Ⅰ.Location of installation
Caution
• Install in a location where temperature and humidity conditions are within the ranges described
below.
Environmental temperature-10 ~ 50 Preservation-20 ~ 60 
Environmental humidity85 %RH or less. (Non-condensing)
Warning
• To minimize the risk of unforeseen accidents, avoid installing equipment in the following
locations.
Do not install in the following locations.
• Places exposed to direct sunlight and/or places in the high temperature.
• Places in a highly humid area.
• Places where the instrument is directly affected by vibrations or mechanical
shocks.
• Environments with full of dust or coarse particulates.
• Environments containing of corrosive gas or salt.
• Environments with raid change in temperature and/or humidity.
• Near the devices which generate magnetism or electromagnetic waves.
• Environments vulnerable to radioactivity or radioactivity rays.
• Environments where chemical reaction may take place such as a laboratory.
Please set up into the operation control panel when the instrument is used in
the following places.
• Places where drop of water splashes.
• Places where many dust and fine particles exist.

Ⅲ.Power supply
Warning
• Be sure to check that power supply is OFF when installing each cable. If an operator works
with power ON, operator may have an electric shock or the instrument may be destroyed.
• Before supplying power, check the indication of power voltage/specifications to be identical with
supplied power. If they are not identical, contact with us or our sales agent. Without checking
the above, operation may cause damage to the instrument or electric shock.
Caution
• Be sure to ground a grounding wire.
If a grounding wire is not grounded, it may cause malfunction of the instrument or an electric
shock to an operator.
Ⅳ.Instruction for usage
Caution
• Before using a new instrument, or when exchanging a strain gage applied transducer for a new
one, be sure to make calibration. If neglected, it may cause incorrect results in measurement
or malfunction in the instrument and moreover may cause damage to peripheral equipments.
When similar trouble occurs after calibration, be sure to make calibration again, even if
calibration has completed.
• When using the instrument, check that wires are connected properly. If neglected, correct
measurement cannot be obtained and it may cause malfunction in the instrument or cause
damage to peripheral devices or a critical accident.
• Improper change of setting during operation may cause incorrect measurement or malfunction,
or cause damage to peripheral equipments.
• Do not give the instrument such a shock as throwing something at it. It may cause damage or
destroy electrical circuits and even have loose resistance to environment or operability.
• Do not remove the cover of the case of the instrument, nor peel off the panel sheet nor take the
instrument into pieces. If neglected, it may cause damage to the case and the panel sheet and
even have the possibility of damage to resist to environments or operational performances.
Point!
• At the time of shipment from the factory, the instrument has been plated with a clear
sheet on the panel sheet for protective purpose. In case of application, use the
instrument after removing the clear sheet first.
• Do not push the panel sheet on the instrument with the excessive strong force nor
push it with sharp edge object such as a driver.
• If neglected, it may cause damage to the panel switch and even have the possibility
of damage to resist to environments or operational performances.

Installation & Wiring
2. Installation and Wiring
2-1. Attaching to and Removing from a DIN rail
This instrument adopts the rail mounting type with 35 mm width of DIN standard.
The procedures of attaching and removing are as follows:
Attaching method to a DIN rail
󰴤Hang an upper claw of this instrument on the
upper side of DIN rail.
󰴥Press this instrument onto DIN rail until a click
sound is heard.
󰴦 Confirm the firm fixation.
Removing method from a DIN rail
󰴤 Confirm all the cables including the power
supply cable have come off from the main
body.
󰴥Pull a lower claw of this instrument downward
from the front direction using a screwdriver,
and then remove this instrument from the DIN
rail.
2-2. Note for connecting wires
When connecting wires, turn off the power supply without fail.
Do not supply the electric power until the installation is completed. There is no switch
that switches ON/OFF of power supply in the main body.
Do not drop or do not give the high impact because the terminal block is made by the
resin.
Please separate the cable connected with the main body from the noise source such as I/
O for the control, power supply line as much as possible.
Be sure to connect a grounding wire with exclusive use of D-type single grounding. Do not
share it with other groundings for power supply system.
The tightening torque of terminal screws on the terminal board is 0.6 Nm.
Please use the solderless terminal with 6.2 mm or less in the width.
(O-type 1.25-3 or Y-type 1.25-3)

Installation & Wiring
2-3. Connection with strain gage based transducer
This instrument can connect with the strain gage based transducers, such as load cells,
pressure sensors, etc. Please connect the load cell to the upper terminal block. We describe
here as an example of connection with load cells, and please process it similarly for
connecting with other strain gage based transducers.

Point!
• When tension is applied with the use of tension type or universal (tension/com-
pression) type load cell, and display of (+) direction is required, connect input (+) of
load cell to terminal B and input (-) of load cell to terminal D individually.
(Excluding our load cell, CLS-A, CL- B, UL(A) and UT(A)).
• Cable color is our standard.
(Excluding our load cell, LSM-B series.)

Load cell
Point!
• When the length of CAB-501 (our standard cable) is more than 100 m totally, the
accuracy may be out of warranty as the remote sensing function of the instrument
does not work enough due to the resistance of the cable.
• Shorten the remote sensing input + and remote sensing input - near the main body
of load cell. When the short is made near the instrument, the sensing function does
not work as it is.

Short-bar attached.
Point!
• When you use the 4-wires cable, shorten the load cell terminals A - F with the
attached short-bar. CSD-892B-73 does not work in normal operation when the
terminal F and G is in the open status.
• When the length of CAB-502 (our standard cable) is more than 30 m totally, there
may have the case that the accuracy is out of warranty due to the resistance of
cable, the input voltage of the instrument will be decreased.
• When you use a zener barrier, connect by using above method with 4-wires cable.
