Wiring the RPO Board on the Battery Module Combiner Box

ELECTRIC SHOCK

Even if the battery LED is OFF, the energy storage system may be energized by the power conversion system (inverter-charger / MPPT controller).
Even if the Battery Module Combiner LED is OFF, the combiner box may be energized with power from the power conversion system (inverter-charger / MPPT controller).
Verify the terminal voltage with a voltmeter before handling any components in the energy storage system. Do not touch the energized surfaces of any electrical component in the enclosure.

Failure to follow these instructions may result in death or serious injury.

De-energize the Power Conversion equipment.
Switch the Battery Module Combiner Breaker to the OFF (Open) position.
Switch all Battery Modules to OFF.
Disconnect all the Amphenol SurLok Plus connectors from all the battery modules to isolate the Battery Module Combiner.
Protect the Battery Module terminals from short-circuiting and touch by covering them with terminal covers or electrically rated tape.
Disconnect the Power Conversion cables attached to the Battery Module Combiner.
Plan:
1. Where to locate the E-stop or bladed lockable disconnect. Typically, the emergency switch is located close to the meter.
2. Where to route the wires.
Access the top of the Battery Module Combiner and remove the top cover.
The RPO board is at the front of the Battery Module Combiner, where the RJ45 ports are.

Touch a grounded metal surface to remove the static electricity from your body.
Remove the screws securing the RPO board, then gently hold the top and bottom of the RPO board and dislodge it.
Once removed, you can access the wiring terminals of the RPO board.
Connect an E-stop button or a bladed lockable disconnect to the RPO board.
