FLEXmax 100
Here is an example of how to wire the Tigo TS4-R-S with an FM100. The key is to give the FM100
the proper signal to disconnect power to the FWPV6-FH600-SDA during a rapid shutdown event. The
FM100 requires a closed circuit signal during normal operation and an open circuit during a rapid
shutdown event. Two different options are:
 Wiring across a dry contact that opens during a rapid shutdown event, and connecting that to the
FM100 RSD input on the C
ONTROL WIRING TERMINAL BLOCK (also called the AUX terminals).
 Connect the 24 Vdc output of the switch to a 24-volt-rated normally open device that will open
upon loss of 24 Vdc and close with the presence of 24 Vdc.
The FWPV6-FH600-SDA should be powered on the controlled side of the switch (third party
NEC compliant), so that upon a rapid shutdown event 24 Vdc will be disconnected from the
FWPV6-FH600-SDA combiner box. The device O
FF position shall indicate that the rapid shutdown
function has been initiated for all PV systems connected to that device. An LED or other indication
may need to be used depending on the switch.
