For safe operation
Be sure to read this instruction manual before use.
1. Installation place
● Use the instrument where the temperature/humidity specifies with
the range as follows：
Environmental temperature ：−10 ℃ to 50 ℃
Environmental humidity ：Less than 85 %R.H. (Non condensing)
(1) Location where installation is not allowed.
Warning ● Don’t locate the instrument on the places as follows :
It may cause an unexpected faulty in the instrument.
・ Don’t locate the instrument in direct and/or high temperature area.
・ Don’t use the instrument in a high humid area.
・ Don’t install the instrument where there are vibrations and shocks.
・ Don’t use the instrument where there is excess of dusts and fine particles.
・ Don’t use the instrument where there are corrosive gas and salt and like
that.
・ Don’t install the instrument where there is rapid change of temperature
and humidity.
・ Don’t install the instrument near the devices that are magnetized or
generate an electromagnetic field.
・ Don’t install the instrument where the instrument may be affected by
radioactivity or radial rays.
・ Avoid the location where chemical reaction may take place such as in a
laboratory, or like that.
III
(2) Installation
● When installing the instrument, install as referring to the following
figures and secure the space around the instrument.
Each dimensions of the instrument and required dimensions for the environmental
spaces are as follows:
Outline dimensions
Front
Rear
Side
Upper
Panel cut size
Unit：mm

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.
● 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 with Minebea.
If you use the instrument without 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, even 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.
V
Warning ● When change of setting is made carelessly on the instrument during
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 instruments.
Warning ● Do not shock the instrument such as throwing something on it.
If neglected, it may cause destruction of the parts and damage to the
electrical circuits.
Warning ● 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 a damage to the panel switch and even have
the possibility of damage to resist to environments or operational
performances.
Warning ● Don’t 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 a damage to the case and the panel sheet
and even have the possibility of damage to resist to environments or
operational performances.
● 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
clearsheet first.

Warning: The instrument may subject to use in a highly humid area or in full of powder dust.
In such a case, use the instrument by inserting the panel mount gasket attached between the con-
trol panel (cabinet) and the main body
.
By inserting the panel mount gasket, the front panel section becomes IP65 (Inter-
national Protection Code) or equivalent in dust−proof and water−proof construc-
tion.
* Care should be taken when handling the panel mount gasket, since there are up
and down directions.

Warning ● 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.
D Be sure to set the power supply to OFF, when the connection will be made.
D Since the terminal boards at rear side of the instrument is made of resin, take care not to
drop it down or not to apply strong impact.
D Recommended torque to tighten the terminal screws for terminal board should be as
follows：
Torque to tighten
the terminal screws
Terminal board 0.6 N･m
D The suitable crimp type terminal lugs for the terminal board are as follows:
Width of crimp
type terminal lugs
Terminal board 6.2 mm or less 1.25−3 or Y type 1.25−3.5
D Connecting cable with the instrument should be away from the noise source such as power
supply line and/or I/O line for control and so on as far as possible.
D Conduit wiring should be the type of exclusive one, and avoid using with another line
together.
D All of the connections should be executed securely by referring to the Instruction manual
for the instrument.

4−3. Connection
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 the
connection with other type of strain gage applied transducers shall be proceeded in the same
way.
※1 When tension is applied with the application of tension type or
universal(compression/tension) type of load cell, and display of “+”
direction is required, connect “Green” with Terminal No.2 and
“Blue” with Terminal No.4 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 length of CAB−502 is more than 30 m totally, there may
have the case that the accuracy is out of warranty because the
resistance of cable makes the input voltage of the instrument
decreased.

4−3−2. Connection with external control inputs
Connections with external control input “ZERO”,“HOLD”, “PEAK/TRACK” and “RESET”
should be made according to the below figures by using a contact point or an open collector
between the each terminal and terminal No. 8 at “COM.1”
Refer to the paragraph 7−1 for the function of each input.
or
Shield
Warning ● Connections with external control outputs should be made securely
according to the figures. If neglected, it may cause an unexpected
failure and/or malfunction to the instrument.
● For the connections with external control inputs, be sure to apply
shielded cable, and the shielded cable should be connected with GND
terminal of the instrument.(Terminals No.16)
If not connected, it may cause malfunction due to the effects from
external noises and so on.

4−3−3. Connection with contact outputs
Connections with contact outputs “S1” and “S2” and external load should be made by using
each terminal and terminal No. 13 at “COM.2”.
At the same time, take care that the load should not exceed the rated load of contact output.

Warning ● Connections with contact outputs should be made securely according
to the figures and also within the rated capacity of the instrument. If
neglected, it may cause an unexpected failure and/or malfunction to
the instrument.
● For the protection from the contact of the instrument, connect the
surge preventive element that satisfies the characteristics of external
load to connect. If neglected, it may cause unexpected failure and/or
malfunction due to the effects from damage/melt down of the contact
and so on.
● For the connections with contact outputs, be sure to apply shielded
cable, and the shielded cable should be connected with GND terminal
of the instrument.(Terminal No.16)
If not connected, it may cause malfunction due to the effects from
external noises and so on.
