1.  MOUNTING METHOD

 CAUTION

 

Plug/disconnect the main unit into/from the 

socket vertically to the socket face.  Otherwise the 

terminals may bend and it may cause bad contact.

 

The converter shall not tilt 5 degrees or more in 

either direction when installed.

 

When the converter is not connected to the socket,  

it is necessary to protect the socket against ingress 

of dust to the connector part.

 

Keep this product in a conductive bag when 

plugged out, during transport or storage.

1.1  Wall Mounting

Remove the stoppers (top and bottom) from the product and pull 

out the main unit from the socket. Fix the socket on the wall using 

two M4 screws. Next, insert the main unit into the socket and 

fasten the main unit with the stoppers (top and bottom).

Note:

(1) More than 5 mm interval is 

required for side-by-side

1.2  DIN Rail Mounting 

Insert a DIN rail into the upper part of the DIN rail groove on the 

rear of the socket, and then slide the slide lock at the lower part of 

the socket upwards until the socket is fixed into position as shown 

below.

1.3  Using a Duct

When using a wiring duct, install the duct at leaset 20 mm away 

from the top and bottom faces of the main unit.

2.  INSTALLATION LOCATIONS

 •

Avoid the following environments for installation locations: 

 

Areas with vibrations, corrosive gases, dust, water, oil, 

solvents, direct sunlight, radiation, a strong electric field, 

and/or a strong magnetic field, direct radiant heat, wind, 

temperature fluctuation, 2000 m or more above sea level.

 •

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.

 •

Operating temperature/humidity range: 0 to 50°C (0 to 40°C 

for multiple mounting)/5 to 90%RH (no condensation)

*  If the previous model (style S3.xx earlier) is installed 

together, the ambient temperature is 0 to 40°C.

 •

Continuous vibration: (at 5 to 9 Hz) Half amplitude of 3 mm or 

less (at 9 to 150 Hz) 9.8m/s

2

 or less, 1 oct/min for 90 minutes 

each in the three axis directions

 •

Impact: 98 m/s

2

 or less, 11 ms, 3 axes, 6 directions, 3 times 

each

 •

Install in a place where rigidity is secured.

3.  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 carrying out wiring work.

 

Do not operate the product in the presence of 

flammable or explosive gases or vapors.  To do so is 

highly dangerous.

 

Use of the product ignoring the specifications may 

cause overheating or damage.  Before turning on 

the power, ensure the following:

 

Power supply voltage and input signal value 

applied to the product should meet the required 

specifications.

 

The external wiring to the terminals and wiring to 

ground are as specifications.

 

When disconnecting the main unit from the socket 

with a live wire, it is necessary to install a CT 

protector (CTP-5: sold separately) on the input 

terminal of MB1. However, do not leave the main 

unit unattached from the socket for more than one 

minute even with the CTP-5 installed. If the main 

unit is removed from the socket without the CTP-

5 installed, high voltage will be generated on the 

secondary side of the CT, which may cause burnout 

of the CT and is very dangerous.

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 for signal cables, and that of 1.25 mm

2

 or 

thicker for power cables.
