PRECAUTIONS ON SAFETY
Meanings of Signal Words
Indicates a potentially hazardous situation which, if not avoided,
CAUTION
may result in minor or moderate injury or in property damage.
Warning Indications
PRECAUTIONS
Do not use the product with voltage in excess of the rated voltage.
Excess voltage may result in malfunction or fire.
Never use the product with an AC power supply. Otherwise,
explosion may result.
PRECAUTIONS FOR SAFE USE
The following precautions must be observed to ensure safe operation of the Sensor.
• Do not use the Sensor in environments subject to flammable or explosive gases.
• Do not use the Sensor in environments subject to exposure to water, oil, chemicals, etc.
• Do not install the Sensor in environments subject to intense electric field or ferromagnetic field.
• Do not attempt to disassemble, repair, or modify the Sensor Unit in any way.
• Do not apply voltages or currents that exceed the rated ranges.
• Do not use the Sensor in any atmosphere or environment that exceeds the ratings.
• Do not miswire such as the polarity of the power supply.
• Connect the load correctly.
• Do not short both ends of the load.
• Do not use the Sensor if the case is damaged.
• When disposing of the Sensor,treat it as industrial waste.
• Burn injury may occur. The Sensor surface temperature rises depending on application conditions, such as the
ambient temperature and the power supply voltage. Use caution when operating or cleaning the Sensor.
• High-Voltage lines and power lines must be wired separately from this product. Wiring them together or placing
them in the same duct may cause induction, resulting in malfunction or damage.
• When setting the Sensor, be sure to check safety such as by stopping the equipment.
PRECAUTIONS FOR CORRECT USE
• Do not install the Sensor in the following locations.
(1) Locations subject to direct sunlight
(2) Locations subject to condensation due to high humidity
(3) Locations subject to corrosive gas
(4) Locations subject to vibration or mechanical shocks exceeding the rated values
• Use an extension cable with a minimum thickness of 0.3 mm
2
and less than 100 m long.
• Do not apply the forces on the cord exceeding the following limits:
Pull: 40N; torque: 0.1N·m; pressure: 20N; bending: 3 kg
• The Sensor is ready to operate 200 ms after the power supply is turned ON. If the Sensor and load are
connected to power supplies separately, turn ON the power supply to the Sensor first.
• When using a Wire-saving connector type product, 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.
Protective Label
Power Supply Connecting Terminal
• Output pulses may occur when the power supply is turned OFF. Turn OFF the power supply to the load
or load line first.
• Excessive incident light cannot be sufficiently handled by the mutual interference prevention function
and may cause malfunction. To prevent this, set a higher threshold level.
• Make sure that the power supply is turned OFF before connecting, separating or adding Amplifier Units.
• Do not pull or apply excessive pressure or force (exceeding 9.8N) on the Fiber Unit when it is mounted
on the Amplifier Unit.
• The E3X-MC11-SV2 and E3X-MC11-S Mobile Consoles cannot be used.
• Mutual interference prevention does not function among the E3X-DA-N/SD/NA amplifiers. It functions
among E3X-DA-S/MDA models.
• The E3X-DRT21-S, E3X-CRT and E3X-ECT Communication Units cannot be used.
• Always keep the protective cover in place when using the Amplifier Unit.
• Dor not use thinner, benzine, acetone, and lamp oil for cleaning.

Mounting the Ampli er Unit
■ Mounting on DIN Track
1.
Let the hook on the Amplifier Unit's Fiber Unit
connection side catch the track and push the
unit until it clicks.
■ Removing from DIN Track
1.
Fiber Unit Connection Side Hook
Push the unit in the direction 1.
2.
Lift it up in the direction 2.
2
Refer to "1-1. Dimensions" or check the side of
the unit for wire color and role indications.
■ Mounting Ampli er Units in Group
(Wire-saving Connector Type Models)
1.
Mount the Amplifier Units one at a time onto the
DIN track and push them until they click.
Use E3X-CN11 (Master connector) for the master
Amplifier Unit and E3X-CN12 (Slave connector) for
the slave Amplifier Units.
2.
Slide the Ampli er Units in the direction 2.
3.
Use End Plates (PFP-M: separately sold) at the both
ends of the grouped Amplifier Units to prevent them
from separating due to vibration or other cause.
4.
Tighten the screw on the End Plates using a driver.
Up to 16 Amplifier Units can be mounted in a group.
Under environments such as vibration, use an end plate
even with a single amplifier unit.
Tighten the screw while pressing the End Plate.
