5. WIRING

5.1 Precautions Against Wiring

As one of the requirements to give full play to A1SJ71PB93D’s functions 
and make up the system with high reliability, it is necessary to have an 
external wiring unsusceptible to an influence of noise.  Precautions 
against external wiring of A1SJ71PB93D is described below.

(1) Do not route the wire of A1SJ71PB93D close to or bundle it 

together with the main circuit and high-tension lines, or the load-
carrying lines from other than the PLC. Otherwise, the module may 
be susceptible to an influence of noise and surge induction. 

(2) The wires from the input/output modules of the PLC should be 

away from the communication cable as far as possible as shown in 
the figure below.

(3) Grounding

(a) When the A1SJ71PB93D is used, the FG and LG terminals of 

the power supply module of the PLC should basically be 
grounded.

(b) If communication cannot be performed after grounding 

because of abnormal voltage applied to the FG terminal, the 
module may be used without grounding.
