Option 15 – Power-On Inverter Test (POIT)
When this option is set to the factory default ON setting, the Esprit will perform a short
battery/inverter test shortly after it is turned on. This test is only performed only if the UPS is
able to power up the load from utility power first. If the POIT is enabled, the UPS will power up
the load from utility power, then briefly switch to battery power approximately
5-7 seconds after it is powered up. The UPS runs on battery for only 3-5 seconds, so no
significant drain on the battery will occur.
The POIT is disabled if this option is turned OFF. The setting of this option has no effect on the
scheduling and execution of the monthly inverter/battery test, which runs less
frequently than the POIT but is considerably more exhaustive.
