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
Loosen the main unit-xing screw of the product and pull out the
main unit from the socket. Fix the socket on the wall with screws.
Next, insert the main unit into the socket and fasten the main unit
with the main unit-xing screw.

rear of the socket, and then slide the slide lock at the lower part of
the socket upwards until the socket is xed into position as shown
below.

1.3 Mounting Using a Multi-mounting Base
When using a multi-mounting base, see the User’s Manual for
VJCE-01A (VJ Mounting Base for communication) (IM 77J01C51-
11E).
1.4 Using a Duct
When using a wiring duct, install the duct at leaset 30 mm away
from the top and bottom faces of the main unit.
2. INSTALLATION AND ENVIRONMENTAL
CONDITIONS
• Avoid the following environments for installation locations:
Areas with vibrations, corrosive gases, dust, water, oil,
solvents, direct sunlight, radiation, a strong electric eld,
and/or a strong magnetic eld, direct radiant heat, wind,
temperature uctuation.
• 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 the
product and a eld-installed device.
• Use indoors at an altitude of 2000 m or less.
• Operating temperature/humidity range: −10 to 55°C (−10
to 45°C for side-by-side 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/s2or less, 1 oct/min for 90 minutes
each in the three axis directions
• Impact: 98 m/s2or less, 11 ms, 3 axes, 6 directions, 3 times
each
3. EXTERNAL WIRING
WARNING
●To avoid the risk of an electric shock, turn o󰀨 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
ammable or explosive gases or vapors. To do so is
highly dangerous.
●Use of the product ignoring the specications 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
specications.
• The external wiring to the terminals and wiring to
ground are as specications.
Wiring should be connected to the terminals on the socket of
the product. The terminals for external connections are of M3
screws. Use crimp-on terminal lugs for connections to the
terminals.
• Recommended cables: A nominal cross-sectional area of
0.5 mm2 or thicker for signal cables, and that of 1.25 mm2 or
thicker for power cables.

CAUTION
●Do not use output-2 for the isolated single-output
type.
●The power line and input/output signal lines should
be installed away from noise-generating sources.
Other wise accuracy cannot be guaranteed.
●Make sure to earth ground the ground terminal
through minimum resistance. The length and
thickness of the grounding cable should be as
short and thick as possible. Directly connect the
lead from the ground terminal (terminal no. 8) of
the product to the ground. Do not carry out daisy-
chained inter-ground terminal wiring.
●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.
●If the ambient temperature is 50 °C or more, please
use the cable that the rated temperature is 70 °C or
more.
4. MAINTENANCE
The product starts running immediately when the power is turned
on; however, it needs 10 to 15 minutes of warm-up before it
meets the specied performance.
4.1 Calibration Apparatus
• A voltage and current generator (YOKOGAWA GS200 or the
equivalent)
• A digital multimater (YOKOGAWA 7561 or the equivalent)
• A precision resistor of 250 Ω ± 0.01%, 1 W
4.2 Calibration Procedure
1. Connect the instruments as shown below. First adjust the
output-1 signal and then the output-2 signal.

2. Use the DC voltage/current standard and apply input signals
equivalent to 0, 25, 50, 75, and 100% of the input span to the
product.
3. Check to see the corresponding output voltages are 0, 25, 50,
75, and 100% respectively and within the specied accuracy
rating. “R” is used for current output.
• If the output signals are out of the accuracy rating range,
adjust the output signal level using the zero and span
adjustment volumes on front face of the product.
