Diagnostic Tests
When the UPS is started, a diagnostic test is automatically executed, checking the electronics and batteries, report-
ing any problems on the LCD display.
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
Dry contact card
o Extended Battery Packs
