CAUTION
•
When turning on the power and operating the module after installation and wiring are completed,
always attach the terminal cover that comes with the product.
There is a risk of electric shock if the terminal cover is not attached.
•
Perform correct pressure-displacement, crimp-contact or soldering for external wire connections
using the tools specified by the manufactures.
Incorrect connection may cause short circuits, fire, or malfunction.
•
Attach connectors to the module securely.
•
Be sure to fix communication cables or power supply cables leading from the module by placing
them in the 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.
•
Before connecting the cables, check the type o f interface to be connected.
Connecting or erroneous wiring to the wrong interface may cause failure to the module and
external devices.
•
Tighten the terminal screws within the range of specified torque.
If the terminal screws are loose, it may result in short circuits or malfunction.
If the screws are tightened too much, it may cause damage to the screw and/or the module,
resulting in fallout, short circuits or malfunction.
•
When removing the communication 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.
When removing the cable connected to the terminal block, first loosen the screws on the part
that is connected to the terminal block.
Pulling the cable that is still connected to the module may cause malfunction or damage to the
module or cable.
•
Be careful not to let foreign matters such as sawdust or wire chips get inside the module.
They 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 heat ventilation.
