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.

Safety and Regulatory Information - save this information
Read the Operation Manual before operating the UTS.
Read, understand, and follow the Safety Precautions in this manual.
Safety Precautions
• Adhere to all national and local electrical codes when installing, configuring and operating the UTS.
• Installation of the UTS must be performed by a qualified electrician.
• Prior to installing the UTS have a qualified electrician check that the wiring in the home or office meets all
local and national electrical cod es.
• This unit must be conne cte d to a properly grounded utility power source.
• Do not install or operate this unit near a source of water or in an environment where the rel ative humidity
could exceed 95% (non-condensing).
• DO NOT operate a generator inside a building. Operating a generator inside a building ca n cau se death by
asphyxiation.
• DO NOT allow the tot al lo ad conne cte d to the UTS to exceed the limits list ed in the Specifications sectio n of
the Site Preparation and Ins tallation Guide.
• There are no user serv iceable components in this unit. Removing the cover from this unit by unqualified
persons can prese nt a shock hazard and may void the warranty.
• Periodically i n spect all po w er cords to en sure:
– secure co n n ect i on s
– proper routing to ensure cords are not pinched, frayed, or stepped on
• If the UTS is damaged, disconnect the main circuit breaker and contact APC at www.apc.com.
Warning: Stop using the unit immediately i f any of the following conditions arise.
•Conduit or receptacles have been damaged
•Objects have fallen into the unit
•Liquid has spilled into the unit
•The unit has been exposed to rain

• provides UPS backup for uninterrupted operation
• provides backup power until the generator comes on line
Provides automatic shut off (referred to as load shedding), of se lect circuits during blackout
conditions
• prevents power surg es and ove rload conditions from st alling a generator, or tripping circuits
• increases generator ef ficiency by 20% or more during prolonge d power outages
• automatically reconnects loads once the overload conditions have been corrected
Provides automatic transfer of select loads between a generator and a UPS
• minimizing power interruptions due to overload conditions
• maximizing power availability
Time management feature sets maximum and minimum times for ALM to run
Refer to the Configuration and Setup section in this manual for detailed functionality
Settings determine how the UTS reacts to momentary power fluctuations
MEDIUM - factory default
LOW - useful when frequent, small power fluctuations DO NOT require UTS intervention
HIGH - recommended ONLY for loads that are very sensitive to small, brief power
fluctuations
When security mode is set to ON, the UTS automatically cycles power to circuits at a rate of
two hours on and two hours off
Recommended for use on strategic light circuits during vacations
Bypass Mode
Liquid Crystal Display
(LCD)
Automatic Start/Stop
Operation
During bypass mode operation all circuits utilize utility power ONLY
• Backup power sources are not utilized regardless of the quality or condition of utility power
• Overload protection re mains available during bypa ss mode operation
• During initia l setup and configura tion the LCD displays the particula r se tting or value t hat is
to be entered or changed
• During regular operation the LCD is used with various LED indica tors and push buttons
providing UTS status messages, warnings
• During regular operat ion the LCD is used with various LED indicators and push buttons to
perform required actions
Semiautomat ic operation: The UTS automatically switches to generator power once the
generator has been co nnec ted and turned on.
