Precautions for Safety
• Read this “Precautions for Safety” carefully before installation.
• The precautions described below include important items regarding safety. Observe them without fail.
• After the installation work, perform a trial operation to check for any problem. Follow the Owner's
Manual to explain how to use and maintain the unit to the customer. Ask the customer to keep this
Installation Manual together with the Owner's Manual.
• Ask an authorized dealer or qualified installation professional to install or reinstall the relay
interface.
Improper installation may result in electric shock or fire.
• Turn off the main power supply switch or breaker before attempting any electrical work.
Make sure all power switches are off. Failure to do so may cause electric shock.
• Perform installation work properly according to this Installation Manual.
Improper installation may result in electric shock or fire.
• Do not modify the unit.
Any modification may cause a malfunction, resulting in overheating or fire.
WARNING
• Perform wiring correctly in accordance with the specified current capacity.
Failure to do so may result in short-circuiting, overheating, or fire.
• Connect the specified cables for the terminals securely to prevent external forces from
affecting them.
Failure to do so may result in disconnection, overheating, or fire.
CAUTION

securely.
When inserting two RS-485
communication wires into a single
terminal for connection to another
interface, crimp them using the
attached pin terminal.
Power cables/Earth wires/Signal wires
Connection of Power cables/Earth wires/
2 Signal wires
Connect power cables, earth wires, and signal wires to the specified terminals on the terminal block.
The RS-485 signal wire has polarity. Connect A to A, and B to B. If connected with incorrect polarity,
the unit will not work.
CAUTION
Connect the earth
wire to the earth
terminal on the
chassis.

The following describes wiring connections of the Energy Monitoring Relay Interface when it is used in
the air conditioner control system.
•Terminator resistor setting
Set the RS-485 terminator resistor by the TCS-NET Relay Interface.
Do not set it by the Energy Monitoring Relay Interface.
• Shield earthing
The shield earth of the RS-485 signal wires should be single-point earth. Earth the wires on the Touch
Screen Controller side.
Other shield lines should be closed, and the terminal end should be open and insulated.
• Connection of power meter
Use a power meter with a pulse generator.
Connect the non-voltage contact output of the power meter to the Energy Monitoring Relay Interface.
An external input circuit is shown below.
Input signal is electrically isolated by photo-coupler.

Connection diagram
Set the Energy Monitoring Relay
Interface address with SW1. Assign
1 to 4 to each address to avoid
duplication. Each interface has its
own address and can be set
independently.
CAUTION: The SW1 setting is read
when the power is turned on. Push
the reset switch after changing the
address.
Connect the
respective shield
wires of two
cables.
The shield earth of the RS-485
signal wires should be single-point
earth. Earth the wires on the Touch
Screen Controller side. Do not
earth here.
CAUTION: RS-485 signals A
and B have polarity. Be
careful when connecting the
RS-485 wire.
CAUTION: No terminator resistor
setting switch is provided on the
Energy Monitoring Relay Interface.
Set the RS-485 terminator resistor
on the TCS-NET Relay Interface.

When performing a address setting with SW1, push this reset switch after the address setting to
read the set value.
CAUTION
• Set relay interface addresses according to the air conditioner address table.
• When the SW1 setting has been changed, push reset switch SW7. The new address
setting is read.
• You can set the Energy Monitoring Relay Interface address independently from the TCS-
NET Relay Interface address or the Digital Input/Output Relay Interface address.
The following settings are necessary to use Energy Monitoring Relay Interfaces.
• SW1 Address set switch
When two or more Energy Monitoring Relay Interfaces are used, set a different address for each
unit to avoid address duplication.
Assign addresses in an ascending order.
These switches are not used during normal
operation. Set zero (0) or "all OFF".

4 Trial Operation Check
Before starting trial operation
Turn on the power of the Energy Monitoring Relay Interface after all wire connections and settings are
completed. Turn on power of the air conditioning control system.
Trial operation
• Confirming connection to power meters
In the test mode, when the external inputs connected to the input terminals DI-1 to DI-8 are ON, the
respective LEDs will goes on so you can confirm the connection.
Confirming procedure:
Set the operation mode switch SW2 to “3”, and push the reset switch SW7 to enter the test mode.
Unless SW4 is pushed, respective input status of DI-1 to DI-4 is indicated by LED2 to LED5.
When SW4 is pushed, respective input status of DI-5 to DI-8 is indicated by LED2 to LED5.
(*) To return to the normal operation, reset SW2 to “zero (0)” and push SW7.
