Connecting braking resistor BW..-P / BW..-T / BW.. to X3 / X2
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.
Overload protection for braking resistors BW:
WARNING
The surfaces of the braking resistors get very hot when the braking resistors are loaded
with P
N
.
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.
