We recommend reading through this guide in its entirety at least once to fully understand all of the features of your Power Distribution Hub.
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.
RS485 Ports are not currently used in FRC and are included for potential future use
Always make sure the the Power Distribution Hub is disconnected from any power source before adding or modifying connections.
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.
Smart Tug - tugging on a wire to test the connection with a reasonable amount of force.
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.
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.
Over time circuit breaker holders will become easier to use and stay snug!
When removing a circuit breaker, make sure to rock the circuit breaker back and forth to make it easier to pull up on.
