3.03 Power Supply location and
Mounting
NOTE
It is recommended that the unit be secured to a
suitable surface using the mounting rails.
1. First choose an appropriate location for mount-
ing the power supply. Choose one that allows
for free movement of torch leads, complies
with ventilation per section 2.04 and provides a
safe firm surface where the unit can be secured.
2. Place the unit in the desired position and mark
where the four keyway holes in
the mounting rails touch.
3. Remove the unit and using these markings,
prepare holes for mounting hardware.
4. Insert proper hardware. If using hardware
that screws into the mounting surface, leave
all four loose enough for the thickness of the
rail to slide under the head and washer if used.
5. Lower the power supply over the mounting
hardware and slide forward or backward
until the keyway stops against the mounting
hardware.
6. Secure the hardware to the rail.
3.04 Primary Input Power Connections
CAUTION
Check your power source for correct voltage
before plugging in or connecting the unit. Check
the Voltage Selector at the rear of the unit for
correct setting before plugging in or connecting
the unit. The primary power source, fuse, and
any extension cords used must conform to lo-
cal electrical code and the recommended circuit
protection and wiring requirements as specified
in Section 2.
Most units are shipped from the factory with a 230 Volt
input power cable wired to the input contactor in the
single - phase configuration. The following illustra-
tions and directions are for changing that configuration
to a different voltage and or to three - phase operation
or back again if a change had already been made.
A. Cover Removal
1. Remove the upper and lower screws which
secure the cover to the main assembly. Do not
loosen the lower screws inside the cut out slots
in the bottom of the cover.
