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 move-
ment 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 Opening the Contactor Cover
The input power cord is connected to the main contactor, the
contactor is located inside a box with a snap on cover. The cover
is held in place with two or more snap lock tabs. To remove
the cover release the front latch and tilt the cover up about ½
inch. Then squeeze both sides of the cover and lift it straight
up. See the Primary Input Power Connections section for the
necessary changes to the Contactor. Remember to replace the
Contactor Cover when the changes are complete.
