How to install ONE external braking resistor with internal
thermostat and with no fan
WARNING. On top of the ER+TH modules, the air temperature can reach
values over 120°C/248°F. Therefore, 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.

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.
