Use the following procedure to connect utility power and load to the

UPS:

1. Verify that the electrical connections to the installation site have

been properly installed. Compare the circuit breaker ratings and

cable sizes to the ones shown in the terminations table on

page 24.

2. A user-supplied, readily-accessible, disconnection device must

be incorporated in both the input and output wiring (see the

following breaker ratings).
