Safety Precautions

WARNING

ELECTRIC SHOCK can kill.

•Only qualified personnel should perform this installation.

•Turn the input power OFF at the disconnect switch or fuse box before working on this equipment.

•Do not touch electrically hot parts.

•Always connect the V200-T to a power sup- ply grounded per the National Electrical Code and any local codes.

SELECT SUITABLE LOCATION

The Invertec will operate in harsh environments. Even so, it is important that simple preventative measures are followed in order to assure long life and reliable operation.

•The machine must be located where there is free cir- culation of clean air such that air movement in the back and out the sides will not be restricted.

•Dirt and dust that can be drawn into the machine should be kept to a minimum. Failure to observe these precautions can result in excessive operating temperatures and nuisance shutdown.

STACKING

The Invertec V200-T cannot be stacked.

LIFTING AND MOVING

The Invertec V200-T has a lift handle on the top of the case and also comes with a lift-carrying strap for con- vience.

TILTING

Place the machine directly on a secure, level surface. The machine may topple over if this procedure is not followed.

ENVIRONMENTAL RATING

•The machine has a protection rating of IP23. Keep the machine dry when possible. Do not place it on wet ground or in puddles.

MACHINE GROUNDING AND HIGH FRE- QUENCY INTERFERENCE PROTECTION

The welder must be grounded. See your local and national electrical codes for proper grounding methods.

The high frequency generator, being similar to a radio transmitter, can be blamed for radio, TV and electron- ic equipment interference problems. These problems may be the result of radiated interference. Proper grounding methods can reduce or eliminate radiated interference.

Radiated interference can develop in the following four ways:

1.Direct interference radiated from the welder.

2.Direct interference radiated from the welding leads.

3.Direct interference radiated from feedback into the power lines.

4.Interference from re-radiation of “pickup” by ungrounded metallic objects.

Keeping these contributing factors in mind, installing equipment per the following instructions should mini- mize problems.

1.Keep the welder power supply lines as short as possible and enclose as much of them as possible in rigid metallic conduit or equivalent shielding for a distance of 50 feet (15.2m). There should be good electrical contact between this conduit and the welder case ground. Both ends of the conduit should be connected to a driven ground and the entire length should be continuous.

2.Keep the work and electrode leads as short as possible and as close together as possible. Lengths should not exceed 25 ft (7.6m). Tape the leads together when practical.

3.Be sure the torch and work cable rubber coverings are free of cuts and cracks that allow high frequen- cy leakage.

4.Keep the torch in good repair and all connections tight to reduce high frequency leakage.

5.The work piece must be connected to an earth ground close to the work clamp, using one of the following methods:
