SAFETY PRECAUTIONS Read
this
entire installation section before you start installa-
tion.
ELECTRIC SHOCK can kill.
• Turn off the power source at the
disconnect switch before connect-
ing or working inside of the equip-
ment.
• Only a qualified electrician should
install and connect the STT ®
Module.

ELECTROMAGNETIC COMPATIBILITY
(EMC)
The EMC classification of the POWER WAVE ® STT ®
MODULE (CE) is Industrial, Scientific and Medical
(ISM) group 2, class A. The POWER WAVE
® STT ®
MODULE (CE) is for industrial use only. (See print
L10093 for further details).
Locate the STT ® Module away from radio controlled
machinery. The normal operation of the STT ® Module
may adversely affect the operation of RF controlled
equipment, which may result in bodily injury or dam-
age to the equipment.
LOCATION AND MOUNTING
(See Figure A.1)
Mount the STT Module directly to the bottom of a
compatible Power Wave “S” series power source uti-
lizing the quick lock mechanism as shown. The STT
Module will operate in harsh environments and can be
used outdoors. 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
circulation of clean air such that movement into
and out of the louvers will not be restricted.
• Dirt and dust that can be drawn into the machine
should be kept to a minimum. The use of air filters
on the air intake is not recommended because nor-
mal air flow may be restricted. Failure to observe
these precautions can result in excessive operat-
ing temperatures and nuisance shutdown.
• Keep the machine dry. Shelter from rain and snow.
Do not place on wet ground or in puddles.
• Do not mount the Power Wave “S” series power
source and STT Module combination over com-
bustible 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 .060” (1.6mm) thick, which shall
extend not less than 5.90” (150mm) beyond the
equipment on all sides.

CONTROL CABLE CONNECTIONS
General Guidelines
Genuine Lincoln control cables should be used at all
times (except where noted otherwise). Lincoln cables
are specifically designed for the communication and
power needs of the Power Wave systems. Most are
designed to be connected end to end for ease of
extension. Generally, it is recommended that the total
length not exceed 100 feet (30.5 m). The use of non-
standard cables, especially in lengths greater than 25
feet, can lead to communication problems (system
shutdowns), poor motor acceleration (poor arc start-
ing), and low wire driving force (wire feeding prob-
lems). Always use the shortest length of control cable
possible, and DO NOT coil excess cable.
