Introduction
Features of the Product
Thank you for purchasing OMRON's "Uninterruptible Power Supply (UPS)".
●The Uninterruptible Power Supply (UPS) is a device that protects such equipment as a computer
from power outages, voltage fluctuations, instantaneous voltage drops, and voltages surges
caused by lightening and so on (phenomena in which an extremely high voltage is generated
suddenly).
●In normal operation, the UPS directly outputs commercial power input. When the input voltage
becomes low or high, the UPS converts commercial power to a direct current, and then re-
converts it to an AC voltage of stable sine waveform to output power. The UPS adopts the line-
interactive power supply system (on-line type power supply system), which continues sine-wave
output by switching to the power supply from the battery when an error in commercial power such
as a power outage and voltage fluctuation is detected. The UPS is especially suitable for use in a
place where the power supply environment is bad such as where the voltage fluctuates greatly.
●The output capacity of each model is as follows.
BL50T: 500VA/450W
BL75T: 750VA/680W
BL100T: 1000VA/900W

Cautions (for tranportation)
Do not drop or give any strong impact when transport it.
●Overheating, smoke, explosion, or fire may occur in the battery.
Important notice
■Before starting using the product
After purchasing the UPS, charge the battery (for 8 hours or more) at
your earliest.
●If not used for a long time after being purchased, the UPS may become unusable
because the characteristics of its battery become inferior.
●Insert the "AC input" plug of the UPS into the outlet (commercial power supply) to
charge the battery.
Wait for several hours before start using the UPS when it has been
moved from a cold place to a warm place.
●If the UPS is suddenly moved to a warm place, water may adhere to it
(condensation). In such a case, if power is supplied without checking the
condition, the UPS may fail.
Prepare for an unexpected circumstance, such as the data protection
and system redundancy.
●The Uninterruptible Power Supply (UPS) may stop its output due to failure.
■ For Connection
Do not connect a device with large maximum power consumption such
as a laser printer to the UPS.
●Since a printer such as a laser printer has a large peak current, connected-
capacity overload may be detected when the peak current is reached.
Do not use the UPS for an induction device such as an induction coil,
motor, and transformer.
●Depending on the device type, the UPS does not operate correctly due to the
influence of an inrush current and so on.
Make sure of checking the operation first before using the UPS in
combination with the devices with large fluctuations in power frequency,
such as a household power generator.
●When input power is supplied, the UPS automatically recognizes the input power
frequency. Connecting the UPS in a state where the input power frequency is out
of the specified value can cause the misrecognition of the power frequency,
which may result in the abnormal operation. It is okay for the power to switch
from the commercial power supply to the generator's power while the UPS is
running. However, adjust the frequency of the generator to match with the
commercial power supply.
Prevent the short circuit between the output lines of the UPS, or the
output line on the earth (grounding.)
●The UPS may fail.
