Lincoln Electric IM983 RED-D-ARC DC655e (CE) - Manual (Page 11)

A-2 INSTALLATION
DC655e (CE) (RED-D-ARC)
A-2
Read entire installation section before starting
installation.
SAFETY PRECAUTIONS
SELECT SUITABLE LOCATION
Place the welder where clean cooling air can freely
circulate in through the front louvers and out through
the rear louvers. Dirt, dust or any foreign material that
can be drawn into the welder should be kept at a
minimum. Failure to observe these precautions can
result in excessive operating temperatures and
nuisance shut-downs.
ELECTROMAGNETIC COMPATIBILITY (EMC)
The EMC classification of the DC655e (CE) is Industrial,
Scientific and Medical (ISM) group 2, class A. The DC655e
(CE) is for industrial use only. (See prints L10093-1, -2
Safety Pages in the front of Instruction Manual for further
details).
Locate the DC655e (CE) away from radio controlled
machinery. The normal operation of the DC655e (CE)
may adversely affect the operation of RF controlled equip-
ment, which may result in bodily injury or damage to the
equipment.
STACKING
The DC655e (CE) may be stacked three-high provid-
ed the bottom machine is on a stable, hard, level sur-
face. Be sure that the two pins in the roof fit into the
slots in the base of the DC655e (CE) above it.
TILTING
Do not place the machine on a surface that is inclined
enough to create a risk of the machine falling over.
ELECTRICAL
INPUT CONNECTIONS
Before installing the machine check that the input sup-
ply voltage, phase, and frequency are the same as the
voltage, phase, and frequency as specified on the
welder nameplate.
Use input wire sizes that meet local electrical codes or
see the Technical Specifications page in this manu-
al.
Input power supply entry is through the hole in the
Case Back Assembly. See Figure A.1 for the location
of the machine’s input cable entry opening, Input
Contactor (CR1), and reconnect panel.
FUSE AND WIRE SIZES
Protect the input circuit with the super lag fuses or
delay type circuit breakers listed on the Technical
Specifications page of this manual for the machine
being used. They are also called inverse time or ther-
mal/magnetic circuit breakers.
DO NOT use fuses or circuit breakers with a lower
amp rating than recommended. This can result in
“nuisance” tripping caused by inrush current even
when machine is not being used for welding at high
output currents.
GROUND CONNECTION
Ground the frame of the machine. A ground
terminal marked with the symbol ( ) is located inside
the case back of the machine near the input contactor.
Access to the input box assembly is at the upper rear
of the machine. See your local and national electrical
codes for proper grounding methods. Use grounding
wire sizes that meet local electrical codes or see the
Technical Specifications page in this manual.
ELECTRIC SHOCK can kill.
• Only qualified personnel should
perform this installation.
• Turn the input power OFF at the discon-
nect switch or fuse box before working on
this equipment.
• Turn the Power switch on the DC655e
(CE) “OFF” before connecting or discon-
necting output cables, wire feeder or
remote connections, or other equipment.
• Do not touch electrically hot parts.
• Always connect the DC655e (CE) ground-
ing terminal (located on the welder near
the reconnect panel) to a good
electrical earth ground.
