This chapter describes the installation and connection of the L series master/local
modules.
Refer to the following manual.
MELSEC-L CPU Module User's Manual (Hardware Design, Maintenance and
Inspection)
MELSEC-L CC-Link IE Field Network Head Module User's Manual
(1) Before installing or removing the module, shut off the external power supply
for the system in all phases.
Failure to do so may result in electric shock or cause the module to fail or
malfunction.
(2) Use the programmable controller in an environment that meets the general
specifications shown in "Safety Guidelines", the manual supplied with the
CPU module or head module.
Failure to do so may result in electric shock, fire, malfunction, and damage
to or deterioration of the product.
(3) Do not drop the module case and terminal block and do not apply a strong
impact since they are made of resin.
(4) Do not remove the printed-circuit board of each module from its case. This
may cause a failure in the module.
(5) To interconnect modules, engage the respective connectors and securely
lock the module joint levers.
Incorrect interconnection may cause malfunction, failure, or drop of the
module.
(6) Do not directly touch any conductive parts and electronic components of the
module.
Doing so may cause malfunction or failure of the module.
(7) Prevent foreign matter such as dust or wire chips from entering the module.
Such foreign matter can cause a fire, failure, or malfunction.
(8) A protective film is attached to prevent foreign matter, such as wire chips,
from entering the module during wiring. Do not remove this film until the
wiring is complete. Remove it for heat dissipation before system operation.
