5. INSTALLATION
Cautions on installation
•
Use the unit in the environment for the general specifications described in Section 3 in the
manual.
Never use the unit in a place with dust, soot, conductive dusts, corrosive gas or flammable gas,
place exposed to high temperature, dew condensation, rain and wind, or in a place exposed to
vibration or impact.
If the unit is used in such a place, electrical shock, fire, malfunction, damages in the unit or
deterioration of the unit may be caused.
•
Never drop cutting chips or electric wire chips into the ventilation window while drilling screw
holes or wiring cables.
Such chips may cause fire, failure or malfunction.
•
After finishing installation, remove a dust preventing sheet adhered on the ventilation window.
If the sheet remains attached, fire, failure or malfunction may be caused.
Note
✩ During the installation/wiring work, place a dust preventing sheet on the ventilation window.
✩ In order to prevent temperature rise, never install the unit on the floor surface, on the ceiling surface or
in the vertical direction.
Make sure to install the unit on a panel face in the horizontal direction as shown in the figure below.
✩ Use crimp-style terminals of the dimensions shown in the figure below.
✩ Tighten terminals at a torque of 0.5 to 0.8 N m. Securely tighten terminals so that malfunction does not
occur.

6. WIRING
Cautions on wiring
•
Make sure to shut down the power supplies of all phases on the outside before starting instal-
lation or wiring.
If the power supplies are not shut down, you may get electrical shock or the unit may be dam-
aged.
•
Make sure to attach terminal covers offered as accessories before supplying power and start-
ing operation after the installation/wiring work.
•
Correctly supply power to the PLC in accordance with "Cautions on Safety" described in the
manual of the PLC.
If power is not correctly supplied, the unit may be damaged.
•
Connect the wiring of the DC power supply to dedicated terminals as described in this manual.
If the AC power supply is connected to a DC power terminal, the unit may be burnt.
•
Never perform external wiring to unused terminals
•
Perform Class 3 grounding to the grounding terminal in the unit. However, never perform com-
mon grounding (See Section 3) with a strong power system.
[Crimp-style terminal]
•
. Such wiring may damage the unit.
