TOSHIBA
3.0 Precautions
3.1 Installation Precautions
1) Install the unit in a well ventilated location; allow at least 10 cm (4 inches) on
all sides for air ventilation and for maintenance.
2) Install the unit in a stable, level, and upright position which is free of vibration.
3) Install the unit where the ambient temperature is within the correct operating
range (see Specifications Section 5.1).
4) Do not install the UPS in areas that are subject to high humidity.
5) Do not allow direct sunlight to shine on the unit.
6) Do not install the UPS in areas which are subject to contamination such as
high levels of airborne dust, metal particles, or inflammable gas.
7) Avoid installation near sources of electrical noise and
always make sure that the unit ground is intact to
prevent electrical shock and to help reduce electrical noise.
8) Do not install where water or any foreign object may penetrate the UPS.
9) This UPS generates and can radiate radio-frequency energy during operation.
Although RFI noise filters are installed inside the unit, there is no guarantee
that the UPS will not influence some sensitive devices which are operating
close by. If such interference is experienced, the UPS should be installed farther
away from the effected equipment and/or powered from a different source than
that of the affected equipment.
10) User should provide output overcurrent protection for hardwired UPS versions.
See Safety Instructions on page vi for the correct device rating.
3.2 Prestart Precautions
1) Before connecting the UPS to a power source; move the MCCB switch
(ON/OFF), on the rear panel (See Section 9.1), to the OFF position and move
the operation switch (RUN/STOP), on the front panel (See Section 9.1), to the
STOP position.
2) Before starting the UPS unit, on dual voltage units, one of the two jumper-
selection options available for UPS terminals 11 through 13 (see Section 9.1 for
location) must be used to select correct input voltage (see Section 4.0 for
connection details).
3.3 Operating Precautions
1) The UPS should not be powered up until the entire operation manual has
been reviewed.
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 tolerance range may cause
internal protection devices to activate.
