4.3 Using a Duct
When using a wiring duct, install the duct at least 20 mm away from the
top and bottom faces of the main unit.
5. INSTALLATION LOCATIONS
● Avoid the following environments for installation locations:
Areas with vibration, corrosive gases, dust, water, oil, solvents, di-
rect sunlight, radiation, a strong electric field, and/or a strong
magnetic field
● If there is any risk of a surge being induced into the power line
and/or signal lines due to lightning or other factors, a dedicated
lightning arrester should be used as protection for both this unit
and a field-installed device.
6. EXTERNAL WIRING
WARNING
To avoid the risk of an electric shock, turn off the power
supply and use a tester or similar device to ensure that no
power is supplied to a cable to be connected, before carring
out wiring work.
Wiring should be connected to the terminals on the socket of the
product. The terminals for external connections are of M3.5 screws.
Use crimp-on terminal lugs for connections to the terminals.
● Recommended cables: A nominal cross-sectional area of 0.5 mm 2
or thicker (0.9 mm 2 or thicker of multicore twisted pair cable with a
shield is recommended) for signal cables, and that of 1.25 mm 2 or
thicker for power cables.

IMPORTANT
● The power line and input/output signal lines should be
installed away from noise-generating sources. Other
wise accuracy cannot be guaranteed.
● The grounding resistance must be 100
Ω
(JIS Class D
grounding). The length of the grounding cable should
be within 20 m. Directly connect the lead from the
ground terminal (terminal no. 6) of the product to the
ground. Do not carry out daisy-chained inter-ground
terminal wiring.
● Use of the product ignoring the specifications may
cause overheating or damage. Before turning on the
power, ensure the following:
(a) Power supply voltage and input signal value applied
to the product should meet the required
specifications.
(b) The external wiring to the terminals and wiring to
ground are as specifications.
● Do not operate the product in the presence of
flammable or explosive gases or vapors. To do so is
highly dangerous.
● The product is sensitive to static electricity; exercise
care in operating it. Before you operate the product,
touch a nearby metal part to discharge static electricity.
