(Tightening torque: 0.22 Nm to 0.25 Nm (2.3 kgfcm to 2.5 kgfcm)
Notes for wiring
• When removing the wire’s insulation, be careful not to scratch the core wire.
• Do not twist the wires to connect them.
• Do not solder the wires to connect them. The solder may break due to vibration.
• After wiring, make sure stress is not applied to the wire.
• In the terminal block socket construction, if the wire is fastened upon counter-clockwise rotation of the
screw, the connection is faulty. Disconnect the wire, check the terminal hole, and then re-connect the
wire.
• If two wires are connected to the plus terminal and minus terminal of the RS485 of AFPG806 (COM4),
use the wires of the same cross-sectional area which is 0.5 to 0.75 mm
