[Installation Precautions]
● Use the programmable controller in an environment that meets the general specifications in the Safety
Guidelines included with the MELSEC-L series CPU module. Failure to do so may result in electric
shock, fire, malfunction, or damage to or deterioration of the product.
● To interconnect modules, engage the respective connectors and securely lock the module joint levers
until they click. Incorrect interconnection may cause malfunction, failure, or drop of the module.
● Shut off the external power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may result in damage to the product.
● Do not directly touch any conductive parts and electronic components of the module. Doing so can
cause malfunction or failure of the module.
[Wiring Instructions]
● When connecting a cable with connector to the module, connect the connector part to the module
securely.
● 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.
● When disconnecting the communication and power cables from the module, do not pull the cables by
hand. For the cable with connector, hold the connector part of the cable. Pulling the cable connected
to the module may result in malfunction or 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.
