exists after removal of input power.

SAlways wait 5 minutes after power Is turned off before working on unit.

SCheck input capacitor voltage, and be sure it is near 0 before touching any parts.

Read Owner’s Manual.

Three-Phase Input Connection

802 915-A / Ref. 803 766-A / 218 005-A

! Turn Off welding power source, and check voltage on input capacitors according to Section 7-3before proceeding.

! Installation must meet all National and Local Codes − have only qualified persons make this installation.

!Disconnect and lockout/tagout input power before connecting input conductors from unit.

! Make input power connections to the welding power source first.

applicable, use lugs of proper amperage capacity and correct hole size.

Welding Power Source Input Power Connections

2 Strain Relief

Install strain relief of proper size for unit and input conductors. Route conductors (cord) through strain relief and tighten screws.

SUse large strain relief for input conductor size 8 and larger.

SUse small strain relief with reducing washers for input conductor size 10.

4Green Or Green/Yellow Grounding Conductor

5Disconnect Device Grounding Terminal

6Input Conductors (L1, L2 And L3)

7Disconnect Device Line Terminals

Connect green or green/yellow grounding conductor to disconnect device grounding terminal first.

! Always connect green or green/yellow conductor to supply grounding terminal first, and never to a line terminal.

1Input Power Conductors (Customer Supplied Cord)

Select size and length of conductors using Section 3-12.Conductors must comply with national, state, and local electrical codes. If

Connect input conductors as shown in 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.

Connect input conductors L1, L2, and L3 to disconnect device line terminals.

8 Over-Current Protection

Select type and size of over-current protec- tion using Section 3-12(fused disconnect switch shown).

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