INPUT POWER CONNECTIONS

The frequency of the input power can be 50 or 60 Hz, and is not related to the output frequency

CAUTION: The Input is Electrically Isolated from the output. It is necessary to connect the input using one of the following four methods.

A. SINGLE PHASE 220V INPUT

This connection is usually used in 50Hz countries where a neutral is normally available.

B. SPLIT PHASE 220V INPUT

This connection is usually used in 60Hz countries where a 220V line is not normally available, and where the input amperage makes using 120V inconvenient.

C. SINGLE PHASE 120V INPUT

D. THREE PHASE 120/208 VAC USING LINE TO LINE INPUT

To be used if the 120V line to neutral connection is limited by the amperage available.
