Operating Precautions

1) The UPS should not be powered up until the entire Operation Manual has been read.
2) The input power source voltage must be within +10% to -30% of the rated input voltage.
The input frequency must be within the rated input frequency range. Voltages and
frequencies outside of the permissible range may activate the internal protection device.
3) The UPS should not be used with a load that has a rated input greater than the rated
UPS output.
4) Do not use the UPS to provide power to motors that require high starting current or a
long starting time such as vacuum cleaners or machine tools (over sizing for locked rotor
current required).
5) Do not insert metal objects or combustible materials in the ventilation slots of the UPS.
6) Do not place, hang, or paste any objects on the top or on the exterior surfaces of the
UPS.
7) The capacitors of the UPS maintain a residual charge for a while after turning off the
UPS. The required discharge time for each UPS typeform is provided via a cabinet label
and a CHARGE LED. Wait for at least the minimum time indicated on the label and
ensure that the CHARGE LED has gone out before removing the front panel of the UPS
once the UPS power has been turned off.
8) Do not attempt to disassemble, modify, or repair the UPS. Call your Toshiba sales
representative for repair information.
9) Turn the power on only after attaching ALL the covers and DO NOT remove any covers
of the UPS when the power is on.
10) If the UPS should emit smoke or an unusual odor or sound, turn the power off
immediately.
11) The heat sink and other components may become extremely hot to the touch. Allow the
unit to cool before coming into contact with these items.
12) Warning signs should be placed on or near the load to let people know that the load is
being powered by the UPS.
13) Additional warnings and notifications shall be posted at the equipment installation
location as deemed required by Qualified Personnel.
CAUTION
UPS will continue to provide power to the load. The unit must be in Bypass mode and then
the breaker turned to the OFF position for the UPS to shut down power to the load.
CAUTION
T O S H I B A
When the UPS is in the Inverter mode, turning the breaker to the OFF
position will cause the unit to go into the battery backup mode. The
Do not EPO (Emergency Power OFF) the UPS and then reset the
breaker until the UPS has been fully discharged. The UPS could be
damaged if the unit is not fully powered down before the breaker is
reset.
