[Wiring Precautions]
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.
Incomplete connections may cause short circuit, fire, or malfunction.
● Securely connect the connector to the module.
● Place the cables in a duct or clamp them.
If not, dangling cable may swing or inadvertently be pulled, resulting in damage to the module or
cables or malfunction due to poor contact.
● Check the interface type and correctly connect the cable. Incorrect wiring (connecting the cable to an
incorrect interface) may cause failure of the module and external device.
● Tighten the terminal screws within the specified torque range.
Undertightening the terminal screws can cause short circuit or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
● When disconnecting the cable from the module, do not pull the cable by the cable part.
For the cable with connector, hold the connector by hand and pull it out.
For the cable connected to the terminal block, loosen the terminal block screws. Failure to do so may
result in malfunction and damage to the module or cable.
● Prevent foreign matter such as dust or wire chips from entering the module.
Such foreign matter can cause a fire, failure, or malfunction.
● A protective film is attached to the top of the module to prevent foreign matter, such as wire chips,
from entering the module during wiring.
Do not remove the film during wiring.
Remove it for heat dissipation before system operation.
