3.0 Precautions
Based on the 4200 Series UPS unit's external dimensions and the way the outer panels are
removed; minimum amounts of unobstructed space around the unit is necessary for ventilation
and maintenance access. Figure 3.1 shows the minimum clearances required for proper UPS
site installation.
3.1
Installation Precautions
1) Do not install the UPS on an inclined surface,
or areas that are subject to frequent vibrations
or jolting. This could damage UPS circuits.
2) Do not allow liquids or foreign objects to get
inside the UPS.
3) Allow at least 700 mm (28 in) on the front side
and 500 mm (20 in) on the rear and sides of
the UPS unit for air ventilation and
maintenance access.
4) Do not install the UPS in a location that is
subject to high humidity. Also, do not install
the unit in areas that are exposed to direct
sunlight, or contaminated areas subject to
high levels of airborne dust, metal particles, or
flammable gasses.
5) Verify the ventilation and air conditioning
system at the site is capable of removing the
heat generated by the UPS unit (see Section,
5.1 Specifications, "Environment").
Ambient temperature range for operating the UPS
is 0° to 40°C (32° ~ 104°F);
25°C (77°F) is the
recommended operating temperature for
maximum battery life.
6) Avoid installation near sources of electrical
noise. Always make sure that the unit's
ground is intact to prevent
electrical shock
and help prevent electrical noise.
7) This UPS generates and radiates 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 in near proximity. If such
interference occurs, the UPS should either be
installed farther away from the affected
equipment and/or powered from a different
source than the affected equipment.
