Tools Needed:
Y Turn Off welding power source, and
check voltage on input capacitors
according to Section 8-1 before
proceeding.
Y Installation must meet all National
and Local Codes − have only qualified
persons make this installation.
Y Disconnect and lockout/tagout input
power
before
connecting
conductors from unit.
Y Make input power connections to the
welding power source first.
Y Always
connect
green/yellow conductor to supply
grounding terminal first, and never to
a line terminal.

Input Power Conductors (Customer
Supplied Cord)
Select size and length of conductors using
Section 3-10. Conductors must comply with
national, state, and local electrical codes. If

Strain Relief
Install strain relief of proper size for unit and
input conductors. Route conductors (cord)
through strain relief and tighten screws.
S Use large strain relief for input conductor
input
size 8 and larger.
S Use small strain relief with reducing
washers for input conductor size 10.
Connect input conductors as shown in
green
or
illustration.
Route green or green/yellow grounding
conductor through current transducer and
connect to welding power source grounding
terminal first. Then connect input conductors
L1, L2, and L3 to welding power source line
terminals.
Reinstall side panel onto welding power
source.
