Notes
■ Before using
Charge the battery soon after purchasing the unit.
▪ If you do not use the unit for a long time after the purchase, the battery may deteriorate and
the battery may become unusable.
▪
Connect this unit to the input power supply and turn ON the “Power” switch to charge the
battery.
When moving the unit fro m a col d p lace to a warm place, leave it for sev eral h our s b ef ore
using it.
▪
If the unit is promptly turned ON after being moved to a warmer place, condensation may
form inside the unit and cause it to fail.
Take measures for handling unforeseen accidents, such as data backup and system
redundancy.
▪ The output may stop when there is failure in this unit.
■ Connecting
Do not short the output lines of the unit to each other, and do not short the output lines
to the ground.
▪
The unit may fail.
In the event you transfer or sell this unit to a third party, please include all of the
documentation that came with the unit. This is to ensure that the unit is used in line with
the conditions described in the included documentation.

Safety precautions
16
■ Using
Before stopping the input power supply to the unit, turn OFF the “Power” switch of the
unit.
▪ The unit enters Battery Mode when input power supply is stopped.
▪
If the frequency of backup operation becomes high, the battery life may be significantly
reduced.
Do not use for an application that frequently requires Battery Mode.
▪ The battery will deteriorate and fail to maintain the specified backup time.
If you want the UPS to stand by in a UPS startup state, set 3 months or less for the input
power supply stop period.
▪ This UPS startup state means either of the following states:
(a) A state of waiting for startup triggered by a remote ON/OFF or BS signal.
(b) A state of waiting for startup when cold start is enabled.
▪
If the UPS is left unused in the above state for 3 months or longer, the battery goes into
overdischarge state, and the backup time may become shorter or the battery may become
unusable.
■ Storing
Storing the battery in UPS for a long term, store at an environment less than 25°C and
recharge 10 to 15 minutes the battery within 1 year.
▪ The battery self-discharges even when it not being used, and it goes into overdischarge
state if it is left for a long period of time. The backup time may become shorter or the battery
may become unusable.
▪ We recommend keeping the temperature 25°C or less when storing the unit for long periods
of time.
▪
Turn OFF the unit’s “Power” switch when storing it.
Do not install or store the unit in a place exposed to direct sunlight.
▪ The rise of temperature may cause the built-in battery to deteriorate rapidly and become
unusable.

▪ Models of this product that comply with EC Directives also conform to the Common Emission
Standard. Radiated emission characteristics (10-m regulations), in particular, may vary depending
on the configuration of the control panel used, other devices connected to the control panel, wiring,
and other conditions. Therefore, even when using a model of this product that complies with EC
Directives, you must confirm and ensure the compliance to EC Directives of the entire machine or
equipment.

▪ The Uninterruptible Power Supply (UPS) protects such devices as PLC and IPC* from power
failures, voltage variations, and instantaneous voltage drops.
▪ Under normal conditions, the UPS outputs DC24V of electrical power from the DC power supply
as-is. When an abnormality is detected in the DC24V power supply such as a power failure and
voltage variation, the UPS switches to battery supply to continue to provide DC24V of electrical
power.
▪ For the specifications of PLC and IPC for power supply input and operation in the event of
momentary power interruptions, check the respective manuals.
