INSTALLATION
POWER WAVE 355
A-2
SELECT SUITABLE LOCATION
The Invertec POWER WAVE 355 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.
• DO NOT MOUNT OVER COMBUSTIBLE SURFACES.
Where there is a combustible surface
directly under stationary or fixed elec-
trical 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
POWER WAVE 355 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 POWER WAVE 355. 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
460VAC. If 460VAC is the desired input, then the
machine may be connected to the power system
without any setup required inside the machine.
SAFETY PRECAUTIONS
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 U.S.National Electrical
Code.
----------------------------------------------------------------------
WARNING
• Initial 200VAC - 415VAC and 575VAC 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
380-575.
• Move the "A" lead to the appropriate terminal.
POWER CORD CONNECTION
A 10 ft. power cord is provided and wired into the
machine. Follow the power cord connection instruc-
tions.
• Incorrect connection may result in equipment
damage.
-----------------------------------------------------------------------

Code.
Connect black and white leads to power.
