Connecting braking resistor BW..-P / BW..-T / BW.. to X3 / X2
WARNING
The surfaces of the braking resistors get very hot when the braking resistors are loaded with PN.
Risk of burns and fire.
- Choose a suitable installation location. Braking resistors are usually mounted on top of the control cabinet.
- Do not touch the braking resistors.
Set a terminal to "/Controller inhibit". K11 must be opened and "/Controller inhibit" must receive a "0" signal in the following cases:
- BW..-P: The auxiliary contact trips
- BW..-T: The internal temperature switch trips
- BW..: The external bimetallic relay F16 trips
The resistor circuit must not be interrupted.
