This manual describes the installation of the PAC-SF46EPA Transmission booster. For the information about how to install the centralized controller or the air conditioner units, see the installation manual for them. For your safety, first be sure to read “1 Safety Precautions” described below thoroughly and then install the PAC-SF46EPA correctly. After reading this installation manual, keep it in a location that is easy to find, if the PAC-SF46EPA Transmission booster is going to be operated by another person, make sure that this manual is given to him or her.

1 Safety Precautions

• Before installing this unit, make sure you read all the “Safety Precautions”. The “Safety Precautions” provide very important points regarding safety. Make sure you follow them.

Symbols and Terms

WARNING: Statements identify condition or practices that could result in personal injury or loss of life. CAUTION: Statements identify condition or practices that could result in damage to the unit or other property.

Symbols used in the illustrations

: Indicates a part which must be grounded.

: Beware of electric shock. (This symbol is displayed on the Transmission booster label.) <Color: Yellow>

: Please pay attention to electric shock fully because this is not Safety Extra Low-Voltage (SELV) circuit.

ELV

And at servicing, please shut down the power supply for the Transmission booster.

WARNING: Carefully read the labels affixed to the Transmission booster.

Specific Precautions

WARNING

■ Ask your dealer or technical representative to install.

Any deficiency caused by your own installation may result in an electric shock or fire.

■ Install in a place which is strong enough to withstand the weight of the unit.

Any lack of strength may cause the unit to fall down, resulting in personal injury.

■ Wire and connect using the desired cables securely so that any external force from the cable is imparted to the terminal connections.

Imperfect connection and fixing may result in heating or fire.

■ Never modify or repair the unit by yourself.

Any deficiency caused by your modification or repair may result in an electric shock or fire. Consult with your distributor for repair.

■ Make sure that the unit is powered by dedicated line.

Other appearance connected to the same line could cause an overload.

■ Make sure that there is a main power switch.

A ready accessible breaker for power source line helps reduce the risk of electric shocks. Installation of a breaker is mandatory in same areas.

CAUTION

■ Do not install in any place exposed to flammable gas leakage.

Flammable gases accumulated around the body of unit may cause an explosion.

■ Do not use in any special environment.

Using in any place exposed to oil (including machine oil), steam and sulfuric gas may deteriorate the performances significantly or give damage to the component parts.

■ Wire so that it does not received any tension.

Tension may cause wire breakage, heating or fire.

■ Do not wash with water.

Doing so may cause an electric shock or a malfunction.

■ Do not install in any place at a temperature of more than 40°C or less than 0°C or exposed to direct sunlight.

■ Use only a fuse of specified capacity.

A fuse of large capacity or a steel or copper wire could cause a malfunction or fire.

■ Ensure that installation work is done correctly following this installation manual.

Any deficiency caused by installation may result in an electric shock or fire.

■ All electrical work must be performed by a licensed technician, according to local regulations and the instructions given in this manual.

Any lack of electric circuit or any deficiency caused by installation may result in an electric shock or fire.

■ Do not move and re-install the unit yourself.

Any deficiency caused by installation may result in an electric shock or fire. Ask your distributor or special vendor for moving and installation.

■ This appliance must be earthed.

Make sure to install a protective earth(PE)line. Do not connect the protective earth line to gas or water pipes, lighting conductors or telephone grounding lines. Improper grounding may cause an electric shock.

■ The terminal block cover of each line must be firmly attached to prevent entry of dust and moisture.

Improper mounting of cover can cause electric shock of fire.

■ Do not dispose of the PAC-SF46EPA by your self.

■ Do not install in any steamy place such as bathroom or kitchen.

Avoid any place where moisture is condensed into dew. Doing so may cause an electric shock or a malfunction.

■ Do not install in any place where acidic or alkaline solution or special spray are often be used.

Doing so may cause an electric shock or malfunction.

■ Use standard wires in compliance with the current capacity.

A failure to this may result in an electric leakage, heating or fire.

■ Do not touch any PCB (Printed Circuit Board) with your hand or tools. Do not have dust collected on the PCB.

Doing so may cause fire or an electric shock.

■ When installing the unit in a hospital, communication station, or similar place, provide sufficient protection against noise.

The inverter equipment, private power generator, high-frequency medial equipment, or radio communication equipment may cause the air conditioner to operate erroneously, or fail to operate. On the other hand, the air conditioner may affect such equipment by creating noise that disturbs medial treatment or image broadcasting.

NOTES:

• The shield wire of M-NET transmission line shall be grounded by one point earthing method.

• The shield wire shall be connected to the S terminal of the only one unit on the common transmission line.

CAUTION:

• Do not mistake transmission line terminal block 1 (TB2) and transmission line terminal block 2 (TB3) when performing the wiring. The

transmission booster will not operate correctly if the terminal blocks are connected in reverse.

• Since the M-NET transmission line is 30V DC, do not mistake it with the power line when performing the wiring.

(The machine will be broken if the power line is connected to TB2 or TB3.)

• In order to prevent erroneous operations, do not store the power line and M-NET transmission line banded together or in the same conduit.

• Connect the ground wire certainty.

(If the ground wire is not correctly connected, there is a danger of electric shocks or incorrect operations due to the influence of the noise.)

• Never use a megohm tester on the transmission line terminal blocks (TB2 and TB3).
