Site Preparation
the fresh air volume of the battery installation environment must meet the provisions set out in the
EN50272-2001 standards.
Environmental conditions have a significant impact battery capacity and life. The normal operating temperature
of the battery is 20° C, if the ambient temperature exceeds 20° C, battery life will be reduced, whereas, if the
temperature is lower than 20° C, then battery capacity will be reduced. The acceptable ambient temperature
range under normal operating conditions is between 15° C and 25° C. The ambient temperature of the battery
should be kept constant. Avoid positioning the batteries close to heat sources or air ventilation outlets.
Batteries may be installed in the special battery cabinet, which is designed to be positioned close to the UPS.
However, if the batteries are placed on the raised floor, a sustaining bracket must be constructed and installed
under the supporting floor (the same procedure applies to the UPS). In the case of rack-mounted batteries, or
other installation solutions where the battery is positioned at a distance from the UPS, the battery circuit breaker
shall be installed near the battery. In such situations, the connecting cables must be designed to be as short as
possible.
2.1.3
Storage
In the event that the UPS is not to be installed immediately following delivery, is must be stored, in the original
packaging, in an environment where it is protected from excessive humidity and heat sources (see table in Table
2.1 on the previous page for the storage data).
The storage location must be dry and cool, well ventilated, clean and as dust-free as possible.
Note
During the storage, the battery must be charged periodically according to the battery manufacturer's
instructions.
2.1.4
Clearance
The UPS is not fitted with lateral ventilation grills; therefore, no specific clearance is required on either side.
However, since it may be necessary tighten the UPS power terminals at regular intervals, a clearance of 1200 mm
should be guaranteed at the front in order to enable free passage of personnel with the door fully open. Maintain
a minimum clearance of 500 mm at the rear of the unit to permit the air fed out of the UPS to circulate freely.
Figure 2-1 shows the recommended clearance distances at the front and back of the UPS (Top View):
