Notes
After purchasing the UPS, charge the battery until the battery charge indication shows
that the battery is fully charged.
●
If you do not use your UPS for a long time after purchase, the battery may deteriorate and become unusable.
●
After inserting the AC Input Plug of the UPS into a wall outlet (commercial power), the battery automatically
begins to charge.
Before storing the UPS, charge the battery until the battery charge indication shows
that the battery is fully charged.
●
In a case where you do not use the battery, it discharges naturally and goes into over discharge status
after it is left for a long time. The backup time may become shorter or the battery may become unusable.
●
The maximum possible storage period for the battery installed in the UPS is 6 months (after being fully
charged).
●
If the storage period is to exceed 6 months, recharge the battery before 6 months have passed by con-
necting the AC Input Plug to a wall outlet (commercial power).
●
When storing the UPS, make sure that power switch (
) is turned OFF.
Do not create a short between the output lines of the UPS, or a ground fault between
the output lines and the ground.
●
The UPS may fail.
When the UPS is in operation, do not insert the AC Input Plug into the Power Supply
Output Receptacle of the same UPS.
●
The UPS may fail.
Shut down the UPS before cutting commercial power supply.
If the power switch cannot be turned OFF, perform an auto shutdown of the UPS
using the UPS monitoring software with the minimum required backup time.
●
The UPS goes into Battery mode whenever commercial power is cut. By continuing to run the devices on the
battery and recharging the battery, the life expectancy of the battery is significantly shortened.
The less you repeat charges and discharges, the longer the life expectancy of the battery will become.
Do not connect a page printer to the UPS.
●
The peak current of the page printer is large, so it may be detected as an overcurrent, or the resulting
instantaneous voltage drop may be detected as a power failure.
●
Operation may switch between Line mode and Battery mode, reducing battery life.
If the unit is used with an inductive device such as a coil or motor, check
the operation beforehand.
●
With some types of devices, the effect of inrush current may cause this unit to stop operating properly.
Do not perform a withstand voltage test.
●
The power input circuit has a built-in surge absorber element. A withstand voltage test may break it.
●
When performing an insulation resistance test, conduct it in the 250V DC range.
Recycling and discarding the battery
●
The UPS has a lead acid battery. The battery is a recyclable and valuable resource. We need
your cooperation in recycling old batteries, batteries that you replace with a new batteries, and
the batteries you used to discard.
Installation and storage places
●
Do not install or store the UPS in a place exposed to direct sunlight.
High temperatures may cause the battery to deteriorate and become unusable.
