About this product
The APC® by Schnei d er El ec tr i c Universal Transfer Switch (UTS) is a fully automatic transfer switch for use in optional
standby syst ems in homes or s mall bus ines ses. This unit prov ide s safe, conveni ent powe r for up to ten circuit s in th e home
or office. Power is derived from one or two independe nt bac kup sources. Backup sourc es being a generator , an
uninterruptible power supply (UPS), a solar inverter, or another alternative energy source.
When connected to home appliances, computers, or entertainment equipment the backup power sources provide power
during uti lity powe r out ages. Whe n a UPS is us ed in t he conf igura tion, connec ted eq uipmen t (load) , c an be pro tected fro m
utility br ownouts, sags, surges, and power outages. The UPS provides continuous power from the internal batter y until
utility power ret urns to safe levels or the batter y is fully discharged .
The models supported by thi s manual vary in appearance and have
some variation in function.
Individual model f unctionality will be addressed in this manual.

Press the System Setup button located on the front of the UTS to enter system setup mode and to navigate through the
system setup options.
Use the down/u p arrow buttons to navigate through the configuration options and to change values displayed on the LCD.
Note: The settings and values sel ec ted will change immediately after an arrow button is pressed.
The LCD will revert back to the starting display message after 30 seconds with no activity.
Bypass Mode
Use the up arrow key to select NO, indicating that bypass mode is disabled or YES,
enabling bypass mode on the UTS.
In bypass mode, all circuits are powered by the utility power source. Backup power
sources are not used to power loads regardles s of the status or quality of the primary
utility power source.
Warning: Changing bypass mode settings while connected to utility power will cause all connected
loads to be momentarily disconnected.
When bypass mode is enabled, overload prote ction is provided. Hig h and low voltage protect ion is not
available when bypass mode is enabled.
Load Shedding
Use the down/up ar row ke ys to se lect ON, indica ting th at load s hedding is enabl ed o r
OFF, to disable load sh edding.
The UTS provides inte lligent load manag ement, defined by APC as adaptive load
management (ALM).
When a backup power source is nearing an overload condition, ALM intelligence sheds (drops) select loads and then
reconnects the loads when adequate power becomes available. ALM selects the most suitable loads to drop and reconnect
at any given time minimizing overall load disruption, and maximizing backup power capability.
When load shedding is enabl ed (ALM is on), the average en ergy output of a backup power source can increase by 20% or
more. This allows more loads to be connected without overloading or stalling a backup power source.
When load shedding is disabled (ALM is off), overload co nditions can occur causing a gene rator to stall, a circuit breaker
to trip, or loads may experience severe low vol tage conditions.
Load Shedding must be enabled for each circuit to be set individually for specific maximum time off and minimum tim e
on. Refer to Circuit Maximum Time Off and Minimum Time On section in this manual.
Voltage Se nsit ivity
Use the down/up arrow keys to select High, Medium, o r Low voltage sensitivity.
The voltage sen si tivity level determines how the UTS reacts to voltage fluctuations.
Medium voltage sensitivity setting is a suitable setting for most situat ion s.
High voltage sensitivity setting is rec ommended only for loads tha t are very sensitive to vol tage fluctuations .
Low voltage sensitivity setting is recommended for loads that can tolerate most power fluctuations.

WARNING: Home generator backup systems should be installed by a qualified electrician.
Locate the generator outside a building and at least 10 feet away from buildings, wind ows, and doors.
Failure to fol low this safety rule may result in illness or death from breath ing carbon monoxide.
The generator must have three to four feet of space around all sides and the top to ensure proper
ventilation.
Locate the generator on a dry, level sur face protected fr om rai n and excess ive dust.
Fuel for gas operated generators must be stored in approved containers, and in well ventilated
conditions.
Refer to the generator user documentation for additional safety precautions.
For generators featuring automatic st art, use the AUTO settin g.

