Precautions Against Wiring
As
one of the requirements to give f u l l play to AJ71 PB92'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 AJ71 PB92 is described below.
(1) Do not route the wire of AJ71 PB92 close to or bundle it together with the
main circuit and high-tension lines, or the load-carrying lines from other
than the programmable controller. Otherwise, the module may be sus-
ceptible to an influence of noise and surge induction.
(2) The wires from the inputloutput modules of the programmable controller
should be away from the communication cable of PROFIBUS-DS inter-
face module as far as possible as shown in the figure below.
