Modbus Interface Module
· 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.
· All electrical work should be performed by an authorized electrician according to local regulaons and
instrucons outlined in this manual.
Capacity shortage to the power supply circuit or improper installaon may result in electrical shock or fire.
· Do not make any modificaons or alternaons to the device.
Modificaons or improper repair may result in electric shock or fire. Consult your dealer for repair.
· Properly install the device according to the instrucons in this Installaon/Instrucon Manual.
Improper installaon may result in electric shock or fire.
Cauon
· Do not install the device in a locaon 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.
· Do not install the device in a bathroom, kitchen, or any room where steam could form.
Condensaon may develop and cause electrical shock and/or the device to malfuncon.
· Do not install the device in a locaon 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 deformaon or malfuncons.
· When installing the device in a hospital, communicaon facility, etc., provide sufficient protecon
against frequency noise.
Power generators and inverters, high-frequency medical, or radio communicaon equipment may
interfere with the normal operaon of this device. Subsequently, the device may also affect medical
treatment, image broadcasng, etc., by creang frequency noise.
· Include some slack in the power supply wires.
Tension on the wires may cause them to excessively heat up and/or break, resulng in a fire.
· 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 malfuncons.

NOTICE : Modbus Interface Module needs 12~24V DC power to operate.
5. How to install
5.1. Wire Connecons
1. Choose a place where to install the CL-MC03** series. The device provides two mounng holes that
can be used to mechanically affix the case to a solid surface. Double-sided tape may be used to affix
the device. When using tape, ensure that the tape is approved for use within the ancipated
operang temperature ranges.
2. Connect the CL-MC03** cable to the terminals F1/F2 on the indoor unit control board for
communicaon between SASMUNG indoor unit and Cyclogic Modbus Interface Module.
3. Connect the CL-MC03** cable to the terminals V1/V2 on the indoor unit control board for supplying
power.
4. Connect the CL-MC03** cable to the 3rd party controller.
