How to install ONE external braking resistor with external
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.

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 (200 °C) detected by
the sensor and to open the contact.
Connect the R terminals of the external braking resistor to the X15
connector on the QC-PS-
non-regenerative power supplies.
