Safety Precautions

Definition of Precaution Information

Precautionary Information

■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@

(OMRON made)

Do not keep, install, or use this product

in the following environments.

•Outdoors, or places subject to direct sunlight or wearing weather.

•Places where temperature and humidity exceed the allowable

range of the product specifications.

•Places where there are extreme changes in temperature and

humidity, or icing or condensation may occur.

•Places subject to static electricity or inductive noise.

•Places subject to electrical fields.

•Places where vibrations or physical shocks are strong.

•Places where flammable gasses or flammable liquids exist.

•Places where corrosive gases (in particular, sulfuric or ammonia

gas) exist.

•Places with large amounts of dust or iron powders.

•Places where water or oil come in contact with the product.

•Places subject to salt-water splashes.

■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.

In the interest of product improvement, specifications are subject to change without notice.
