Wiring

This section describes how to wire a drive unit and mechanical system inputs to the
QD72P3C3.
The following describes the precautions for wiring the QD72P3C3. Read these
precautions together with "Section 5.1 Handling Precautions" to ensure work safety.
5.4.1

Wiring precautions

(1) Correctly wire cables to the QD72P3C3 after checking the terminal
layout.
(For details of terminal layout, refer to "Section 3.5.2 Signal layout for
external device connector".)
(2) Correctly solder or bond the external device connector (A6CON1/
A6CON2/A6CON4). An incomplete soldering or bonding may cause a
malfunction.
(3) Be careful to prevent foreign matter such as dust or wire chips from
entering the QD72P3C3. Failure to do so may cause a fire, failure or
malfunction.
(4) A protective film is attached to the top of the QD72P3C3 to prevent
foreign matter such as wire chips from entering the module during
wiring. Do not remove the film during wiring. Be sure to remove it for
heat dissipation before system operation.
(5) Securely mount the external device connector (A6CON1/A6CON2/
A6CON4) to the connector on the QD72P3C3 with two screws.
(6) When disconnecting the cable connected to the QD72P3C3 or drive unit,
do not pull it by holding the cable part. Hold the connector connected to
the QD72P3C3 or drive unit and disconnect it. Pulling the cable part with
the cable still connected to the QD72P3C3 or drive unit may cause a
malfunction. Doing so may also cause damage of the QD72P3C3, drive
unit or cable.
(7) Do not bind together or locate close to each other the QD72P3C3 cables
connecting to external I/O signals or drive unit with the main circuit line,
power line, and load lines other than for the programmable controller.
Keep a distance of 100mm (3.94inch) or more between those cables and
lines. Failure to do so may cause a malfunction due to noise, surge, or
induction.
