Before using the device, carefully read this installation/instruction manual to ensure proper operation.
Keep this manual for future reference and give it to the technician when the device is reinstalled or repaired.
1 Safety Precautions
• Thoroughly read the following safety precautions before use.
• Hazards that can occur from incorrect handling are classified by the symbols below:
Warning Incorrect handling can result in death, serious injury, etc.
Caution Incorrect handling can result in bodily injury and/or structure damage.
• 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
Only a dealer or qualified technician should install, relocate,
reinstall, or repair the device.
Improper installation or repair may result in electrical shock or fire.
Properly install the device on a stable, load-bearing surface.
Device installed on an unstable surface may fall and cause injury.
Only use the specified cables; securely connect each so that the
terminals do not bear any cable weight.
Improperly connected or short-circuited cables may produce heat and
cause a fire.
Do not install the device in a location where a flammable gas leak
may occur.
Gas may leak, collect around the device, ignite, and/or explode.
Do not install the device in environments where large amounts of
oil (including machine), sulfidizing gas, or acidic, alkaline,
chemical sprays are present.
These types of substances may damage internal parts, cause device
performance to be reduced, and cause electrical shock.
When installing the device in a hospital, communication facilities, etc., provide sufficient protection against frequency noise.
Power generators and inverters, high-frequency medical, or radio communication equipment may interfere with the normal operation of this device.
Subsequently, the device may also affect medical treatment, image broadcasting, etc., by creating frequency noise.
Include some slack in the power supply wires.
Tension on the wires may cause them to excessively heat up and/or
break, resulting in a fire.
Do not install the device in a location where there is direct
sunlight or where the temperature may become greater than 40°C
(104°F) or less than 0°C (32°F).
If the device is installed in such place, it may result in deformation or
malfunctions.
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.
All electrical work should be performed by an authorized
electrician according to local regulations and instructions
outlined in this manual.
Capacity shortage to the power supply circuit or improper installation
may result in electrical shock or fire.
Properly install the device according to the instructions in this
Installation/Instruction Manual.
Improper installation may result in electric shock or fire.
CAUTION
Do not install the device in a bathroom, kitchen, or any room
where steam could form. Condensation may develop and cause
electrical shock and/or the device to malfunction.
Use standard wires with the proper current capacity to avoid the
possibility of current leak, excessive heat, and/or fire.
Do not touch the main circuit board; also, make sure that dust
does not accumulate on the circuit board.
Do not immerse the device in water.
Doing so may lead to electric shock or malfunctions.
The maximum applied voltage for the device is 24 VDC - do not
use with an AC power source. (The maximum applied voltage for
the M-NET terminal is 30 VDC.)
Using the incorrect voltage may result in device failure, ignition, and/
or fire.

2 Usage
The AI controller measures temperature and humidity; it also has an alarm capability if the measurement data exceeds
defined setpoints. Historical measurement data can be displayed via only the G(B)-50A Web browser and TG-2000A.
Temperature and humidity cannot be displayed on the G-50A LCD.
Furthermore, an alarm can be output if measurement data exceeds a preset upper or lower limit.
The AI controller also features a function that interlocks M-NET devices for indoor units, etc. set in advance and performs
settings such as temperature control and operation/stoppage using measurement data values.
Caution: Usage Restrictions
• Mitsubishi Electric does not take financial responsibility for damages caused by issues beyond our control or special
circumstances (predicable or unpredictable); and secondary or accidental damages, and damages to other objects. We also
do not take financial responsibility for opportunities lost as a result of device failure, or electrical power failure at the enduser site.
Mitsubishi Electric does not take financial responsibility caused by end-users' requests including, but not limited to, device
testing, startup, readjustment and replacement.
• Do not use this device in disaster prevention security or "critical to life" applications.

* This figure omits the power supply line and only shows the transmission line.
Note:
• 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 the M-NET transmission line of this device to the M-NET indoor control line, use grounding
at the TB3 for each outdoor unit system.
• If the M-NET transmission line of this device is connected to an 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 AI controller cannot be set and
monitored from the system controller.
• The sensor connected to the AI controller can only be monitored from G(B)-50A Web browser and TG-2000A. The sensor
cannot be monitored from the G-50A LCD.
