4.3.3 Wiring
 Precautions
In order to make the functions of AH06XA-5A perfect and ensure the reliability of a system at
the same time, external wiring which prevents noise is necessary. Before installing cables,
users need to follow the precautions below.
(1) To prevent a surge and induction, an AC cable and input/output signal cables which are
connected to AH06XA-5A must be separate cables.
(2) A cable must not be installed near a main circuit, a high-voltage cable, or a cable
connected to a load which is not a PLC. Besides, a cable must not be bound to a main
circuit, a high-voltage cable, or a cable connected to a load which is not a PLC. Otherwise,
effects that noise, induction, and a surge have will increase.
(3) Please connect a shielded cable and a hermetically sealed cable with the ground
separately.
(4) Terminals with insulation sleeves can not be arranged as a terminal block. It is
recommended that the terminals be covered with insulation tubes.
(5) Two-wire connection/Three-wire connection/Four-wire connection:
 Two-wire connection/Three-wire connection (Passive transducer): A transducer and
an analog input module are connected to a power circuit collectively.
 Four-wire connection (Active transducer): A transducer uses an independent power
supply. It is not connected to the power circuit which is connected to an analog input
module.
