[Startup and Maintenance Precautions]
CAUTION
● When connecting an external device with a CPU module or intelligent function module to modify data
of a running programmable controller, configure an interlock circuit in the program to ensure that the
entire system will always operate safely. Before executing the other control operations (such as
program modification, parameter change, forced output, or operating status change) of a running
programmable controller, read the relevant manuals carefully for proper and safe operation. Improper
operation can damage machines or cause accidents.
● Especially, when a remote programmable controller is controlled by an external device, immediate
action cannot be taken if a problem occurs in the programmable controller due to a communication
failure. To prevent this, configure an interlock circuit in the program, and determine corrective actions
to be taken between the external device and CPU module when a communication failure.
● Do not disassemble or modify the module. Doing so can cause injury, fire, or failure or malfunction of
the module.
● Use any radio communication device such as a cellular phone or PHS (Personal Handy-phone
System) more than 25cm away in all directions from the programmable controller. Failure to do so can
cause malfunction of the module.
● Shut off all phases of the external power supply used in the system before installing or removing the
module. Failure to do so can cause failure or malfunction of the module.
● After the first use of the product, do not remove/install the module and base unit more than 50 times
(compliant with IEC 61131-2/JIS B 3502). Exceeding the limit may cause malfunction of the module.
● Startup and maintenance of a control panel must be performed by qualified maintenance personnel
with knowledge of protection against electric shock. Lock the control panel so that only qualified
maintenance personnel can operate it.
● The module case is made of plastic. Do not drop the case or expose the case to strong impact. Doing
so can cause damage of the module.
● Before touching the module, be sure to touch such as grounded metal to release the static electricity
from your body. Failure to do so can cause failure or malfunction of the module.
● When cleaning, do not use thinner, benzene, acetone, or kerosene. Doing so can cause damage of
the module.
● Do not insert water or wire through the gaps in the case. Doing so can cause fire or electric shock.
● This product cannot be used as a detector for physical protection. Erroneous output or malfunction
can cause an accident.
● When installing or removing the antenna from the amplifier, first turn off the module power supply.
Failure to do so can cause failure or malfunction of the module.
● Installation of multiple antennas can cause a decrease in communication performance due to mutual
interference. Refer to the description of mutual interference between antennas in the antenna user's
manual.
● In the unlikely event that something is abnormal with the product, stop using the product immediately,
turn off the power supply, and please consult your local Mitsubishi representative. Continued use of
the module in this condition can cause failure and malfunction of the module.
● Do not use the product in locations where chemical products and oil are scattered. Failure to do so
can cause failure or malfunction of the module.
