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.
