[Wiring Instructions]
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 of 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 sure there are no foreign substances such as sawdust or wiring debris
inside the module. Such debris could cause fires, damage, or erroneous
operation.
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.
