!
Installation must meet all National and
Local Codes
−
have only qualified per-
sons make this installation.
!
Disconnect and lockout/tagout input
power before connecting input
conductors from unit. Follow estab-
lished procedures regarding the in-
stallation and removal of lockout/
tagout devices.
!
Make input power connections to the
welding power source first.
!
Always connect green or green/yellow
conductor to supply grounding
terminal first, and never to a line
terminal.
NOTICE
−
The Auto-Line circuitry in this unit
automatically adapts the power source to the
primary voltage being applied. Check input
voltage available at site. This unit can be con-
nected to any 3-phase input power between
230 and 575 VAC without removing cover to
relink the power source.
See rating label on unit and check input volt-
age available at site.
1
Input Power Conductors (Customer
Supplied Cord)
Select size and length of conductors using
Section 5-8. Conductors must comply with
national, state, and local electrical codes. If
applicable, use lugs of proper amperage
capacity and correct hole size.
