[WIRING PRECAUTION]
DANGER
! Switch all phases of the external power supply off when installing or placing wiring.
Not doing so may cause electric shock or damage to the product.
CAUTION
! Check the layout of the terminals and then properly route the wires to the module.
! Solder connectors for external 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 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 connectors for the drive module to the connectors on the module
and firmly tighten the two screws.
! Be sure to fix cables leading from the module by placing them in a duct or clamping
them.
Cables not placed in the duct or without clamping may hang or shift, allowing them to be
accidentally pulled, which may cause a module malfunction and cable damage.
! 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/output signal and the drive
module 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.
