WARNING

CAUTION

• After completion of installation, perform trial operation to check for any problems. Explain method of use and maintenance to the customer by following the descriptions in the manual. Ask customer to keep this Manual at accessible place for future reference.

• Only a qualified installer or qualified service person is allowed to do installation work.

If installation is carried out by an unqualified individual, fire or electric shock may result.

• Perform installation work reliably according to this installation manual. Incomplete installation may cause electric shock, fire or abnormal operation.

• Electrical work must be performed by a qualified installer or qualified service person in accordance with this installation manual. The work must satisfy all local, national and international regulations. Inappropriate work may result in electric shock or fire.

• Connect the specified wires firmly and clamp them securely so that external force applied to the wires does not affect the connector pins. Improper wire connection or clamping may result in fire or malfunction.

• Do not disassemble, modify, repair or move the product yourself. Doing so may cause fire, electric shock, injury or water leaks.

• Ask a qualified installer or qualified service person to do any repairs or to move the product.

3 Installation

1. Before starting installation work, be sure to turn the power supply OFF.

2. Install the "Optional PCB" at the position on the electrical components box shown in the figure on

the right.

3. Install the "Optional PCB" at the specified location inside the electrical components box using the

fixing support.

4. There are four mounting holes for the fixing support at specified locations inside the electrical

components box.

5. Connect the connector (PJ20 (green)) on the "Optional PCB" to the connector (CN511 (green) or

CN514 (green)) on the "interface PCB" using the connector cable (provided). (See figure on right.)

6. The cable (provided) is long. Tie it using the binding band.

5 Details of Operation, Electrical Wiring Diagram

CAUTION

Output Relay (K1, K2, K3) Contact Specifications

• Output terminals (OUTPUT1, 2, 3) must satisfy the following electrical rating.

• When connecting a conductive load (e.g. relay coil) to loads K1, K2 and K3, insert a surge killer CR (for an AC power supply) or a diode for preventing back electromotive force (for a DC power supply) on the bypass circuit.

<Electrical Rating> 220-240 VAC, 10 mA or more, 1A or less 24 VAC, 10 mA or more, 1 A or less (non-conductive load)

Error / Operation output

▼ Functions

The operation error indication PCB can output operation and error states by connecting to the interface PCB of outdoor units.

▼ Operation

Operation output: The operation indication is output when even one of the indoor units in the system

Error output: The error indication is output when an error has occurred on even one of the

Compressor Operation Output (This function is supported only on the SMMS-i.)

▼ Functions

This function can be applied, for example, to the elapsed operation time count of each compressor mounted on an outdoor unit since the compressor in operation signal can be output externally.

▼ Operation

During compressor operation, the relay of the output terminal corresponding to that compressor turns ON (closes) and turns OFF (opens) when compressor operation stops. As shown in the figure, the output terminals are "OUTPUT1", "OUTPUT2" and "OUTPUT3" from the left compressor facing the front of the outdoor unit.

Operating Rate Output (This function is supported only on the SMMS-i.)

▼ Functions

The operation state can be remotely checked since the system operating rate signal can be output externally.

▼ Operation

As shown in the table, each of the output terminals turns ON (relay closes) and OFF (relay opens) according to the system operating rate.
