Precautions in Use
● Installation
・ Do not drop, bump, or apply strong shocks to the device or module. It may cause failure.
・ Use your cellular phone or PHS one meter or more away from the product main unit in operation,
various transmission cables, and I/O cable. Otherwise, the system may malfunction.
・ When connecting the connectors and cables or installing the module to the base unit, secure them
with screws tightly.
Insufficient tightening may cause failure or malfunction due to vibrations.
● Power wiring
・ Keep the cables from other lines as much as possible. Especially, keep them away 200mm or more
from power lines.
・ The terminal screw size is M3.5. As applicable crimp contacts, use the one for M3.5 screws whose
width is 5.5mm or less.
・ Do not connect anything to the NC part.
● Use of sample programs
・ Use the sample programs described in the operation manual after performing an operation check.
Make sure to perform an operation check before actual operation to avoid an accident due to
malfunction.
● Battery replacement
・ Battery replacement can be done while the unit is energized or not energized. When replacing the
battery while the unit is not energized, complete the replacement within 3 minutes. If the unit is left
without a battery for a long time, the content of the RAM memory may be lost.
・ The battery voltage is not compatible with manganese batteries or alkaline batteries. Do not mix
them.
・ Do not use a battery when 3 years or more have passed since the purchase date.
● Maintenance
・ Place a module removed from the unit on a conductive mat or conductive bag (used for a backup
board) on a grounded table.
Otherwise, parts may be damaged due to static electricity.
・ Before touching the device or module, touch a grounded metal to discharge the static electricity of
your body. Otherwise, it may cause malfunction or failure due to static electricity.
・ When having the module, having the handle and the ejector of the front panel, do not have a printed
circuit board part directly. The part is damaged by static electricity charged with electricity in the
hand, and it is got shocked by the electric charge that charged the circuit, and the hand might be
hurt by the circuit part.
・ Wipe off stain on the device or module with a soft cloth.
For severe stain, use a wet cloth wrung tightly.
Leaving them stained may cause wrong decision or operational mistake.
・ Do not use benzene or thinner to remove stain on device or module.
It may cause deformation or discoloration of the device panel or module.
