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.
