SMARTZONE UPS USER MANUAL
12
seconds. The frequency of the test is user selectable. For the 5-20kVA UPS units, the
battery test may be automated through the network card or scheduled through the
Maintenance Menu on the UPS Display.
Note:
If automatic battery testing is setup through the Network Card, then automatic battery
testing should be disabled through the Maintenance Menu on the UPS Display. If automatic
battery testing is setup through the Maintenance Menu on the UPS Display, then automatic
battery testing should be disabled in the Network Card.
When the battery test runs, the battery discharges for 10 seconds through both the
externally connected load and internal load.
Note:
If a battery test is run just after the UPS was running in the battery state, it may produce a
Battery low (EOD) alarm and/or a Battery Self-Test error because the battery was too low when
the test was started. This does not mean your battery is defective or at end of life. Try rerunning
the battery test after the battery has been fully charged. If Battery low (EOD) alarm is already
present when the battery test is initiated, the UPS will not start the battery test.
System Configuration Modes
Only the 10-20kVA 3-phase UPS units allow the user to change the system
configuration. The system configuration allows the UPS to be connected into a larger
system. By default, all UPS units are configured to be their own independent system.
Single Mode
By default, all UPS units are configured and wired as a single mode system. A single
mode system is a single UPS (and EBP unit(s)) connected to an AC power source, and
that UPS provides the AC power to the load(s).
Parallel Mode
All 10-20kVA 3-phase UPS units may optionally be configured and wired as a Parallel
mode system. A Parallel mode system allows two to four UPS units of the same rating
to be connected in parallel. The Parallel mode system allows the group of UPS units to
behave as one large UPS system and/or as a system with redundancy. (Redundant
units are not calculated in the overall capacity of the parallel system).
Note:
There are critical restrictions for connecting these units in parallel.
