RSI Connections
The RSI is equipped with terminal connections for power, input
signals, and output signals.
Power Terminals
o
J1
provides power to the RSI itself. To power the RSI, an isolated
Class 2 DC power supply (24 Vdc ± 3%, up to 1.5 Adc) must be
used. Power supply negative (–) connects to pin 3 (black). Power
supply positive (+) connects to pin 4 (red). This wire must be
protected by an appropriately-sized overcurrent protection device.
o
J2
provides power to all PV combiners. In the illustration below,
pins 3 and 4 (black and red) connect to a junction box which leads
to the
P
WR
port on the FireRaptor combiners.

System Wiring
o
Install the PV modules in series strings using the FireRaptor MLPE devices (OBFRS-01).
Connect these strings to the combiner.
The
S
TR
(string) terminals are used for series string connections. The
P
AN
(panel) terminals are used for PV module connections. The
P
WR
I
N
and
O
UT
terminals
receive and distribute power from the
J2
power supply in the RSI (which is powered by the class 2 power supply). It can power up to 114
OBFRS-01 devices per RSI.
One string is depicted. The FWPV4-FH600 combiner can receive up to 4 strings.
o
Connect the combiner output to the charge controller. To use the integrated FM100 arc fault protection,
this must utilize approved PV circuit breakers such as
those on the GSLC.
o
Connect the RSI J3 terminals to the charge controller’s rapid shutdown terminals. The “daisy chained” terminals may be connected to other charge controllers
or to the inverter’s on/off circuit.
o
Connect the Class 2 power supply to the RSI J1 terminals.

Power Supply
IMPORTANT: J4
If safe status input devices are not installed, a jumper must be installed on
J4
. With no connections,
the
S
OLAR
O
FF
(“safe”) indicator will not light even if the
R
APID
S
HUTDOWN
switch is
O
FF
.
IMPORTANT: J5
The AFCI status signal that triggers the
J5
output is not functional unless this product is used
with the ICS Plus PV combiner.
IMPORTANT: J6
The factory-installed
J6
jumper must remain in place if an external switch is not connected.
Leaving these contacts open will cause a continuous shutdown.
