COnneCtiOn tO mains

The KempGouge™ ARC 800 gouging power source is connected to a 400-V three-phase

network. The machine is delivered without a connection cable. The cable can be ordered

separately in lenght of 5 or 10 metres (see Ordering numbers).
Before use, check the connection cable and install a mains plug. If the cable does not comply

with the local electrical regulations, replace it with a compliant cable. For more information,

see the section Technical specifications.

NOTE!

the connection cable or plug may be installed or replaced by only an electrical contractor or

installer authorised to perform such operations.

Connecting the connection cable

Remove the right side plate. Be carefull when you unscrew the mounting screws of the

plastic edge, cause retaining nuts come out easily.

Pass the cable to the machine through the inlet ring at the rear of the machine, and

secure the cable with a cable clamp. Remember to use isolation between the cabel and

the cable clamp.

Connect the leads to the connectors as seen in the picture.

Fasten the side plate.

distributiOn netwOrK

All regular electrical devices without special circuits generate harmonic currents into

distribution network. High rates of harmonic current may cause losses and disturbance to

some equipment. This equipment complies with IEC 61000-3-12 provided that the short-

circuit power Ssc is greater than or equal to 7.6 MVA at the interface point between the user's

supply and the public supply network. It is the responsibility of the installer or user of the

equipment to ensure, by consultation with the distribution network operator if necessary, that

the equipment is connected only to a supply with a short-circuit power Ssc greater than or

equal to 7.6 MVA.
