!
Turn Off welding power source, and
check voltage on input capacitors
according to Section 8-9 before
proceeding.
!
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.
.
The Auto-Line circuitry in this unit
automatically links the power source to the
primary voltage being applied. Check input
voltage available at site. This unit can be
connected to any input power between 208
and 575 VAC without relinking 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 4-6. Conductors must comply with
national, state, and local electrical codes. If
applicable, use lugs of proper amperage
capacity and correct hole size.
