6. Operating Precautions
1) The UPS should not be powered up until the entire operation manual has been read.
2) The voltage of the input power source must be within the range of +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 devices.
3) The UPS should not be used with a load that has a rated input that is greater than the rated output of the UPS.
4) Do not use the UPS to provide power to motors that require high starting current or with motors that require a
long starting time, such as vacuum cleaners and machine tools (over sizing the UPS for lock rotor current
would be 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 exterior surfaces of the UPS.
7) The capacitors of the UPS maintain a residual charge for a while after turning the UPS off. 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 opening the
door 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 of the covers.
10) Do Not remove any covers of the UPS when the power is on.
11) If the UPS should emit smoke or an unusual odor or sound, turn the power off immediately.
12) The heat sink and other components may become extremely hot to the touch. Allow the unit to cool before
coming in contact with these items.
13) Warning signs should be placed on or near the load as a notification that the load is being powered by the
UPS.
14) Additional warnings and notifications shall be posted at the equipment installation location as deemed required
by Qualified Personnel.
While operating in the inverter mode, placing the breaker in the OFF position will
switch the UPS to the battery backup mode. The output of the UPS will continue
uninterrupted to the load. The unit must be in the bypass mode at the time that the
breaker is placed in the OFF position for the UPS to shutdown power to the load.
After an Emergency Power Off (EPO), do not reset the breaker until the UPS has
been fully discharged. The UPS could be damaged if the unit is not fully discharged
before the breaker is reset.
