!

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 con-

 

ductors from unit.

!

Make input power connections to the

 

welding power source first.

!

Always connect green or green/yellow

 

conductor to supply grounding termi-

 

nal first, and never to a line terminal.

.The 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 connected to either 400 or 460 VAC input power.

See rating label on unit and check input volt- age available at site.

1Input Power Conductors (Customer Supplied Cord)

Select size and length of conductors using Section 4-4. Conductors must comply with national, state, and local electrical codes. If applicable, use lugs of proper amperage capacity and correct hole size.

Welding Power Source Input Power Con- nections

2 Strain Relief

Route conductors (cord) through strain relief and tighten screws.

3Machine Grounding Terminal

4Green Or Green/Yellow Grounding Conductor

Connect green or green/yellow grounding conductor to welding power source grounding terminal first.

5Welding Power Source Line Terminals

6Input Conductors L1 (U), L2 (V) And L3

(W)

Connect input conductors L1 (U), L2 (V) and L3 (W) to welding power source line terminals.

Close and secure access door on welding power source.

Disconnect Device Input Power Connec- tions

7Disconnect Device (switch shown in OFF position)

8Disconnect Device (Supply) Grounding Terminal

Connect green or green/yellow grounding conductor to disconnect device grounding ter- minal first.

9 Disconnect Device Line Terminals

Connect input conductors L1 (U), L2 (V) And L3 (W) to disconnect device line terminals.

10 Over-Current Protection

Select type and size of over-current protection using Section 4-4(fused disconnect switch shown).

Close and secure door on line disconnect de- vice. Remove lockout/tagout device, and place switch in the On position.
