1.4 DIN Rail Mounting
Place the converter so that the DIN rail fits into the upper part of
the DIN-rail groove at the rear of the converter, and push until it
clicks. The converter is fixed by a slide lock (at the lower part on
the rear side of the converter).
To remove the converter, pull down the slide lock using a slotted
screw-driver.

2. INSTALLATION LOCATION
z
Avoid the following environments for installation locations:
Areas with vibration, corrosive gases, dust, water, oil, solvents,
direct sunlight, radiation, a strong electric field, and/or a strong
magnetic field, altitude of more than 2000m above sea level.
z
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
converter and a field-installed device.
z
Operating temperature/humidity range: 0 to 50ºC/5 to 90%RH
(no condensation)
3. EXTERNAL WIRING
WARNING
Be sure to turn OFF the power supply before wiring to
avoid the risk of electric shock. Use a tester or similar
device to ensure that no power is being supplied to a
cable to be connected
.
M4 screw terminals are provided for the connection of external
signals. Attach a crimp-on lug to each wire for connection to the
terminals.
z
Recommended cables: A nominal cross-sectional area of 0.5
mm
2
or thicker for signal cables, and that of 1.25 mm
2
or thicker
for power cables.

CAUTION
● This instrument may output a pulse when the power
is turned on/off. Depending on the connected
devices, this pulse output is counted as “one
pulse.”
● Do not connect anything to the terminals that are
not used in the wiring diagram. Otherwise it may
cause the malfunction or damage.
● The power line and input/output signal lines should
be installed away from noise-generating sources.
Otherwise accuracy cannot be guaranteed.
● Adhere strictly to the specifications to avoid
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 specifica -
tions.
(b) The external wiring to the terminals are as specifica -
tions.
● Do not operate the product in the presence of
flammable or explosive gases or vapors.
● The product is sensitive to static electricity;
exercise care in handling. Before you operate the
product, touch a nearby metal part to discharge
static electricity.
