Before using the PI controller, please read this installation/instruction manual carefully to ensure proper operation.
Keep this installation/instruction manual for future reference.
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.
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.
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.
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.
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.
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 counts pulses from a power meter, gas meter, water meter, and calorimeter.
The combined use of the G(B)-50A and TG-2000A allows for calculating the charges for each unit and performing peak-cut
operation (demand control).
.
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.
• We take no responsibility because power volume and gas volume, etc. are converted into the pulses to be captured, and
performance, accuracy, and the like depend on meters.
• Values measured with this device cannot be used for the transaction and certification purposes mentioned in the Measurement
Law.

Installation
Environment
*1: Supply electric power from a power unit for the transmission line or an outdoor unit. Furthermore, the power consumption factor of the M-NET circuitry
of this device is "1/4" (equivalent to one ME Remote Controller).
*2: Supply electric power from the main unit to the contacts of the meters.
If the power is cut, the internal capacitor will normally keep counting the current time for approximately one week.
(The internal capacitor takes approximately a day to charge. Replacement of a battery is not necessary.)

Centralized control line
<Restrictions>
Maximum of 5 units (total of 20 channels) per G(B)-50A
However, the number of units that can be connected to a
G(B)-50A is up to 50 including this device, an indoor unit,
Lossnay unit, etc.
* For the number of units that can be connected when
controlling this device with TG-2000A, refer to the
instruction manual for TG-2000A.

* 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 for central control, 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.
• Connecting an Uninterruptible power supply (UPS) to the 24 VDC power supply is recommended in order to prevent the loss of
pulse data in the event of a power failure.
If a UPS cannot be connected, try to make the AC power supply to the 24 VDC power supply as much same as the power supply
line to the meters.
• This device does not support level meters. To use a level meter, incorporate a Converter circuit externally and convert to pulse
input.
• If 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 PI controller cannot be controlled from the system controller.
