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.
Terminals 17 to 18 “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.
Terminals 19 to 20 “ROOM TEMP. HIGH” contact input (IN5)
Input fed by a thermocouple that monitors room temperature.
External thermocouple is user supplied.
NOTE : In all cases, a switch having a plate is recommended in order to reduce
possibility of accidental operation.
