When replacing batteries, replace with the same number of the following battery: CyberPower / RB1270X2C for the BL1250U.
CAUTION! Risk of Energy Hazard, 24 V, maximum 9 Ampere-hour battery. Before replacing batteries, remove conductive jewelry such
as chains, wrist watches, and rings. High energy conducted through these materials could cause severe burns.
DO NOT USE THE UPS ON ANY TRANSPORTATION! To reduce the risk of fire or electric shock, do not use the unit on any transportation
such as airplanes or ships. The effect of shock or vibration caused during transit and the damp environment can cause the unit to short out.
CAUTION! Do not dispose of batteries in a fire. The batteries may explode.
CAUTION! Do not open or mutilate batteries. Released material is harmful to the skin and eyes. It may be toxic.
A battery can present a risk of electrical shock and high short circuit current. The following precautions should be observed
when working on batteries:
1) Remove watches rings, or other metal objects.
2) Use tools with insulated handles.

Recharge the UPS for 8-16 hours to fully charge the battery.
1. Ensure that the equipment plugged into the outlet does not exceed the UPS’s rated capacity. If the rated capacity of the unit is exceeded, an
overload condition may occur and cause the UPS to shut down or the circuit breaker to trip.
2. There are many factors that can affect the amount of power that your computer system will require. For optimal system performance keep the
load below 80% of the unit’s rated capacity.
1. Your new UPS may be used immediately upon receipt. However, after receiving a new UPS, to ensure the
battery’s maximum charge capacity, it is recommended that you charge the battery for at least 8 hours.
Your UPS is equipped with an auto-charge feature. When the UPS is plugged into an AC outlet, the
battery will automatically charge whether the UPS is turned on or off.
Note: This UPS is designed with a safety feature to keep the system from being turned on during shipment.
The first time you turn the UPS on, you will need to have it connected to AC power or it will not power up.
2. With the UPS unit turned off and unplugged, connect your computer, monitor, and any other peripherals requiring battery backup into the
battery power supplied outlets. DO NOT plug a laser printer, paper shredder, copier, space heater, vacuum, sump pump or other large

The warranty prohibits the use of extension cords, outlet strips, and surge strips in conjunction with the UPS unit.
4. Press the power switch to turn the unit on.
The Power On indicator lights up and the unit will “beep” twice.
If an overload is detected, an audible alarm will sound and the unit will emit one long beep. To correct this, turn the UPS off and unplug at
least one piece of equipment from the battery power supplied outlets.
Make sure the circuit breaker is depressed and then turn the UPS on.
5. To maintain optimal battery charge, leave the UPS plugged into an AC outlet at all times.
6. To store the UPS for an extended period, cover it and store with the battery fully charged. While in storage, recharge the battery every three
months to ensure battery life.
7. Ensure the wall outlet and UPS are located near the equipment being attached for proper accessibility.
INPUT voltage meter:
This meter measures the AC voltage that the UPS system is receiving from the utility wall outlet. The UPS is designed, through the use of
automatic voltage regulation, to continuously correct output voltage to connected equipment to a safe 110/120 voltage output range. In the
event of a complete power loss, severe brownout, or over-voltage, the UPS relies on its internal battery to supply consistent 110/120
output voltage. The INPUT voltage meter can be used as a diagnostic tool to identify poor-quality input power.
OUTPUT voltage meter:
This meter measures, in real time, the AC voltage that the UPS system is providing to the computer, such as normal line mode, AVR mode,
and battery backup mode. (Note: The OUTPUT voltage meter shows the status of the battery backup outlets.)

Advanced Energy-Saving Patented Bypass Technology
CyberPower’s patented GreenPower UPS™ with Bypass Technology reduces UPS energy costs by up to
75% compared to conventional UPS models. Even when utility power is normal, conventional UPS models
constantly pass power through a transformer. By contrast, under normal conditions the advanced circuitry
of a GreenPower UPS™ bypasses the transformer. As a result, the power efficiency is significantly
increased while decreasing waste heat, using less energy, and reducing energy costs.
When an abnormal power condition occurs, the GreenPower UPS™ automatically runs power through its
transformer to regulate voltage and provide “safe” power. Since utility power is normal over 88% of the time, the GreenPower UPS™
operates primarily in its efficient bypass mode.
What are the Limitations?
The sole and exclusive remedies of the Initial Customer are those provided by this Warranty.
This Warranty does not apply unless the Product and the equipment that was connected to it were connected to properly wired
and grounded outlets (including compliance with electrical and safety codes of the most current electrical code), without the use
of any adapters or other connectors.
The Product must have been plugged directly into the power source and the equipment connected to the Product must be
directly connected to the Product and not “daisy-chained” together in serial fashion with any extension cords, another Product
or device similar to the Product, surge suppressor, or power tap. Any such installation voids the Limited Warranty.
The Product and equipment connected to it must have been used properly in a suitable and proper environment and in
conformance with any license, instruction manual, or warnings provided with the Product and the equipment connected to it.
The Product must have been used at all times within the limitations on the Product’s VA capacity.
The Product was designed to eliminate disrupting and damaging effects of momentary (less than 1ms) voltage spikes or impulses
from lightning or other power transients. If it can be shown that a voltage spike lasting longer than 1ms has occurred, the occurrence
will be deemed outside the rated capabilities of the Product and the Limited Warranty is void. CyberPower Does Not Cover or
Undertake Any Liability in Any Event for Any of the Following:
Loss of or damage to data, records, or software or the restoration of data or records, or the reinstallation of software.
Damage from causes other than AC Power Line Transients, spikes, or surges on properly installed, grounded and
code-compliant 120 volt power lines in the United States and Canada; transients or Ethernet lines, when properly installed and
connected. (This exclusion applies, for example, to fluctuations in data transmission or reception, by CATV or RF transmission
or fluctuations, or by transients in such transmission.)
Damage from any circumstance described as excluded above with respect to the Product.
Damages from fire, flood, wind, rain, rising water, leakage or breakage of plumbing, abuse, misuse or alteration of either the
product or the Connected Equipment.
CyberPower excludes any liability for personal injury under the Limited Warranty and Connected Equipment Guarantee.
