WARNING
● Shut off the external power supply for the system in all phases before connecting or removing a
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.
CAUTION
● Use the programmable controller in an environment that meets the general specifications in the
manual "Safety Guidelines", the manual supplied with the CPU module or head 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. Incorrect interconnection may cause malfunction, failure, or drop of the module.
● Tighten the screw within the specified torque range.
Undertightening can cause drop of the screw, short circuit or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
● Do not directly touch any conductive parts and electronic components of the module. Doing so can
cause malfunction or failure of the module.
WARNING
● After installation and wiring, attach the included terminal cover to the module before turning it on for
operation. Failure to do so may result in electric shock.
CAUTION
● Ground the FG terminal to the protective ground conductor dedicated to the programmable
controller. Failure to do so may result in electric shock or malfunction.
● Tighten the terminal block screw within the specified torque range. Undertightening can cause short
circuit, fire, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, fire, or
malfunction.
● 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.
