Fig. 10-4: Circuit diagram for direct connection to a PLC
• Connection to terminal “GND” is imperative for direct connection
to a PLC (Fig. 10-4)!
• For 24 V DC, the mains supply (plug connection A) MUST NOT be used!
• The used 24 V power supply must be sufficiently dimensioned for
the operation of perma ECOSY acc. to its power consumption
(chapter 3.1.2.).
CAUTION
