INSTALLATION
MACHINE GROUNDING AND HIGH FRE-
QUENCY INTERFERENCE PROTECTION
The Capacitor Discharge Circuit used in the high fre-
quency generator, may cause many radio, TV and
electronic equipment interference problems. These
problems may be the result of radiated interference.
Proper grounding methods can reduce or eliminate
radiated interference.
The Invertec V205-T AC/DC has been field tested
under recommended installation conditions. It com-
plies with FCC allowable limits for radiation.
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 pos-
sible 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 pos-
sible and as close together as possible. Lengths
should not exceed 25 ft (7.6m). Tape the electrode
and work leads together into one bundle when prac-
tical.
Read entire installation section before starting
installation.
Safety Precautions
------------------------------------------------------------
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 front 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 V205-T AC/DC can
not be stacked.
TILTING
Place the machine directly on a secure, level surface.
The machine may topple over if this procedure is not
followed.
ENVIRONMENTAL AREA
Keep the machine dry. Do not place it on wet ground or
in puddles.
ELECTRIC SHOCK can kill.
Only qualified personnel should per-
form this installation.
• Turn the input power OFF and unplug
the machine from the receptacle
before working on this equipment.
Allow machine to sit for 5 minutes
minimum to allow the power capac-
itors to discharge before working
inside this equipment.
Insulate yourself from the work and ground.
Always wear dry insulating gloves.
Always connect the V205-T to a power supply
grounded according to the National Electrical Code
and local codes.
