Wiring - Mitsubishi QD75M1 User Manual

5. Wiring

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 device
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 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 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 cable 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.
