1 Safety Precautions

•Before using the device, thoroughly read the following safety precautions and use as directed.

•Hazards and levels of danger that can occur due to incorrect handling are classified by the following symbols.

Warning	Incorrect handling can result in death, serious injury, etc.
Caution	Incorrect handling can result in injury or damage to the building or its contents.

•After reading this manual, keep this manual for future reference. When the device is reinstalled or repaired, give this manual to those who provide these services. When the user changes, make sure that the new user receives this manual.

WARNING

Ask your dealer or a qualified technician to install the device.

Improper installation by the user may result in electric shock or fire.

Properly install the device on a surface that can withstand the weight of the device.

Device installed on an unstable surface may fall and cause injury.

Only use specified cables. Securely connect each cable so that the terminals do not carry the weight of the cable.

Improperly connected or fixed cables or short-circuited cables may produce heat and/or result in fire.

Do not make any modifications or alternations to the device.

Modifications or improper repair may result in electric shock or fire. Consult your dealer for repair.

Properly install the device according to the instructions in this manual.

Improper installation may result in electric shock or fire.

Have all electrical work performed by an authorized electrician according to the local regulations and instructions in this manual.

Power supply circuit capacity shortage or improper installation may result in electric shock or fire. Ask your dealer or a specialist when performing an electrical work.

Do not move or reinstall the device by yourself.

Improper installation may result in electric shock or fire. Consult your dealer or a specialist when moving or reinstalling the device.

CAUTION

Do not install the device where a flammable gas leak may occur.

If a flammable gas leaks and piles up around the device, it may be ignited and/or explode.

Do not use the device in an unusual environment.

If the device is installed where a large amount of oil (including machine oil), steam or sulfidizing gas is present, this environment may lead the device to a remarkable drop in performance or damage its parts.

Do not install the device where a large amount of steam rises, such as in the bathroom or kitchen.

Avoid installing this device where dew condensation occurs. If the device is installed in such places, it may result in electric shock or malfunctions.

Do not install the device where acidic or alkaline solutions or chemical sprays are used frequently.

Doing so may lead to electric shock or malfunctions.

When installing the device in a hospital, communication station, or similar place, provide sufficient protection against noise.

An inverter equipment, private power generator, high-frequency medical equipment or radio communication equipment may interfere with the normal operation of this device. On the other hand, the device may affect such equipment by creating noise that disturbs medical treatment or image broadcasting.

Do not put tension on the power supply wires.

If tension is put on the wires, they may break and result in excessive heat and/or fire.

Do not immerse the device in water.

Doing so may lead to electric shock or malfunctions.

Do not install the device where the temperature may become more than 40°C [104°F] or less than 0°C [32°F] or it will be subjected to direct sunlight.

If the device is installed in such place, it may result in deformation or malfunctions.

Use standard products with the proper current capacity.

The use of non-standard wires may result in current leak, excessive heat, and/or fire.

Do not touch the main board with hands or tools. Prevent dust from forming on the board.

Doing so may result in fire or malfunctions.

Do not apply an AC power source. The maximum applied voltage for the device is 24 VDC.

Using the incorrect voltage may result in device failure, ignition, and/or fire.

2 Device Capabilities

This device can be used in combination with a system controller to operate/stop general-purpose equipment, as well as to monitor the operating status and error status.

Furthermore, this device is equipped with two sets (channels 1 and 2) of standard terminals and four sets of expansion connectors as the input/output terminals.

In addition to the above, this device also features an interlock function that interlocks M-NET devices for indoor units, etc. set in advance and performs settings such as temperature control and operation/stoppage using the status of contact terminals.

Caution: Usage Restrictions

•We take no responsibility for compensation for damages caused by reasons not attributable to us, for opportunities lost as a result of a failure of this device or an electrical power failure on the customer or any third party site, for damages caused by special circumstances, regardless of whether we can predict them or not, for secondary damages, for accidental damages, or for damages to objects other than this device.

We also take no responsibility for compensation for damages caused by the customer's work, including, but not limited to, replacement work, readjustment of machinery and equipment on the local site, and startup and trial operation.

•Do not use this device for disaster prevention control and security control. (In particular, do not use this device in life critical applications.)

•It is recommended to provide a circuit such as an external switch capable of turning operation on/off from general-purpose equipment in case operation of the general-purpose equipment becomes no longer possible because of a failure of the DIDO controller or a peripheral part.

* This figure omits the power supply line and only shows the transmission line.

•For the shield ground of the M-NET centralized control line, use single-point grounding at the power unit for the transmission line.

However, when supplying electric power to the M-NET centralized control line from the R410A series outdoor unit without using a power supply unit for the transmission line, use single-point grounding at the TB7 of that outdoor unit.

Furthermore, when connecting this device to the M-NET indoor control line, use grounding at the TB3 for each outdoor unit system.

•If this device is connected to the M-NET indoor control line and the outdoor unit is down because, for example, the power supply is interrupted for servicing or there is a failure, the DIDO controller cannot be controlled from the system controller.

•Controlling the system remote controller, ON/OFF remote controller, and schedule timer is only possible with channel 1 of a standard terminal.

•When G(B)-50A is connected, monitoring control can only be performed from G(B)-50A Web or TG-2000A. Monitoring control cannot be performed from the system remote controller, ON/OFF remote controller or schedule timer.
