Connect the terminals of each fan to an outlet of the single-phase 50/60 Hz,
220/240 V AC electrical cabinet. Consumption: 0.15/0.13 A, 23/20 W.
Always install both resistors vertically
Diagram for 2 resistors in parallel with fan and internal thermostat
Connect according to the figure the terminal
labeled +24 V DC to an external 24 V power
supply of the electrical cabinet and the PLC
INPUT 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.
As shown in the figure,
connect the indicated
terminals to the X15
connector of the non-
regenerative QC-PS-

power supplies.
