Before You Start

Install the REV Hardware Client before continuing with this guide. The REV Hardware Client is the best way to verify that the Power Distribution Hub is configured correctly and is required for using the CAN Interface.

Power Distribution Hub Wiring Diagram

Latching WAGO Terminals: Battery Input and High-Current Channels

• For Battery Input use 18 to 4 AWG Wire, Stripped back ~0.75” (20mm)

• For High-Current Channels use 24 to 8 AWG Wire, Stripped back ~0.5” (12mm)

• Flip open the lever with an upward motion.

  • You can open the lever all the way to have it stay open or you can open it half way for quick wire changes.

• Insert stripped wire into connector opening.

• Push down the lever.

• Test the wire by giving it a smart tug to ensure wire is connected securely.

• Visually inspect to make sure no stray wires are outside of the connector port.

Push-Button WAGO Terminals: CAN and Low-Current Channels

• Use 24 to 18 AWG Wire, Stripped back ~0.35” (8mm)

• Press and hold down connector button.

• Insert stripped wire into connector opening.

• Release connector button.

• Test the wire by giving it a smart tug to ensure wire is connected securely.

• Visually inspect to make sure no stray wires are outside of the connector port.

Circuit Breakers

• Carefully insert the Circuit Breaker (CB) directly into the circuit breaker holder. Ensure that the blades of the circuit breaker slide into the circuit breaker holder.

• Circuit breakers should not be loose or move at all when inserted correctly.

  • If the circuit breaker is loose, remove the circuit breaker and make sure you can see the opening on the circuit breaker holder, then reinsert into the holder.

• New circuit breaker holders fit circuit breakers tightly. This can make it hard to pull out the circuit breaker.

• When removing a circuit breaker, make sure to rock the circuit breaker back and forth to make it easier to pull up on.
