Installation

3.7 Connecting Mains and Load

When connect the mains supply to the UPS refer to Figures 6 through 8. Choose the connection

method according to the input supply characteristics. Connections must meet these requirements:

• The installer must provide circuit breaker protection according to local codes. The mains discon-

nect should be within sight of the UPS or have an appropriate lock-out. Maintain service space

around the UPS or use flexible conduit.

• The installer must provide output distribution panels, circuit breaker protection, or emergency

disconnect switches according to local codes. Output circuits must not share a common conduit

with input circuits or any other wiring.

• The utility may be derived from a single-phase or three-phase source.
