Operating Precautions

1) The UPS should not be powered up until the entire User's Manual has been reviewed, and
understood.
2) The input power source voltage must be within +10% to -15% of the rated input voltage to
initially start the UPS. The input frequency must be within the rated input frequency range.
Voltages and frequencies outside of the permissible range may cause internal protection
devices to activate.
3) Ensure the three-phase input is connected in clockwise rotation (CW). The UPS internal
circuitry is designed to disable further operation if the input phasing is installed in counter-
clockwise rotation (CCW).
4) The UPS should not be used with a load whose rated input is greater than the rated UPS
output.
5) Do not use the UPS to provide power to motors that require high starting current or a long
starting time such as vacuum cleaners and machine tools.
6) Do not insert metal objects or combustible materials in the unit's ventilation slots.
7) Do not place, hang, or paste any objects on the top or on the exterior surfaces of the UPS.
8) The capacitors of the UPS maintain a residual charge for a while after turning off the UPS.
The required discharge time for each UPS is provided via a cabinet label. Wait for at least
the minimum time indicated on the label and ensure that the front panel LED's have gone
out before removing the front panel of the UPS after the UPS power has been turned off.
9) Do not attempt to disassemble, modify, or repair the UPS. Call TOSHIBA Service for repair
information.
10) Turn the power on only after attaching ALL the covers and 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 into contact with these items.
13) Warning signs should be placed on or near the load to let people know 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.
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.

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
