[WIRING PRECAUTION]
Completely turn off the externally supplied power used in the system before installing or placing
wiring.
Not doing so may cause electric shock or damage to the product.
Check the layout of the terminals and then properly route the wires to the module.
Solder connectors for external input signal cable and SSCNET cable properly.
Insufficient soldering may cause malfunction.
Be careful not to let foreign matter such as sawdust or wire chips get inside the module.
These may cause fires, failure or malfunction.
The top surface of the module is covered with protective film to prevent foreign objects such as
cable offcuts from entering the module when wiring.
Do not remove this film until the wiring is complete.
Before operating the system, be sure to remove the film to provide adequate ventilation.
Securely connect the connector for the SSCNET cable to the bottom connector on the module.
When removing the cable or power supply cable from the module, do not pull the cable. When
removing the cable with a connector, hold the connector on the side that is connected to the
module.
Pulling the cable that is still connected to the module may cause malfunction or damage to the
module or cable.
The cable used for connecting the QD75 external input signal and SSCNET cable should not be
routed near or bundled with the main circuit cable, power cable and/or other such load-carrying
cables other than those for the PLC. These cables should be separated by at least 100 mm
(3.94 in.). They can cause electrical interference, surges and inductance that can lead to mis-
operation.
