Both SkyBox and FM100 use continuity to determine when a rapid shutdown event has occurred.
An open circuit signals a rapid shutdown event and disables the PV input to the FM100 or the SkyBox.
(If programmed, it will also disable the backup load output.) A closed circuit signals to the FM100 or
SkyBox that PV should be ON. This logic will be used to integrate third-party rapid shutdown devices.
ICS Plus with a charge controller is an independent system. However, optionally the
two systems can be
integrated through the Rapid Shutdown Initiator (RSI). When the RSI is set to
O
N
or
O
FF
,
J3
can signal
to an external source through an open or closed circuit. If there is an external switch, this can be
connected to
J6
. This automatically gives a rapid shutdown signal to the RSI without turning the red
knob to
O
FF
. The BRK-CTRL-DC cannot be used as the power supply for the third-party devices.
Please read the
FLEXware Integrated Combiner Solution Plus Owner’s Manual
for more information on
the RSI and the limitations on each

port.
Switch-based communication (open/closed digital signals) works best for OutBack products throug
h the
auxiliary ports. We do not recommend third-party options that use power line communication at this time.

RSI Communication to or from a Third-Party Device
When using a third-party power supply for the ICS Plus, be aware that it must be an isolated Class 2 DC
supply, 1.5 Adc maximum, 24 Vdc ± 3% maximum (PWRSPLY-24). Remember to consider the power
consumption of OutBack units when deciding on power supply sizing.

Current draw per unit
ICS Plus Combiner 0.170 Adc
RSI 0.060 Adc
Understanding how the OutBack products rece
ive and give signals
during a rapid shutdown can help
integrate many third-party rapid shutdown devices. For support on third-party devices, please contact
the manufacturer of the device.
