4.3 Wiring 
The precautions for wiring the Simple Motion module are given below. Refer to this 
section as well as Section 4.1.3 "Handling precautions" when carrying out the work. 
 
4.3.1 Precautions for wiring 
DANGER
 Completely turn off the externally supplied power used in the system before installation or 
wiring. Not doing so could result in electric shock or damage to the product. 
 
CAUTION
 Check the layout of the terminals and then properly route the wires to the module. 
 The external input wiring connector must be crimped or pressured with the tool specified by the 
manufacturer, or must be correctly soldered. Insufficient connections may cause short circuit, 
fire, or 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 films to prevent foreign objects such as 
cable off cuts 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 SSCNET   cable to the bottom connector on the module. 
 When removing the cable from the module, do not pull the cable. Hold the connector 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 external input/output signal cable and the communication 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 100mm (3.94inch) 
or more. They can cause electrical interference, surges and inductance that can lead to mis-
operation. 
 The shielded cable for connecting Simple Motion module can be secured in place. If the 
shielded cable is not secured, unevenness or movement of the shielded cable or careless 
pulling on it could result in damage to the Simple Motion module, servo amplifier or shielded 
cable or defective cable connections could cause mis-operation of the unit. 
 If the cable connected to the Simple Motion module and the power line must be adjacently laid 
(less than 100mm (3.94inch)), use a shielded cable. Ground the shield of the cable securely to 
the control panel on the Simple Motion module side. (A wiring example is given on this section
