2. Power supply
WARNING
Be sure to check that the power supply is off in connecting each cable. If the
work is done while the power is on, there may have the case that electric shock
to the operator or even may have damage to the instrument.
WARNING
Before supplying the power, check that the indication of power supply voltage /
specifications for the instrument and the power going to supply should be the
same. If they are not equal, contact us.
If you use the instrument wihout checking them, it may cause a damage in the
instrument or electric shock to the operator.
Earth wire should be grounded securely.
When earth wire is not connected, it may cause a malfunction of the instrument
or electric shock to the operator.
3. Application note
WARNING
Before using a new instrument or exchanging the strain gage applied transducer
for a new one, be sure to make calibration. If calibration will not be made, the
correct measuring results may not be obtained nor which may cause malfunction
in the instrument and there may exist damage in peripheral equipments.
Besides, eve though calibration has been made, there may occur the similar case
when the results are not correct, so make calibration, again.
WARNING
In case of using the instrument, check that the connections are executed properly.
If not connected properly, the correct measuring result will not be obtained,
nor it may cause malfunctions of the instrument, damage to the peripheral
equipments or even more serious accidents.
WARNING
When change of setting is made carelessly on the instrument durning
measurement, correct measured results may not be obtained and it may cause
malfunction in the instrument and even have the possibility of damage in
peripheral insturuments.
WARNING
Do not shock the instrument such as thowing something on it.
If neglected, It may cause destruction of the parts and damage to the electrical
circuits.

4.2 Note on connection
WARING
In case of connection with the instrument, keep strictly to the following items.
If neglected, it may cause an unexpected failure or a damage to the instrument.
 Be sure to set the power supply to OFF, when the connection is made.
 Since the terminal block at the front of the instrument is made of resin, take care not to
drop it down or not to apply strong impact.
 The tightening torque of the screw on the terminal block is 0.8 N・m at the maximum.
 Crimp terminal that suits the terminal block of this unit is shown in the table below.
Width of Crimp terminal Suitable crimp terminal
6.0 mm or less 1.25-3, or Y-type 1.25-3.5
 Connecting cable with the instrument should be away from the noise sourse such as power
supply line and / or I/O line for control and so on as far as possible.
 All of the connections should be excuted securely by referring to the Instruction manual for
the instrument.

WARING
Connection with external control input should be made securely according to the
figures. If neglected, it may cause an unexpected failure and / or malfunction to
the instrument.
 For the connection with external control input / output, be sure to apply shielded
cable, and shielded cable should be connected with the GND terminal (Terminal
No.4 or No.12) If not connected, it may cause malfunction due to the effects from
external noises and so on.
4.3.1 Connection of power supply and ground
Please connect the power supply and the ground (GND) as shown in the figure.
Grounding should be the D class with single earth.
Power supply voltage DC24 V (DC18 V 〜 DC36 V)
Power consumption Approx. 0.15 A (at DC24 V)
WARING
Connections with voltage outputs should be made securely according to the
figures and also within specified load resistance.
If neglected, it may cause an unexpected failure and / or malfunction to the
instrument.
 For the connection with voltage outputs, be sure to apply shielded cable, and
shielded cable should be connected with the F.G. terminal of the instrument. If not
connected, it may cause malfunction due to the effects from external noises and so
on.
