3. The input frequency must be within the rated input frequency range.
4. The UPS should not be used with a load that has a rated input that is greater than the
rated output of the UPS.
5. If using the UPS to provide power to motors that require high starting current or with
motors that require a long starting time, call Toshiba support for guidance in oversizing
the UPS for locked rotor current.
6. DO NOT insert metal objects or combustible materials in the ventilation slots of the
UPS.
7. DO NOT place, hang, or paste any objects on the exterior surfaces of the UPS.
8. The capacitors in the UPS maintain a residual charge for a while after turning the UPS
off. Wait five (5) minutes before opening cabinet. This allows the system capacitors
to fully discharge.

representative for repair information.

11. DO NOT open any UPS bay access doors when power is on.

being powered by the UPS.

location as deemed required by Qualified Personnel.
While operating in the inverter mode, placing the input breaker in the "OFF"
position will switch the UPS to the DC supply 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
internal circuits have been fully discharged.
The UPS could be damaged if the unit is not fully discharged before the breaker is
reset.
