Precautions for Safe Use
•
Do not disassemble, repair, or modify the product.
•
When attaching the product to the DIN rail, attach it firmly with
screws.
•
When attaching the product to the DIN rail, ensure that the product
has been attached firmly.
•
If the thickness of a mounting panel is not adequate, or a mistake
has been made during installation, the product may become
disconnected.
•
Ensure that terminal screws have been tightened firmly.
Recommended torque: 0.49 N·m
Assured torque: 0.59 N·m
•
When using the product, ensure that the wiring is correct before
turning on the power.
•
Use a power-supply voltage that is within the range of
specifications.
•
Use the control source and power supply or power lines that
provide inputs with appropriate specifications.
•
Do not install near heat-generating devices (coils, or devices that
use coils).
•
Be sure to confirm terminal numbers for correct wiring.
•
Ensure that wiring is correct. Double-check materials such as
connection charts and circuit diagrams.
•
Properly ground the grounding terminal. Ensure that the common
electrode terminal has been properly grounded. Doing so can
alleviate effects from noise.
•
If electrodes make contact with liquid, purchase and use a
separator to prevent such contact.
•
Keep appropriate distance from devices that generate high-
frequency noise (e.g., high-frequency welders, electronic sewing
machines).
•
Do not turn a setting volume beyond the scope of movement.
•
Do not connect anything to unused terminals.
•
Use SELV power supply with over load protection function for DC
power supply. The insulation of SELV power supply must be a
double or reinforced between input and output. The output voltage
shall be 30 Vr.m.s. and 42.4 V at peak, or use the power supply of
60 V DC max. Recommended power supply: type S8VS-06024

Precautions for Correct Use
For Proper Use
1.
Make sure to use setting values appropriate for the controlled
object. Failure to do so can cause unintended operation, and may
result in accident or corruption of the product.
2.
When discarding, properly dispose of the product as industrial
waste.
3.
Only use this product within a board whose structure allows no
possibility for fire to escape.
4.
To avoid damage to the exterior of the product, do not use organic
solvents (thinner, benzene) or agents with strong alkalinity or
acidity.
About Installation
1.
When wiring, use only recommended crimp terminals.
2.
Do not block areas around the product for proper dissipation of
heat. (If you do not secure space for heat dissipation, life cycle of
the product will be compromised.)
Noise Countermeasures
1.
Do not install the product near devices generating strong high
frequency waves or surges.
2.
When using a noise filter, check the voltage and current and
install it as close to the product as possible.
3.
In order to prevent inductive noise, wire the lines connected to the
product separately from power lines carrying high voltages or
currents. Do not wire in parallel with or on the same cable as
power lines. Other measures for reducing noise include running
lines along separate ducts and using shield lines.
To avoid faulty operations,
malfunctions, or failure, observe the
following operating instructions.
1.
During insulation resistance measurements, never apply the
megohmmeter across the electrode terminals.
2.
Use a power supply that will reach rated voltage within 1 second.
Indicates a potentially hazardous situation
which, if not avoided, may result in minor or
moderate injury or in property damage.
!
CAUTION
!Caution
Do not touch the terminals while power is being supplied.
Doing so may possibly result in electric shock.
