When removing a communication or power cable from the module, do not pull the cable part. For the
cable with connector, hold the connector part connected to the module. When removing the cable
connected to the terminal block, first loosen the screws on the terminal block. Pulling a cable
connected to the module may damage the module and/or cable and cause a malfunction due to poor
contact.
Carefully prevent foreign matter such as wire chips from entering the module.
Failure to do so may cause a fire, breakdown or malfunction of the module.
A protective film is attached onto the module top in order to prevent foreign matter such as wire chips
from entering the module while wiring.
Do not remove this protective film during wiring work. However, be sure to remove it for heat
dissipation before system operation.
