generator operation). Power demand is turned ON when the contact is
closed. Power demand is turned OFF when the contact is open.
Terminals 15 to 16
"Asynchronous Command" contact input (IN3)
Used to create an asynchronous condition between the static bypass source
and the inverter. Asynchronous condition is enabled when the switch is
closed. Asynchronous condition is disabled when the switch is opened.

“
BATTERY TEMP. HIGH
”
contact input (IN4)
Input fed by a thermocouple that monitors battery temperature. The
converter float voltage level is reduced for battery over-temperature
conditions. Use battery manufacture recommended thermocouple.
