WARNING
Only a qualified electrician should
connect the input leads to the
POWER
Connections should be made in
accordance with all local and
national electrical codes and the connection dia-
grams. Failure to do so may result in bodily injury
or death.
------------------------------------------------------------------------
INPUT CONNECTION
(See Figure A.1)
For Three Phase Input Connect green lead to ground
per National Electric Code. Connect black, grey and
brown leads to power.
Use a three-phrase supply line. A 1.40 inch diameter
access hole with strain relief is located on the case
back. Route input power cable through this hole and
connect L1, L2, L3 and ground per connection dia-
grams and National Electric Code. To access the
input power connection block, remove three screws
holding the access door to the side of the machine.
ALWAYS CONNECT THE POWER WAVE GROUND-
ING LUG (LOCATED AS SHOWN IN FIGURE A.1)
TO A PROPER SAFETY (EARTH) GROUND.

CONSIDERATIONS
Refer to Specification Section for recommended fuse,
wire sizes and type of the copper wires. Fuse the
input circuit with the recommended super lag fuse or
delay type breakers (also called "inverse time" or
"thermal/magnetic" circuit breakers). Choose input
and grounding wire size according to local or national
electrical codes. Using input wire sizes, fuses or cir-
cuit breakers smaller than recommended may result in
"nuisance" shut-offs from welder inrush currents, even
if the machine is not being used at high currents.
INPUT VOLTAGE SELECTION
The POWER WAVE
®
S500CE automatically adjusts to
work with different input voltages. No reconnect switch
settings are required.
WARNING
The
POWER
ON/OFF switch is not intended as a
service disconnect for this equip-
ment. Only a qualified electrician
should connect the input leads to
the
POWER
Connections should be made in accordance with
all local and national electrical codes and the con-
nection diagram located on the inside of the
reconnect access door of the machine. Failure to
do so may result in bodily injury or death.
