Precautions for Safe Use
Before using
• The battery has not been charged at the time of purchase. Be sure
to charge it before use.
• Connect this unit to the input power supply to charge the battery
unit.
When moving the unit from a cold place to a warm place, leave it for
several hours before 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 unit output lines together, and do not short the battery
connection cable (to 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.
Using
Before stopping the commercial power to the unit, turn OFF the
"Power" switch of the unit.
The unit will stop after 30 seconds of setting the mode selection/
backup operation time selection switch to "0.5".
• 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 unit 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.
• The UPS startup state means the state of waiting for startup
triggered by a remote ON/OFF or BS signal.
• 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 and recharge 15 to 30 minutes the battery within 1
°C
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
storing the unit for long periods of time.
• Turn OFF the unit's power when storing it.
Do not install or store the unit in a place exposed to direct sunlight.
• The rise of temperature may cause the battery unit to deteriorate
rapidly and become unusable.

Correct Installation Method
• For installation, to improve the long time reliability of the UPS, pay
much attention to heat dissipation. Ensure convection of air around
the UPS main body, and use the UPS in an operating condition
below the derating curve.
• During machining work for mounting, make sure that no metal
scrap goes into the product.
• The heat dissipation of the UPS may become worse depending on
how the UPS is mounted; in rare cases, internal components may
deteriorate and get damaged. Use the UPS in an operating
condition based on the derating curve for each mounting direction.
Standard mounting
Note: 1. This UPS can be mounted with the sides in close contact.
Face-up mounting
or less when
°C
Leave 50 mm of space between the upper and lower.
Leave 50 mm of space between the upper and lower.
Up to 3 units can be mounted in close contact.
Follow the derating curve during mounting with the sides in
close contact.
2. When you install devices other than the UPS on the left or
the right of the UPS, leave a space of at least 15 mm.
