Battery and Test Time Configuration:
The test time and battery configuration jumpers are located on the trace side of the
control circuit board located in the inverter module. The jumpers are factory-adjusted
for a test time of approximately 5 minutes. Re-adjustment of test time in the field is
neither recommended nor necessary since shorter or longer times may not sufficiently
test battery reserve or may use an excessive amount of reserve if a commercial AC line
failure occurs during the test cycle.
Battery configuration jumpers have been factory adjusted for 3, 4, 6 or 8-battery
installations per customer order. Resetting the pin jumpers for battery configuration is
neither recommended nor should it ever be necessary to do so.
Analog Adjustments:
Several miniature potentiometers are located on the printed wiring board of the inverter
module. These potentiometers have been factory adjusted for proper charger output
voltage and for correct detection and measurement thresholds. Field adjustment of any
potentiometer in the inverter module should not be attempted; otherwise, degraded power
system performance or damage to the inverter module or batteries may result. If any
potentiometer adjustments are suspected as a cause of operational trouble or erroneous
