Item

Description

1

Connect an RJ45 network cable between the RJ45 screw terminal adapter connector and the RJ45 receptacle of the LYNK port on the Discover lithium battery.

In a multi-battery configuration, connect the network cable to the last battery in the LYNK network.

2

Connect 14-18 AWG wires to pins 3 and 6 of the screw terminal.

3

Connect the wires from the screw terminal to opposite ends of the Normally Open emergency switch (E-stop button or bladed lockable disconnect).

NOTE: There is no positive or negative for the wires from the RJ45 screw terminal adapter. Connect the wires to opposite ends of the emergency switch.

NOTE

  • The E-Stop switch requires one of the LYNK ports.

    • For AES RACKMOUNT, use the other LYNK port to connect to the LYNK network or LYNK II Gateway.

    • For HELIOS ESS, use the other LYNK port (COM3/COM4) to either connect to the LYNK network or connect the termination resistor. Use the CAN port (COM2) to communicate with the inverter.

  • When using this emergency switch with multiple batteries, apply this connection method to the last battery on the LYNK network.

  • To configure the emergency switch for up to 36 batteries, connect them to the same LYNK network.

Operation

RUN: Enable the emergency switch (close the circuit) by turning the handle of the bladed lockable disconnect to ON or resetting the E-stop button, then turn ON the batteries in the BESS. The E-stop is now in a ready state.

SHUT DOWN: Push the E-stop button or crank the handle of the bladed lockable disconnect to OFF to open the circuit and turn all batteries connected to the battery's LYNK network OFF.
