<Precautions for installation and use> —Safety information
When installing and using a product, you are obligated as an operator to submit official notification, and to install,
construct and utilize the product in compliance with applicable laws and regulations. In order that the product can
be put to safe and reliable use, it is crucial that in addition to fulfilling these legal obligations, you also establish and
implement a safety management system.
This section highlights situations where failure to follow the guidelines
could lead to serious injury or death.
(1) Relocation and Resale
If you intend to relocate or sell your MIURA product, contact your dealer or
MIURA sales office in order that installation work can be carried out correctly
and that the required peripheral equipment may be set up. In addition, ensure
that Operation Manual and the like are kept in order that they may also be
provided to the new owner in the event of resale.
(2) Prohibition of Modification without Permission
Customization or modification not recommended by MIURA may present safety
problems and is therefore prohibited. If you wish to modify the product, contact
your dealer or MIURAsales office in advance. It should be noted that MIURA will
accept no responsibility for the outcome of unapproved customization.
(3) Electrical Work
When connecting a power supply to the product, use wire of the specified
diameter and ensure that the product is correctly grounded. Furthermore, a
dedicated power supply must be used, and an earth leakage circuit breaker
(with overcurrent protection) must be installed.
If this precaution is not observed, serious accidents such as electric shock and
the outbreak of fire may result.
NOTE
(1) Exporting from Japan
Under the Foreign Exchange and Foreign TradeAct, permission must be granted in advance by the Government
of Japan for products under export control to be shipped overseas. In addition, many countries have enacted
regulations and the like covering the import and usage of products from Japan—in certain cases, import and use
of these products is prohibited. Therefore, if you wish to export the product from Japan, contact your dealer or
MIURA sales office in advance.
(2) Product Installation
Ensure that installation work is carried out correctly as set forth in the applicable MIURAInstallation Manual.
Furthermore, anybody who will work with the product should carefully study the content of the Operation Manual
in advance and ensure that it is fully understood.

4. Installation
4.1. Precautions when Installing the Main Unit
•Install in a location within the equipment operating environment range (temperature and humidity).
•Avoid the following locations, which may cause equipment failure.
1) Locations subject to direct sunlight or near equipment that generates heat
2) Hot locations or locations with large temperature fluctuations
3) Locations with high levels of moisture or dust
4) Locations subject to shocks or vibrations
5) Locations in a chemical atmosphere, or locations that may contact chemicals or water
6) Locations near power lines or near equipment that generates strong magnetic fields
7) Locations subject to severe supply voltage fluctuations
•Ensure adequate space to open the door for maintenance work.
•During installation, do not touch any of the internal circuit boards. Do not allow dust or metal
fragments to enter inside the main unit.
CAUTION
Do not directly weld the box onto a column or wall. The
EO-010A/EO-020A contains electrical equipment that may be
damaged by the effects of arc welding.
CAUTION
Observe the following precautions about installation and ensure that
the EO-010A/EO-020A is installed in an appropriate location.
Installation in an inappropriate location may result in equipment
failure.

5. Wiring Work
5.1. Precautions
5.1.1. Wiring Power Supply Line and Installing Earth Leakage Circuit Breaker (with Overcurrent
Protection)
•Use power supply wire with cross-sectional area of AWG#14.
•Connect the grounding phase of the power supply line to the N phase.Always ground the
equipment ground terminal using a wire of the same or larger diameter than the power supply wire.
When performing the grounding work, perform D-type grounding or better.
•Install an earth leakage circuit breaker (with overcurrent protection) in the EO power supply line.
•When installing the earth leakage circuit breaker (with overcurrent protection), do not connect the
overcurrent circuit breaker to the grounding wire.
5.1.2. Precautions when Wiring Communication Line
•Communication line described in this section are the M-NET3 cable line and telephone line.
•Use the communication wires and connectors (terminal processing) specified in Table 2-1.
•Separate the communication wires from power wires and power supply wires and do not pass
them through the same conduit.
Do not pass wires next to high-output equipment that generates strong electrical or magnetic
fields, such as a machine tool.
•Do not use communication wires made by joining multiple wires in order to prevent
communication failure.
•If wires are passed near parts that generate heat of 120F or higher (such as steam piping and
boiler main unit), block the communication wires from the heating parts using insulation materials,
etc. so that the temperature around the wires remains less than 120F.
•Connect the wiring such that water cannot flow along pipes or wires into the main unit.
•Attach a tag indicating the connection destination on both ends of communication wires so that the
equipment to which the wires are connected can be identified.
•When pulling out communication wires from the equipment, do not twist them too much.
•When bundling communication wires, do not tie them too much to avoid deformation.
•When using a cable protector such as a conduit and metal flexible tube, select a protector with an
appropriate size to prevent pressure from being applied to communication wires inside the
protector.
5.1.3. Precautions when Wiring the Antenna Cable (EO-020A)
•Separate the antenna cable from power wires and power supply wires and do not pass them
through the same conduit.
Do not pass the antenna cable next to high-output equipment that generates strong electrical or
magnetic fields, such as a machine tool.
•If the antenna cable is passed near parts that generate heat of 120F.or higher (such as steam
piping and boiler main unit), block the antenna cable from the heating parts using insulation
materials, etc. so that the temperature around the cable remains less than 120F.
•Connect the wiring such that water cannot flow along pipes or cable into the main unit.
•When pulling out the antenna cable from the equipment, do not twist it too much.
•When using a cable protector such as a conduit and metal flexible tube, select a protector with an
appropriate size to prevent pressure from being applied to the antenna cable inside the protector.

5.2. Wiring Procedures
5.2.1. Power Supply Wire and Grounding Wire
1) Requirements
For details about the power supply wires and grounding, refer to “5.1.1 Wiring Power Supply
Line and Installing Earth Leakage Circuit Breaker (with Overcurrent Protection)”.
2) Wiring inside the box
•Connect the power supply wire to the L and N terminals and the main grounding wire to the G
terminal.
•Fix the power supply wire using cable clamps in the box.
•For installing the power supply wire and grounding wire inside the box, refer to “5.3 Wiring
Procedures for Wires inside the Box”.
Figure 5-1: Connection of power supply wire and grounding wire to the terminal block
5.2.2. M-NET3 Cable
1) Requirements
•Ensure that the bending radius of M-NET3 cables is equal to or above the allowable bending
radius recommended by the manufacturer.
If the recommended value is unknown, ensure that the bending radius is at least 8 times the
finished cable outside diameter.
•Ensure that M-NET3 cables are connected to the equipment (between the equipment and hub
and between the hub and hub) no longer than 330’ (100 m).
•Use the M-NET3 cables and connectors specified in Table 2-1.
2) Wiring inside the box
•The M-NET3 cable can be inserted into an arbitrary communication port of the hub. Insert it to
an open communication port.
•Insert M-NET3 cables properly until they are locked with a clicking sound.
•Connect M-NET3 cables perpendicular to avoid stress to the connection port of the hub. If a
LAN cable is not inserted perpendicularly at the connection port (the cable is slanted),
communication failure may occur due to poor connection.
•Fix the cables securely with cable clamps to prevent their own weight from being applied to
them.
•For installing the power supply wire and grounding wire inside the box, refer to “5.3 Wiring
Procedures for Wires inside the Box”.
