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 Nxm. 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.
