For the lowest EMC, it is recommended to use a 2 stage filter like TE Connectivity 30EMC6.

Shunt Braking Resistor Connection
A shunt braking resistor can be activated from Everest XCR by using an external transistor. Any of the 4 general-
purpose outputs can be configured to turn-on when the dc bus exceeds a certain threshold:
The digital outputs provide a 0 ~ 5 V output with a 470
Ω
in series resistance inside the drive. This will typically be
enough to turn on - off a power MOSFET transistor that can withstand at least 30 A braking current, like
IRLR3110ZTRPBF. Ensure that a transient voltage Zener like MM3Z6V2T1G is placed in parallel with the gate of the
transistor and a pull-down 10 k
Ω
resistor ensures a safe off state of the transistor in case of disconnection. If the
shunt braking resistor or circuit is inductive a re-circulation diode like V8P10-M3/86A is needed.
