8. 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 operate within the On-line Tolerance range of
-15%
to avoid transferring to Bypass. 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 Bypass can be programmed to accept one of three voltage tolerances without dropping the
load.
4.
The UPS should not be used with a load that has a rated input voltage that is smaller than the
output voltage of the UPS.
5.
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 (oversizing the UPS
for locked rotor current would be required).
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 of the UPS maintain a residual charge for a while after turning the UPS off.
9.
DO NOT attempt to disassemble, modify, or repair the UPS. Repairs and servicing should only be
performed by Toshiba Field Service personnel.
10.
DO NOT remove any covers of the UPS when the power is on.
11.
Turn the power on only after installing ALL of the covers.
12.
If the UPS should emit smoke, produce an unusual odor, or make sound, turn the power off
immediately.
13.
Changing/replacing the UPS Batteries should only be performed by Toshiba field service personnel.
14.
Warning signs should be placed on or near the load as a notification that the load is being powered
by the UPS.
15.
Additional warnings and notifications shall be posted at the equipment installation location as
deemed required by Qualified Personnel.
