[Wiring Precautions]
DANGER
z
Completely turn off the externally supplied power used in the system when installing or
placing wiring.
Not doing so may cause electric shock or damage to the product.
CAUTION
z
Check the layout of the terminals and then properly route the wires to the module.
z
Solder connectors for external device properly.
Insufficient soldering may cause malfunction.
z
Be sure there are no foreign substances such as sawdust or wiring debris inside the
module. Such debris could cause fires, damage, or erroneous operation.
z
The module has an ingress prevention label on its top to prevent foreign matter, such as
wire offcuts, from entering the module during wiring. Do not peel this label during wiring.
Before starting system operation, be sure to peel this label because of heat dissipation.
z
Securely connect the connectors for the drive module to the connectors on the module
and firmly tighten the two screws.
z
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.
z
The cable used for connecting the QD70 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.
