Cautions on installation
• Use the unit in the environment in accordance with the environmental specifications
described in Paragraph 3.1 in this manual.
Do not use the unit in a place with dust, soot, conductive dust, corrosive gases or
flammable gases. Do not use in places exposed to high temperature, condensation,
wind and rain, vibrations or possible impacts.
If the unit is used in such a place, electrical shocks, fires, malfunction, damage to the
unit or deterioration in the performance of the unit may occur.
• Do not drop cutting chips and electric wire chips into the ventilation window of the PLC
while drilling screw holes or performing the wiring work.
If such chips are dropped, fires, failures or malfunction may occur.
• When the installation work is completed, remove the dust preventive sheet attached to
the ventilation window of the PLC.
If the sheet is not removed, fires, failures or malfunction may occur.
• Connect cables such as extension cables and memory cassettes securely to the
specified connectors respectively.
If such cables and cassettes are not connected correctly, malfunction may occur
caused by imperfect contact.
Note
• When a dust preventive sheet is provided on an extension block,
adhere it on the ventilation window during the installation/wiring
work.
• Never install the unit on the floor, on the ceiling or in the vertical
direction. If the unit is installed in such a way, the temperature
may become too high.
Make sure to install the unit in the horizontal direction as shown
in the figure on the right.
• Arrange extension cables so that connectors on the left side of
extension units, extension blocks, and special units are
connected on the side near the main unit.
• Assure clearance of 50 mm (1.97 inch) or more between the unit
main unit and other equipment or structure. Keep a high voltage
cable, high voltage equipment, and power equipment from the
unit as much as possible.
Cautions on wiring
• Make sure to shut down all the phases of the power supply outside the PLC before
starting the installation/wiring work.
If all the phases are not shut down, electrical shocks or damage to the product may
occur.
• Make sure to attach the terminal covers offered as accessories before supplying the
power and operating the product after the installation/wiring work has been finished.
If the covers are not attached, electrical shocks may occur.
