Search Mode Operation in Multiple Unit Configuration
Search mode is automatically enabled in multiple unit installations with two
paralleled Conext SW units. Only the master Conext SW operates, and the slave
unit comes online only when the load exceeds approximately 60% of the rated
output of the master unit. When the load drops below 20% of the master’s rated
output, the slave unit turns off.
For more information on when to set up the Search mode, refer to the Conext SW
Inverter/Charger Owner’s Guide (document part number: 975-0636-01-01) under
Chapter 4 -> Configuring Advanced Settings -> Using Search Mode.
Wiring Schematic
NOTE: Please refer to “Multiple Unit Configuration” on page 1–29 that shows the
wiring schematic employed between two Conext SW inverter/chargers.
IMPORTANT: Follow the same guidelines in “Inverter/Charger Installation” on
page 1–17 when choosing cables and/or wires for AC and DC connections.
WARNING
FIRE, ELECTRICAL SHOCK, AND EXPLOSION HAZARD
Make sure all wiring being used to make multiple unit configurations between
inverter/chargers is disconnected (physically or by opening and locking out
the breaker) from all electrical sources before handling. All wiring must be
done in accordance with local and national electrical wiring codes.
Failure to follow these instructions will result in death or serious injury.
