Directions for safe use
Before maintaining devices connected to the UPS, turn off the UPS and
remove the AC Input Plug from the wall outlet (commercial power).
●
Even if you remove the AC Input Plug during the operation of the UPS, the backup function of
the UPS keeps feeding power through the power supply output receptacle of the UPS.
●
In a case where the scheduled operation is ON and the AC Input Plug of the UPS is put in a
wall outlet (commercial power), the UPS starts feeding power at the starting time of the
scheduled operation.
Cautions
(maintenance)
Do not short-circuit the battery with a metal object.
●
Doing so may result in burn injury or fire.
●
Even in a dead battery, there is some current remaining.
Do not toss a battery into a fire. Do not try to break a battery.
●
The battery may explode or dilute sulfuric acid may leak.
Do not use any batteries other than those specified.
●
Doing so may lead to a fire.
●
Battery pack product models: BP150XR (for BN100XR, BN150XR), BP240XR (for BN240XR,
MB240XR)
Do not use a new battery and an old battery at the same time (when adding
BN240XR battery).
●
Rapid deterioration of battery may occur, and dilute sulfuric acid may leak.
Do not drop the battery, and make sure that it does not receive any strong
impact.
●
Dilute sulfuric acid may leak.
Do not replace the battery in a place near flammable gas.
●
A spark may occur when connecting the battery, and lead to a fire.
Replace a battery on a structurally sound base.
●
Hold the battery securely with both hands to avoid dropping.
●
Failure to do so may result in injury due to the battery falling, burns, or injury.
If there is liquid coming from the replaced battery pack, do not touch it.
●
If touched, the liquid (dilute sulfuric acid) may cause burn injury or blindness.
Do not disassemble or modify the battery.
