ONePlus UPS User Instruction Manual 3
Safety
(English)
WARNING: This equipment services power from
more than one source. The output receptacles may
have voltage even when the unit is unplugged.
UPSs present a different safety issue than most
electrical equipment because unplugging the UPS
puts it into backup mode. Unplugging the UPS does
not remove the electrical charge. To ensure that the
UPS is off, turn the power switch OFF before
unplugging the UPS from the wall outlet.
CAUTION: Operating this equipment without
proper grounding may present a risk of electrical
shock.
Do not useAC adaptors with only two conductors to
connect the input line cord to the wall socket as this
will not connect the earth ground to the equipment.
WARNING: Dangerous voltages are present within
this unit! There are no user-serviceable parts inside.
Any repairs or modifications by the user may result
in out-of-warranty repair charges, unsafe electrical
conditions, or violation of electrical code.
Do not remove the cover.All repairs should be done
by qualified service personnel. Voltages inside the
UPS may be lethal. Internal components are
powered even when the UPS is turned OFF. Even
with the battery disconnected and the unit
unplugged, energy is stored in high voltage
capacitors and represents a severe shock hazard.

Theory of Operation
ONePlus UPS User Instruction Manual 7
Theory of
Operation
The ONePlus UPS has two operating modes:
Conditioned AC Power and Conditioned Battery
Backup.
AC Power Mode
When utility AC power is present and within the
correct voltage range, the UPS provides fully
conditioned power:
• Electronic equipment is protected from harmful
transient voltage spikes and other electrical
noise.
• UPS detector circuits continuously monitor the
utility power for blackout, low voltage, and
overvoltage events.
The buck and boost feature will compensate for a
wide range of voltage variations without depleting
the batteries.
Battery Backup
Mode
In an extreme over- or under-voltage situation, the
detector circuits determine that utilityAC power is
no longer in an appropriate voltage range. The UPS
switches to battery to supply continuous conditioned
power.
While in backup mode, detector circuits monitor the
return of utility AC power. The UPS synchronizes
with the utility’s frequency when utilityAC power is
available. The equipment is supplied continuously
with conditioned power even when running in
battery backup mode.

Theory of Operation
8 ONePlus UPS User Instruction Manual
If the battery becomes exhausted while maintaining
the load, battery backup terminates and the UPS
output turns off. A low battery warning is sounded
and transmitted via the communications port
approximately two minutes prior to termination of
battery backup. The UPS monitors the line and
provides output when utility power is restored to
normal operating range.
Fig. 1: ONePlus UPS Front View
Output Overload
Protection
During normal operation, electronic output overload
protection is active. If the output is loaded to more
than 105 percent of the UPS rating, battery power to
the UPS is not available. To reset, turn the UPS OFF,
removesome of theload,then turn theUPSON. (For
GS compliance: The power distribution system for
all models is type TN.)
Input Protector
A grossly overloaded UPS trips the rear panel circuit
breaker. The front panel display reads “c1.” To reset
the circuit breaker, push the button in.
• If the circuit breaker trips repeatedly following
reset,unplug the equipmentfromthe UPS output
receptacles and reset the circuit breaker once
again.
• If operation appears to be normal, check the total
equipment load. Add your equipment to the
output one device at a time. Check the front
panel display after each device is powered ON.

ONePlus UPS User Instruction Manual 9
• If the circuit breaker trips with nothing plugged
into the output receptacles, there may be an
internal problem with the UPS. Call ONEAC
Technical Services for assistance (refer to
page 1).
Setup and
Installation
Before shipment, this product was tested, inspected
and found to be free of mechanical and electrical
defects. Upon receipt of your UPS, carefully
examine the packing containers for any sign of
physical damage. Notify the carrier immediately if
damage is present. After inspecting, carefully
unpack the UPS. Retain the packaging materials for
reuseor disposeofthe materials properly, see Return
Procedure on page 30. Once unpacked, inspect and
test the unit for hidden damage that may have
occurred in transit. If damage is evident, contact
ONEAC Technical Services.
Installation
When selecting a location for your UPS, be sure that
the unit is near a properly wiredAC electrical outlet
and is easily accessible for all other connections (the
loads and/or optional communications cable). Leave
at least 2 inches of clearance on each side of the UPS
for proper ventilation.
CAUTION: Do not cover or install the UPS in a
confined or enclosed space.
Choose an area that is clean and dust-free. If the
environment is dusty, clean the outside of the unit
with a vacuum cleaner.
For optimal battery life, keep the UPS at an ambient
temperature of 25°C (77°F).
LongTerm
Storage
Improper long-term UPS storage may damage the
UPS battery and invalidate the battery warranty.
Unplugging a UPS from itsAC utility power source
for an extended period of time results in lost battery
charge. Restoration of charge to maximum capacity
requires 24 - 48 hours.
Inspection and
Unpacking

Setup and Installation
10 ONePlus UPS User Instruction Manual
To keep the battery enclosure fully charged and to
maximize the life of the battery, plug the UPS into an
outlet while it is in storage. If the UPS is stored
without power access, plug it into a power source for
24 hours at least once every 4 - 6 months.
ATTENTION: If the storage temperature is greater
than 30
° C (86 ° F) plug the UPS into a power source
for 24 hours every 2 to 3 months.
ATTENTION: The UPS should not be stored at
temperatures below -15
° C (+5 ° F).
Ventilation
The ventilation requirement for ONePlus is a
minimum of 2 inches (50 mm) of clearance on all
sides.
Grounding the
Unit
To eliminate shock hazard, connect the unit to a
properly grounded AC receptacle.
Before applying power, verify that the available line
voltage matches the voltage listed on the rear-panel
label.
CAUTION: Interruption of the protective grounding
conductor or disconnection of the protective earth
terminalpresentsa potential shock hazardthat could
result in personal injury and damage to the
