Notice:
This is a class A product. In residential areas it may cause radio
interference, in which case the user may be required to take adequate
measures to reduce interference.

PRECAUTIONS FOR SAFE USE
Please observe the following precautions for safe use of the product.
1) Do not use the Amplifier Unit in environments subject to flammable or explosive gases.
2) Do not use the Amplifier Unit in environments subject to exposure to water, oil, chemicals, etc.
3) Do not attempt to disassemble, repair, or modify the Amplifier Unit in any way.
4) Do not apply voltages or currents that exceed the rated ranges.
5) Wire the Amplifier Unit correctly, e.g., do not reverse the polarity of the power supply.
6) Connect the load correctly.
7) Do not short both ends of the load.
8) Do not use the Amplifier Unit if the case is damaged.
9) When disposing of the Amplifier Unit, treat it as industrial waste.
PRECAUTIONS FOR CORRECT USE
Please observe the following precautions to prevent failure to operate, malfunction, or undesirable
effects on product performance.
1) Wire the Amplifier Unit separately from power supply or high-voltage lines. If the Amplifier Unit
wiring is wired together with or placed in the same duct as high-power lines, inductive noise may
cause operating errors or damage the Amplifier Unit.
2
2) Do not extend the cable to more than 30 m, and use a wire size of 0.3 mm or larger for the extension cable.
3) The Amplifier Unit is ready to operate 200 ms after the power supply is turned ON. If the Amplifier Unit and load are
connected to power supplies separately, turn ON the power supply to the Amplifier Unit first.
Please turn on the power supply at the same time when you connecting use the Amplifier Units with cables.
Mutual interference prevention might not operate normally or mobile console might not be able to be used
when the difference between connected Amplifiers at the power supply turning or time is 30ms or more.
4) Always keep the protective cover in place when using the Amplifier Unit.
5) When using a connector model, place a protective label (provided with the E3X-CN series connectors) on
the power supply connecting terminals that are not used, to prevent electric shock or short circuit.
6) When using a communication unit connection model, place a protective cap
(provided with the E3X-ECT/CRT communication unit ) on the connecting
terminals that are not used, to prevent electric shock or short circuit.
7) When connecting or removing the communication unit connection
model, make sure that the connecting part is not slanted.
8) Always turn OFF the power supply before connecting or disconnecting Sensor
Heads, joining or separating Amplifier Units, or adding Amplifier Units.
9) If the data is not written to the EEPROM correctly due to a power failure or
static-electric noise, initialize the settings using the keys on the Amplifier Unit.
Power Supply
10) Using a Mobile Console (The communication unit connection
Connecting Terminal
model cannot use a mobile console.)
Use the E3X-MC11-SV2 Mobile Console for the E2C-EDA-series Amplifier Units. Other Mobile
Consoles, such as the E3X-MC11,E3X-MC11-S, cannot be used.
11) Optical communications are not possible with an E3X-DA-N Amplifier Unit.
12) Depending on the application environment, time may be required for the detection level to stabilize after the power supply is turned ON.
13) Output pulses may occur when the power is interrupted and so turn OFF the power to the load or
load line before turning OFF the power to the Sensor.
14) The Sensor Head of E3C-LDA cannot be used. It may damage, if it connects.
15) When mutual interference prevention is confirmed, the execution time of fine positioning becomes long.
16) Do not use thinners, benzine, acetone, or kerosene for cleaning the Amplifier Unit.
17) A disconnection output may be rarely outputted under the large installation conditions of a detection level also except disconnection.
