Long Term Storage
If the UPS is to be stored prior to use, it should be stored in a clean, dry environment and away from
temperature extremes. It is recommended that the equipment be stored in a temperature controlled,
moderate humidity environment. Table 1 below provides the temperature and humidity storage limits:
NOTE:
When storing equipment, every 8°C above 25°C reduces the shelf life of the battery by 50%. More
frequent battery charging is required to maintain the batteries in storage at these greater temperatures.
Environmental
Conditions
The UPS must be installed vertically on a level and even surface and in an area protected from extremes
of temperature, water, humidity and the presence of conductive powder or dust (See Table 2 on page 8).
Do not stack units and do not place any objects on top of a unit.
The functional temperature range of the UPS is 32°F to 104°F (0°C to 40°C).
The ideal ambient temperature range is 60°F to 77°F (15 °C to 25°C).
Expected battery runtimes and battery life is based on operational temperatures between 68°F and 77°F (20°C
and 25°C). Operation of the equipment above 77°F (25°C) reduces the service life of the batteries dramatically.
Floor Loading
Taking into consideration the weight of the UPS as shown in Appendix A: Features and Specifications , it is necessary that the floor in the chosen location be capable
of supporting the weight of the unit.
Ventilation and
Accessibility
The area chosen for the UPS must have sufficient space for the installation to be completed. Access doors
must be sufficiently sized to permit clearance of the unit, see “Installation” on page 8
It is necessary to leave a minimum space of at least two inches (50 mm) around the side and rear panels
to allow a flow of air.
Electrical maintenance and servicing, which may involve removal of the panels (see Figure 5) requires
access to all four sides of the UPS. Provide the necessary space or use a flexible wiring system to allow
movement of the UPS.
