HARDWIRE CONNECTIONS

Electrical Installation Considerations

! CAUTION

This UPS must be installed by competent electrical personnel and wired in accordance with local/national electrical codes.

! CAUTION

The utility input supply to the POD must be protected by a branch rated circuit breaker. The UPS output must also be protected with a circuit breaker connected to the load, rated to carry the input current, and be capable of breaking the maximum expected short circuit current of this branch circuit. The breaker is to be mounted within 6 feet of the POD and be readily accessible to the operator. Refer to Table 1 for breaker specification.

! CAUTION

Before installing, open all branch circuit power at the nearest disconnect, turn UPS off, and disconnect all cords to and from the UPS.

The front and bottom of the POD provide alternate conduit entry points for both the UTILITY and LOAD connections.
