Do not connect a standalone transformer such as a voltage transformer
or isolating transformer to the output side.
●
Overcurrent may damage the UPS.
●
There is no problem in connecting a transformer to the input side.
Do not connect devices that cannot be used with commercial power
supply.
●
When the unit’s power switch is turned ON and an error occurs with the connected device, by-
pass operation is performed and commercial power supply is supplied as is to the connected
devices.
When installing the unit on a rack, place it on the lowest shelf.
●
Injury may result if the unit falls.
Make sure to use the mounting screws included with the brackets.
●
Mounting screws other than those included may not be strong enough to support the unit, caus-
ing it to fall.
●
If you attach the case using long screws other than those included with the product, you may
damage the internal parts of the unit.
Notes
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.
Charge the battery for at least 8 hours soon after purchasing the unit.
●
The battery self-discharges even when it not being used, and it goes into over-discharge state if it is left
for a long period of time.
●
For the BU75RW/BU100RW, the battery can be charged once the AC input plug is connected to a com-
mercial power source. For the BU200RW/BU300RW, the battery can be charged once the plug is con-
nected and the INPUT PROTECTION switch (input overcurrent protection switch) is turned ON.
●
When connecting an additional battery, charge it for at least 24 hours.
When storing the unit, charge the battery for at least 8 hours and turn OFF the
power switch.
●
Even if the unit is not used, the battery gradually discharges, and if it is left for a long time, it goes into an
over discharge state.
The backup time may become shorter or the battery may become unusable.
●
Connect the unit to a commercial power source every 6 months when the storage temperature is 25°C or
less, or every 2 months when the storage temperature is 40°C or less.
●
Turn off the power switch of the unit during storage.
●
Before storing an additional battery, charge it for at least 24 hours.
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.
Do not connect the AC input plug of the unit to its Power Supply Output
Receptacle during the Battery Mode.
●
The unit may fail.
Do not connect a page printer (such as a laser printer) to the unit.
●
The unit repeatedly and frequently switches between Commercial Power Mode and Battery Mode, which
may shorten the life of the battery.
●
The page printer has a large peak current, so an excess of the connection capacity or a power failure due
to instantaneous voltage drop may be detected.
