YInstallation must meet all National and Local Codes − have only quali- fied persons make this installation.

YDisconnect and lockout/tagout in- put power before connecting input conductors from unit.

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

.The Auto-Line circuitry in this unit au- tomatically adapts the power source to the primary voltage being applied. Check input voltage available at site. This unit can be connected to any in- put power between 120 and 460 VAC without removing cover to relink the power source.

For Three-Phase Operation

1Input Power Cord.

2Disconnect Device (switch shown in the OFF position)

3Green Or Green/Yellow Grounding Conductor

4Disconnect Device Grounding Terminal

5Input Conductors (L1, L2 And L3)

6Disconnect Device Line Terminals

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

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

7 Over-Current Protection

Select type and size of over-current protection using Section 4-9(fused dis- connect switch shown).

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