SECTION 3 SYSTEM:
INSTALLATION
3.01 Unpacking
1. Use the packing lists to identify and ac-
count for each item.

damage. If damage is evident, contact
your distributor and / or shipping company

and serial numbers, purchase date and ven-
dor name, in the information block at the
front of this manual.
3.02 Lifting Options
The Power Supply includes hand holds in the
front and rear panels for hand lifting only. Be
sure unit is lifted and transported safely and se-
curely.

FALLING EQUIPMENT can cause serious
personal injury and can damage equipment.
• Only persons of adequate physical strength
should lift the unit.
• Lift unit by the handles, using two hands.
Do not use straps for lifting.
• Use optional cart or similar device of ad-
equate capacity to move unit.

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 rm 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 thick-
ness 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 mount-
ing 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 exten-
sion 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
230Volt input power cable wired to the input
contactor in the single - phase conguration.
The following illustrations and directions are for
changing that conguration to a different voltage
and or to three - phase operation or back again if a
change had already been made.
