt and dust that can be drawn into the machine should be kept to a minimum.

•This machine has a protection rating of IP21S. Keep it dry and do not place it on wet ground or in puddles. Do not use in wet or damp locations. Store indoors.

•Locate the machine away from radio controlled machinery. Normal operation may adversely affect the operation of nearby radio controlled machinery, which may result in injury or equipment damage. Read the section on electromagnetic compatibility in this manual.

•Do not operate in areas with an ambient tempera- ture greater than 40°C.

STACKING

The INVERTER ARC™ 230 cannot be stacked.

TILTING

Place the machine directly on a secure, level surface. Do not place or operate this machine on a surface with an incline greater than 15° from horizontal. The machine may topple over if this procedure is not fol- lowed.

INPUT CONNECTIONS

GROUND CONNECTION

The frame of the welder must be ground- ed. A ground terminal marked with the symbol is located on the under panel for this purpose. See your local and national electrical codes for proper grounding methods.

WARNING

A grounding conductor is supplied in the input cord, it is important that the supply receptacle ground is connected.

•The welding power source supply cable is pro- vided with a green or yellow/green wire that must ALWAYS be earthed. This green or yellow/green wire must NEVER be used with other voltage conductors.

•Only install plugs that conform with safety regu- lations.

------------------------------------------------------------

INPUT POWER CONNECTION

Check the input voltage, phase, and frequency sup- plied to this machine before turning it on. The allow- able input voltage is indicated in the technical specifi- cation section of this manual and on the rating plate of the machine. Be sure that the machine is grounded.

Make sure the power available at the input connection is adequate for normal operation of the machine. The fuse rating and cable sizes are both indicated in the technical specification section of this manual.

Fuse the input circuit with time delay fuses marked “D” or delay type(1) circuit breakers. Using fuses or circuit breakers smaller than recommended may result in “nuisance” shut-offs from welder inrush currents even if not welding at high currents.

(1)Also called “inverse time” or “thermal/magnetic” circuit breakers. These circuit breakers have a delay in tripping action that decreases as the magnitude of the current increases.

The INVERTER ARC™ 230 is recommended for use on an individual branch circuit.
