Prestart Precautions
1) Before connecting the UPS to a power source move all the breakers (MCCB1, 2,
3, and 4), on the front panel, to the OFF position and move the operation
STOP/RUN, on the front panel (See Section 9 for location), to the STOP position.
3.4
Operating Precautions
1) The UPS should not be powered up until the entire operation manual has been
reviewed and understood.
2) The input power source voltage must be within +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 cause internal
protection devices to activate.
3) The UPS should not be used with a load whose rated input is greater than the
rated UPS output.
4) 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.
5) Do not insert metal objects or combustible materials in the unit's ventilation slots.
6) Do not place, hang, or paste any objects on the top or on the exterior surfaces of
the UPS.
7)
TOSHIBA
CAUTION
Always use caution when connecting or disconnecting load equipment.
The UPS may be supplying power to the output load receptacles
through the bypass circuit. This can occur when the RUN/STOP
switch is in the STOP position, the output breakers are on (MCCB2-4),
and the unit is connected to a source of supply power (See Circuit-
bypass Mode Section 5.1.3).
