DANGER
Turn off all phases of the power supply for the PLC and other external
sources before starting the installation or wiring work.

CAUTION
●
Use the product in the environment within the general specifications
described in the MELSEC L series CPU Module User's Manual. Never use
the product in areas with dust, oily smoke, conductive dusts, corrosive
or flammable gas, vibrations or impacts, or expose it to high tempera-
ture, condensation, or wind and rain.
●
When drilling screw holes or wiring, cutting chips or wire chips should
not enter ventilation slits. Such an accident may cause fire, failure or
malfunction.
●
A protective film is attached onto the module top to prevent foreign
matter such as wire chips entering the module during wiring. Do not
remove the film during wiring. Remove it for heat dissipation before
system operation.
●
Before handling modules, touch a grounded metal object to discharge
the static electricity from the human body. Not doing so may cause
failure or malfunctions of the module.
E
CAUTION
●
Modules must be mounted on a DIN rail.
●
Connect an END cover on the last module on the right side.
●
Do not drop the module or subject it to heavy impact.
●
Do not open or modify a module. Doing so can cause a failure, malfunction,
injury or fire.
●
Do not touch the conductive parts of the module directly.
●
To interconnect modules, engage the respective connectors and se-
curely lock the module joint levers. Incorrect interconnection may
cause malfunction, failure, or drop of the module.
햲
To release the module joint
levers located at the top and
bottom of the L02CPU:
Slide the levers toward the
front side of the module.
햳
Insert the connector of the
power supply module into
that of the CPU module so
that they are securely engaged.
햴
To lock the module joint levers:
Slide the levers toward the
back side of the module.
Make sure that the modules
are securely connected.
