5. Installation

5.1 System Configuration and Sizing
The internal electronics of the UPS plus the internal battery or batteries constitute the system.
Please make sure that the following factors have been taken into consideration:
1. The total demand of the protected load determines the UPS power (VA) requirements. Allow
some margin or headroom for future expansion or power requirement calculation inaccuracies.
2. Aside from power (VA) requirements, backup time needs to be considered. If the power
consumed by the load is less than the nominal power rating of the UPS, then the actual
backup time will be longer.
3. The following options are available, depending on application and load requirements:
a. . External Battery Packs (EB s) for extended run-times
b. . Input/Output transformer cabine
c. . Maintenance bypass switch
d. . Connectivity and control options (e.g. relay card, SNMP/WEB car
5.2 Environment
Ensure that all environmental requirements are met, otherwise the safety of installation
personnel and users cannot be guaranteed. In addition, the unit may sustain damage or
malfunction.
Please adhere to the following environmental instructions when locating the UPS and EBP's:
1. Avoid temperature and humidity extremes. The optimum operating temperature range is
between 59°F and 77°F (+15°C and +25°C).
2. Provide protection against moisture or avoid altogether if possible.
3. Ensure there is at least 4 inches (100mm) behind and 2 inches (50mm) on each side of the
UPS for ventilation.
4. Ensure that the front of the UPS remains unobstructed for access to the control panel and
LCD display.
5. External Battery Packs must be installed next to or under the UPS.
