equivalent shielding. Flexible helically-wrapped metallic conduit
is generally not suitable.
8. When the welder is enclosed in a metal building, several good
earth driven electrical grounds (as in 5 above) around the
periphery of the building are recommended.
Failure to observe these recommended installation procedures can
cause radio or TV interference problems and result in unsatisfactory
welding performance resulting from lost high frequency power.

INPUT CONNECTION

WARNING
Only a qualified electrician should connect the input leads to
®
the ASPECT 230 DC. 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.
A 10 ft. (2m) power cord is provided and wired into the machine.
For Single Phase Input
Connect green lead to ground per National Electrical Code.
Connect black and white leads to power.
Wrap end of red lead with electrical tape to provide 600V insula-
tion.
For Three Phase Input
Connect green lead to ground per National Electric Code.
Connect black, red and white leads to power.
WARNING
This Class A equipment is not intended for use in residential
locations where the electrical power is provided by the
public low-voltage supply system. There may be potential
difficulties in ensuring electro-magnetic compatability in
those locations, due to conducted as well as radiated
disturbances.

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 circuit 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 Aspect ® 230 DC automatically adjusts to work with the input
voltages listed on the rating plate. No reconnect switch settings are
required.
WARNING
®
The ASPECT 230 DC ON/OFF switch is not intended as a
service disconnect for this equipment. Only a qualified
electrician should connect the input leads to the
®
ASPECT 230 DC. Connections should be made in
accordance with all local and national electrical codes
and the connection diagram located on the inside of the
right case side. Failure to do so may result in bodily injury
or death.

POWER CORD REPLACEMENT

WARNING
Only a qualified electrician should connect the input leads to
®
the ASPECT 230 DC. 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.
If the input power cord is damaged or needs to be replaced, an
input power switch is located in the back of the machine with the
case wraparound removed as shown in Figure A.1.
ALWAYS CONNECT THE GROUNDING LUG (LOCATED AS SHOWN
IN FIGURE A.1) TO A PROPER SAFETY (EARTH) GROUND.
