SAFETY PRECAUTIONS

WARNING
ELECTRIC SHOCK can kill.
• TURN THE INPUT POWER OFF AT
THE DISCONNECT SWITCH BEFORE
ATTEMPTING TO CONNECT OR DIS-
CONNECT INPUT POWER LINES, OUTPUT
CABLES, OR CONTROL CABLES.
• Only qualified personnel should perform this
installation.
• Connect the green/yellow lead of the power
cord to ground per appropriate National
Electrical Code.
----------------------------------------------------------------------

SELECT SUITABLE LOCATION

The Invertec ® V350-PRO (CE) will operate in harsh
environments. Even so, it is important that simple pre-
ventative 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, out the sides and bottom 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.
• Keep machine dry. Shelter from rain and snow. Do
not place on wet ground or in puddles.
CAUTION
• DO NOT MOUNT OVER COMBUSTIBLE SURFACES.
Where there is a combustible surface directly
under stationary or fixed electrical equipment,
that surface shall be covered with a steel plate at
least .06"(1.6mm) thick, which shall extend not
less than 5.90"(150mm) beyond the equipment on
all sides.
------------------------------------------------------------------------

STACKING

Invertec V350-PRO (CE) cannot be stacked.

TILTING

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

INPUT AND GROUNDING CONNECTIONS

• Only a qualified electrician should connect the
Invertec ® V350-PRO (CE). Installation should be
made in accordance with the appropriate National
Electrical Code, all local codes and the information
detailed below.
• When received directly from the factory, multiple
voltage machines are internally connected for
440VAC. If 440VAC is the desired input, then the
machine may be connected to the power system
without any setup required inside the machine.
INSTALLATION
• Initial 200VAC - 415VAC operation will require an
Input voltage panel setup.
• Open the access panel on the rear of the machine.
• For 200 or 230: Position the large switch to 200-230.
For higher voltages: Position the large switch to 380.
• Move the "A" lead to the appropriate terminal.

POWER CORD CONNECTION

A 5 meter power cord is wired into the machine.
Follow the power cord connection instructions.
• Incorrect connection may result in equipment
damage.
