This unit is intended for wall mounting, either recessed into the wall for a flush mounting, or surface mounted on the wall. The unit has built in brackets for mounting. Refer to the UTS Installation section in this manual for details.

The UTS must be installed within one foot of the building circuit breaker panel.

Determine circuit usage

The circuits in the circuit breaker panel should be labeled indicating the load each circuit supports. If the circuits are not labeled, APC recommends working with a licensed electrician to label them.

With the assistance of a licensed electrician:

• determine which circuits support the most vital loads in the home, and should be connected to the UTS.
• determine which lights, appliances, and electrical devices are most essential and should have a backup power supply in the event of a power outage.
• discuss what backup power sources are to be connected to the UTS.
• discuss the capabilities of the backup power sources to be connected to the UTS.

A Quick Install Guide is supplied with the UTS. In this guide find:

• the UTS Wiring Plan table that should be filled in with the electrician. This table will provide an overview of circuits, connected loads, and voltage requirements for use when configuring the UTS.
• the Backup Power Sources Configuration table that should be filled in with the electrician. This table will provide an overview of the backup power sources to be connected, and basic information concerning the power source and configuration of the supporting circuits.

Note: Special note regarding Circuit1.

• Circuit1 loads will receive backup power ONLY from the BACKUP1 (GENERATOR) power source.
• The Convenience Outlet is powered by Circuit1.

The wattage of any load connected to the Convenience Outlet on the UTS is added to the wattage of any load connected to Circuit1.

Backup power sources

Refer to the Specifications table in this manual for information on UTS circuit specifications.

Generators

Review the specifications and other important information for the generator to be connected to the UTS. This information will determine the configuration of the UTS circuits.

Refer to the Specifications table in this manual for compatible generator specifications.

Generator Load Balance

Follow these steps to ensure load balance for the generator. UTS6/UTS6BI/UTS10BI models only

1. Determine the total power rating required if all connected loads were to run continuously and simultaneously.

a. Most home appliances operate for short periods of time. ALM intelligently manages the loads. Refer to the Operation Manual for a complete description of ALM functionality.
b. With ALM enabled, a generator should be capable of delivering approximately 20% or more average energy than with ALM disabled. With ALM enabled, the actual power rating of the generator can be much be less than the total power rating.

1. Estimate the total power for phase 1 and the total power for phase 2. If the total power for the phases are not equal or close to equal, then some of the loads must be swapped between the phases or be moved to another circuit not supported by the generator. This will better balance the power between the phases and ensure optimum generator operation.

Uninterruptible Power Supply (UPS)

A UPS provides:

• backup power during a power outage
• protection for connected loads from possible damage caused by power fluctuations

Refer to the Specifications table in this manual for compatible UPS specifications.
