Notes:
*1 Wiring length shown above is the total wiring length from Infilex AC to a device in connection, including the wiring to and from an external
terminal block.
*2 Power supply and ground wires are connected to the M3 screw terminals. Crimp the terminal lugs on the wire ends.
*3 Communication and input/output wires are connected to the screwless push-in terminals. Strip the wire sheath and connect the wires.
Sheath strip length: 8 mm (Pin terminal cannot be used.)
*4 RTD (Pt1000) temperature input is two-wire. Take the measuring error into account because the wire resistance causes measuring error.
For instance, 1.25 mm
2
size wire causes approx. 0.1 °C measuring error every 10 m. Correct the measuring error by setting Infilex AC.
*5 When the valve/damper is connected for the system common wiring, the valve/damper operating current flows through the common line.
Hence, the specification is as shown above. For a 20 m long IV 1.25 mm
2
cable, 4-wire connection is necessary to prevent the operating
current from flowing through the common line.