The factory default s etting for the backup power source is GEN (ge nerator). Use the down/up a rrow keys to establish the
backup power source for a selec ted circuit.
GEN-backup power source will be a connected genera tor.
UNINTERRUPTIBLE-there is continuous backup power supplied by a UPS. Utility power flows into the UPS and from
the UPS to the connected loa d. This provides power and prot ec tion for the load during any utility power fluctuation.
NONE-there will be no backup power source available.
EITHER-bac kup power source will be either a conne cted generator or a UPS.
UPS-backup power source will be a connected UPS.
Note: Backup power source availability varies for some circuits.
The UPS and EITHER backup power source options are not available for:
• circuit1 on all units
• the designated 240 V circuits on the UTS6BI or the UTS10BI
Dela yable Circuits
The factory defaul t se tting is NO. Setting a circuit to YES, enables the UTS to run
ALM for the individual circuit selected.
The UTS provides inte lligent load manag ement, defined by APC as adaptive load
management (ALM).
The Delayable Circuits setup option works in conj unction with Load Shedding and Ti me M ana ge me nt. Th e Delayable
Circuits setup option require s that both Load Shedding and Time Man agement under Sy stem Se tup, be se t to ON. Once
Load Shedding and Time Management have been enabled each circuit can be individually set to YES enabling the
Delayable Circuits feature.
• Load Shedding is us ed with time management to ensure loads receive ade quate power over extended periods
of time. When a backup power source is nearing an overload condition, ALM intelligenc e sheds (drops),
select loads and then reconnects the loads when adequate power becomes available. ALM selects the most
suitable loads to drop and reconnect at any given time minimizing overall load disruption, and maximizing
backup power capability.
• When load shedding is disa bled (ALM is off), overload conditions can occur causing a generator to stall, a
circuit breaker to trip, or loads may experience severe low voltage conditions.
• Time Manageme nt is used with load shedding to ensure loads receive adequa te power over extended periods
of time. There are two time management settings, Maximum Off and Minimum On. Th ese can be set fo r
each circuit th rough Ci rcuit Setup. When this f eatu r e is on , ti me manage me nt ensur es t hat loa ds are no t s hed

Minimum On controls the amount of time a circuit must receive power before it is
eligible to be she d to prevent an overload con dition.
It is recommended that a refrig era tor should have a Minimum On setting of 45

Troubleshooting
Use this chart to solve mi nor U TS pr oblems.
Refer to www.apc.com for assistance with complex UTS problems.
Problem and Possible Cause Solution
Problem: While operating on utility power the UTS repeatedly drops some connected loads
Cause: One or more circuits may be in
Security Mode.
Cause: The LCD displays a message
indicating th at one or more cir cuits may
be experiencing an overload condition.
Problem: While operating on backup power the UTS repeatedly drops some connected loads
Cause: ALM may be enabled. • Disable ALM using the System Setup button.
Cause: The circuit may be incorrectly
configured as delayabl e.
Cause: The circuit may be incorrectly
configured for MAX OFF and MIN
ON.
Cause: The generator power rating is
set too low.
Problem: While operating on backup power the generator stalls, shuts down or the circuit breaker trips
repeatedly
Cause: The generator power rating is
set too high causing an overload
condition.
Using the Circuit S etup button on the UTS, check to verify the status of
Security Mode.
Reduce the load on th e affe ct ed circuit s or ha v e a qu a li f ied elect r ic ia n
upgrade the cir cuit amp capacity.
NOTE: When AL M is disable d overload co nditions can occur causi ng a
generator to stall, a circuit breaker to trip, or loads may experience
severe low voltage conditions.
Use the Circuit Setup button to navigate to CKT DELAYABLE screen for
the circuit affected. Disable the circuit delaya ble option, (select NO). This
disables ALM for that circuit. Repea t this process for all circuits affe ct ed.
Change the parameters for Maximum OFF and Minim um ON times, for
circuits supporting loads being adversely affected by drops.
