Take the connection terminals of each fan
to an outlet of the electrical cabinet, sin-
gle phase 50/60 Hz, 220/240 V AC. Con-
sumption: 0.15/0.13 A, 23/20 W.
Always install both resistors vertically
Diagram for two resistors in parallel with fan and internal thermostat
Take the terminal labeled + 24 V DC to an external 24
V DC power supply of the electrical cabinet and the
other one labeled PLC INPUT to a PLC input. Impor-
tant. 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.
Take the indicated terminals to the Re and
L+ terminals of the terminal strip of the
Ballast of the power supply (only PS-65A
or XPS-65).
