External braking resistor
connection terminals

With the application of successive
braking the inverter braking resistor may
overheat. Please replace the built-in
braking resistor with a resistor of larger
watt rating externally.
Replacement Procedures: *2
* Detach the built in resistor from P/R
terminal and insulate exposed ends.
*Install external resistor with larger
capacity (watt)
* The standard resistance of inverter
braking resistor is shown in tables 4.2.b,
4.2c, and 4.2d
Used to connect
the optional
external Dynamic
Brake Package.

NOTE:
Connect AC line power to terminals L1 and L2 in single phase application.
*1.
Single phase input only appropriate for CC 204-222 models.
*2.
The braking resistor of smaller CC series is soldered on the PC Board and can not be
replaced. Consult Drivecon for replacement.
*3.
There is no built-in brake unit in CC models of 15HP and larger. An external brake
unit; VFDB and resistor must be added for 100% brake torque.
*4.
Terminations to inverter must be made with either listed field wiring lug kits or listed
crimp type ring terminals.
