A-4 INSTALLATION
POWER WAVE ® R500
A-4
Only a qualified electrician should
connect the input leads to the
POWER WAVE
® R500. Connections
should be made in accordance with
all local and national electrical
codes and the connection diagrams. Failure to do
so may result in bodily injury or death.
------------------------------------------------------------------------
INPUT CONNECTION
(See Figure A.1)
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.
INPUT FUSE AND SUPPLY WIRE
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 ® R500 automatically adjusts to
work with different input voltages. No reconnect switch
settings are required.
The POWER WAVE ® R500 ON/OFF
switch is not intended as a service
disconnect for this equipment. Only
a qualified electrician should con-
nect the input leads to the POWER
WAVE ® R500. Connections should
be made in accordance with all local and national
electrical codes and the connection diagram locat-
ed on the inside of the reconnect access door of
the machine. Failure to do so may result in bodily
injury or death.
