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 mounting
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 hard-
ware and slide forward or backward until the keyway
stops against the mounting hardware.
6. Secure the hardware to the rail.

3.05 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 local 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 illustrations 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.
