<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.

1. Precautions Regarding Installation
When installing the equipment and performing the instrumentation work, take due care of the
following precautions.
1. Perform D-type grounding. When performing the grounding work, connect IV wire or equivalent to
the ground terminal inside the box. Use wire with a diameter equal to or larger than the power
supply wire (AWG #14).
2. Do not install an overcurrent circuit breaker in the grounding wire.
3. Install an independent earth leakage circuit breaker (with overcurrent protection) within 3 m of the
node point in the low-voltage interior wiring.

4. Install an earth leakage circuit breaker (with overcurrent protection) for each phase (L phase and
N phase).
5. Use a power supply wire with insulation resistance of 0.1 MΩ or higher.
6. Use CV wire or equivalent with AWG #14 for the power line. Protect the wire in a conduit.
7. Use MIURA-specified ferrules for connections.
8. Use MIURA-specified communication wires described in this manual.
9. Install the power supply wire (power wire) and communication wire separately.
