How to install ONE external braking resistor with internal
thermostat and with fan
WARNING. The resistor should be mounted away from the rest of the
modules or even outside the electrical cabinet, always vertically
and away
from cables and other temperature sensitive material.

Connect one of the two
terminals of the thermostat to
the +24 V DC of an external
power supply in the electrical
cabinet and the other to a PLC
input.
Important. Remember to
manage the chosen PLC input
in the PLC program to generate
an error when exceeding the
limit temperature (160 °C)
detected by the sensor and to
open the contact.
