3. MOUNTING THE MODULES
This section explains how to interconnect modules and how to mount
them on a DIN rail.
POINT
(1) Modules must be mounted on a DIN rail.
(2) Attach an END cover to the right side of the endmost module.
(3) For installation environment and mounting position of the modules, refer to the
following.
MELSEC-L CC-Link IE Field Network Head Module User's
Manual (Hardware Design, Maintenance and Inspection)
3.1
Precautions for Connecting and Mounting Modules
• Do not directly touch any conductive part and electronic
components of the module. Doing so can cause malfunction or
failure of the module.
• After the first use of the module, the number of
connections/disconnections is limited to 50 times. Exceeding the
limit (in accordance with IEC 61131-2) may cause malfunction.
• Do not drop or apply strong shock to the module case or
terminal block connector.
• Do not remove a printed-circuit board of the module from the
case. Doing so may cause failure of the module and/or printed-
circuit board.
• Mounting modules
When installing the programmable controller in a control panel,
fully consider its operability, maintainability, and environmental
resistance. Securely fix all the MELSEC-L series modules used
with the DIN rail. For details on the mounting method, refer to the
MELSEC-L CPU Module User's Manual (Hardware Design,
Maintenance and Inspection).
