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.
2. 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.
Installation
Adhere to all national and local electrical codes.
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 tabs for mounting. Spacers are supplied in the accessories kit, for use in installations where the wall
will have wallboard applied after the UTS installation is complete.
Caution: The UTS must be installed within one foot of the building circuit breaker panel. If the UTS must
be located further than one foot from the circuit breaker panel, a licensed electrician must extend the wiring
using standard electrical wiring conduit and junction boxes.
