Note:
1. Please select braking resistor based on the above table.
Bigger resistor can protect the braking system in fault condition, but oversized resistor may bring a
capacity decrease, lead to over voltage protection.
2. The braking resistor should be mounted in a ventilated metal housing to prevent inadevertent contact
during it works, for the temperature is high.
