SD Card

The microSD card is used to update the FLEXmax 100 firmware. See page 53.

Fan Connector

This is the connection for the FLEXmax 100 cooling fan.

Accessory Terminal Block

This block of terminals has connections for the A

output, for the Battery Sense function, and for the

Rapid Shutdown function. The terminals accept wire from #16 AWG to #24 AWG.

Press on the indented area A with a narrow tool to unlock each opening while inserting the wire in B.

The wire should be inserted at approximately a 45° angle (perpendicular to the opening).

Rapid Shutdown Terminals

Terminals 1, 2, 3, and 4 are used for the Rapid Shutdown function. In an emergency, a responder may

need to quickly place the PV system in a de-energized state. These terminals can receive Rapid

Shutdown commands to quickly shut down the FLEXmax 100. Multiple controllers can be connected in

parallel on a single Rapid Shutdown circuit. See page 24 for more discussion of the Rapid Shutdown

function, including hookup diagrams.

IMPORTANT:



A jumper, J5 is factory-installed on pins 1 and 3. It may need to be removed if another

device is installed.



The FLEXmax 100 will not function unless jumper J5, the OutBack RSI, or a similar

normally-closed device is installed. Initial power-up will result in a Rapid Shutdown

signal. (See page 55.)

If an OutBack system display is present, the Rapid Shutdown function will deliver a Fault Input Active

error message (see page 38).
