2. Power supply
Warning ●Be sure to check that power supply is off when installing each cable.
If the work is done with the power fed, there may have the possibility
of electric shock to the operator or even the possibility of destroying
the instrument.
●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 without checking them, it may cause a
damage in the instrument or electric shock to the operator.
●Grounding wire should be connected securely. When grounding 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 shall not be made, correct measured results may not be
obtained nor it may cause a malfunction in the instrument and there
may exist damage in peripheral equipments.
Besides, even though calibration had been made, there may occur the
similar case when the result is not correct, so make calibration again.
Warning ●In case of using the instrument, check that the connections are
executed properly. If not connected properly, correct measured result
will not be obtained, nor it may cause malfunctions of the instrument,
damage to the peripheral equipments or even worse serious accidents.
Warning ●When change of setting is made carelessly on the instrument during
measurement, it may cause malfunction in the instrument and also
possibility of damage in peripheral equipments.

VI
Warning ●Do not shock the instrument such as throwing something on it.
It may cause the damage to the case and also may cause the damage
to the instrument in resisting to environment.

4−2. Note on connections
Warning ●Keep strictly to the following items in the connection with the
instrument. If neglected, it may cause an unexpected faulty or a
damage in the instrument.
DTurn the power supply OFF when connection is made.
DSince the terminals at the front side of the instrument is made of resin, take care not to
drop it down nor apply strong impact.
DRecommended torque to tighten the terminal screws for terminals is 0.8 N･m at maximum.
DThe crimp−type terminal lugs for the terminals of the instrument are to be applied as
follows：
Width of crimp−type terminal lugs Suitable crimp−type terminal lugs
6.0 mm or less 1.25−3 or Y type 1.25−3.5
DKeep the connecting cable with the instrument away from the noise source like power
supply line and I/O line for control as far as possible.
DConduit wiring should be the type of exclusive one, and avoid using with another line
together.
DAll of the connections should be executed securely according to the Instruction manual.

4−3. Connections
4−3−1. Connection with strain gage applied transducers
The instrument can connect with strain gage applied transducers, such as load cell, pressure
transducer and so on. Here, we will describe the example of connections with load cell, so
connect with another type of strain gage applied transducers in the same way.
※1 When tension is applied with the application of tension type or
universal(compression/tension) type of load cell, and output of “＋”
direction is required, connect “Green” with B terminal, and “Blue”
with D terminal individually. As there is a case which standard
wiring color is different, please confirm the inspection data sheet of
the load cell being used.
※2 When the total length of CAB−502 specifies more than 30 m, the
accuracy may be out of warranty because the resistance of cable
makes the input voltage of the instrument decreased.
※3 When the length of CAB−502 cable is applied more than 10 m, or
when the system is using the zener barrier, the CALIB is not
applicable.

4−3−2. Connection with external control input
Connection of external control input of “A/Z ON”, “A/Z OFF” should be made by using contact
or open collector as below figure.(Effective only when optional Auto zero unit(CSA507C−P99)
is installed.)
Refer to the paragraph 7−2 for each input function.

Warning ●Connection with external control input should be made securely as the
figure indicated. If neglected, it may cause an unexpected trouble or
malfunction on the instrument.
●For the connection with external control input, be sure to apply
shielded cable, and that shield should be connected with GND
terminal. If not connected, it may cause malfunction due to the effect
from external noises and so on.
