Wiring connection
The following describes a connection example of Energy Monitoring Relay Interface.
Shield earthing
• The RS-485 communication cable must be earthed on Smart BMS Manager. It does not have to be earthed on
Energy Monitoring Relay Interface.
The shielded wire must be crimped with closed end connector. The shielded wire end must be insulated and left
open.
Connection of power meters
• 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.
(1) Example of contact input connection
(2) Example of contact input connection
CAUTION
• Output sink current has polarity.
When they are connected to inappropriate input terminal, the unit may not operate properly.

Set the Energy
Monitoring Relay
Interface address
with SW1. Assign 1
to 8 to each address
to avoid duplication.
You can set the
Energy Monitoring
Relay Interface
address
independently from
the Digital Input /
Output Relay
Interface address.
CAUTION: The
SW1 setting is read
when the power is
turned on. Push the
reset switch (SW6)
after changing the
address.
Set SW7 as “120 ohm”
on a Energy Monitoring
Relay Interface with
address SW1=1, and
“Open” on the other
interfaces.
The RS-485
communication
cable has polarity
A and B. Be careful
when connecting
the wire.

6Setting
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.
CAUTION
•When the SW1 setting has been changed, push reset switch SW6. The new address setting is read.
•You can set the Energy Monitoring Relay Interface address independently from the Digital Input / Output
Relay Interface address.
• SW2 Operation mode set switch These switches are not used during normal operation.
Set zero (0) or “all OFF”.
• SW3 Test switch
• SW4 Test switch
• SW6 Reset switch
When performing an address setting with SW1, push this reset switch after the address setting to read
the set value.
• SW7 RS-485 terminator resistor select switch
• Set SW7 as “120 ohm” on a Energy Monitoring Relay Interface with address SW1=1, and “Open” on
the other interfaces.
• When a Digital Input / Output Relay Interface is used with these interfaces in the same system,
terminator resistor setting on the Digital Input / Output Relay Interface is not necessary.

7Test run
Before starting test run
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.
Test run
Confirming external input connection
• 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 SW6 to enter the test mode.
Unless SW4 is pushed, the respective input status of DI-1 to DI-4 is indicated by LED2 to LED5.
When SW4 is pushed, the 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 SW6.
Checking the RS-485 communication status
Use LED2 for checking the RS-485 communication status.
When RS-485 communication with Smart BMS Manager is normal, LED2 will blink.
LED2 LED3 LED4 LED5
SW4 OFF Displays DI-1 input status. Displays DI-2 input status. Displays DI-3 input status. Displays DI-4 input status.
SW4 ON Displays DI-5 input status. Displays DI-6 input status. Displays DI-7 input status. Displays DI-8 input status.
Input ON: LED lights
Input OFF: LED turns off
