SYSTEM CONFIGURATION
The UPS device and the internal batteries make up the system. Depending on the site and load
requirements of the installation, certain additional options are available for the solution.
Planning a UPS system, the following should be taken into consideration:
•
The total demand of the protected system shall dictate the output power rating (VA). Allow a
margin for future expansion or calculation inaccuracies from measured power requirements.
•
Backup time required will indicate the battery size needed. If the load is less than the UPS
nominal power rating, then actual backup time is longer.
•
The following options are available:
o
Connectivity Options –SNMP/WEB card
o
Extended Battery Packs - minimum 1 required
See the Specification section of this manual for additional model information.
