SAFETY PRECAUTIONS

ELECTRIC SHOCK can kill.

• Do not touch electrically live

parts such as output terminals or
internal wiring.

• Insulate yourself from the work

and ground.

• Turn power switch off before connecting or discon-

necting cables or connections.

• Always connect grounding terminal to a proper elec-

trical earth ground.

Only qualified personnel should install, use, or ser-
vice this equipment.

LOCATION AND VENTILATION

Place the IDEALARC CV-400 where clean, cooling air
can flow freely in through the front louvers and out
through the rear louvers. Keep dust, dirt, and other for-
eign materials that can be drawn into the machine to a
minimum. Failure to observe these precautions can
lead to excessive operating temperatures and nuisance
shut-downs.

THE CV-400 carries an IP-21 environmental rating.
Locate indoors or shelter from falling water such as rain.

LIFTING

FALLING EQUIPMENT can cause injury.

• Do not lift this machine using the lift

hook if it is equipped with a heavy
accessory such as a trailer or a gas
cylinder.

• Lift only with equipment of adequate

lifting capacity.

• Be sure the machine is stable when lifting.

• Do not stack more than three high.

• Do not stack the CV-400 on top of any other machine.

The IDEALARC CV-400 weighs 357 pounds (162 kilo-
grams). A permanent lift hook is located at the top of
the machine, positioned at the center of gravity for sta-
ble lifting.

STACKING

IDEALARC CV-400s may be stacked three high. The
bottom machine must be on a stable, hard, level sur-
face capable of supporting the weight of up to three
machines (1071 pounds/486 kilograms). Be sure that
the two holes in the top front corners of the bottom
machine line up with the holes in the base rails of the
machine above. Fasten the machines together with
5/16" bolts, lockwashers, and nuts through these holes.
The lift hook is positioned so that it fits without interfer-
ence under the base of the second machine.

TILTING

Place the machine on a secure, level surface. Any sur-
faces you place it on other than the ground must be
firm, non-skid, and structurally sound.

ELECTRICAL INPUT CONNECTIONS

Be sure the voltage, phase, and frequency of the input
power is as specified on the rating plate, located on the
case front control panel. See

Figure A.1.

Input supply line entry is through a hole in the case rear
top panel. A removable door covers the input connec-
tion box, which contains the input contactor (CR1) and
reconnect panel assembly for multiple voltage connec-
tion. Input power is connected to the three line termi-
nals on the input contactor. See

Figure A.2.
