!
Installation must meet all National
and Local Codes − have only qualified
persons make this installation.
!
Disconnect and lockout/tagout input
power before connecting input con-
ductors from unit. Follow established
procedures regarding the installation
and removal of lockout/tagout de-
vices.
!
Make input power connections to the
welding power source first.
!
Always connect green or green/yel-
low conductor to supply grounding
terminal first, and never to a line ter-
minal.
.
The circuitry in this unit automatically
adapts the power source to the primary
voltage being applied. Check input volt-
age available at site. This unit can be
connected to either 460 or 575 VAC input
power.
See rating label on unit and check input volt-
age available at site.

Input Power Conductors (Customer
Supplied Cord)
Select size and length of conductors using
Section 5-3. Conductors must comply with
national, state, and local electrical codes. If
applicable, use lugs of proper amperage
capacity and correct hole size.
