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 rang e of +10% t o -30% of
the rated input voltage. The input freque ncy 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 sta rting c urrent 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 b e for e op e ning the d oo r
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.
