1. Safety precautions

Before installing the interface unit, make sure you read all the “Safety precautions”.

Please report to your supply authority or obtain their consent before connecting this equipment to the power supply system.

Warning:

Precautions that must be observed to prevent injuries or death.

Caution:

Precautions that must be observed to prevent damages to the unit.

After installation, perform the test run to ensure normal operation. Then explain your customer the “Safety Precautions,” use, and maintenance of the unit based on the information in the Operation Manual provided by local application manufacturer. Both the Installation Manual and the Operation Manual must be given to the user. These manuals must always be kept by the actual users.

:Indicates a part which must be grounded.

Warning:

Carefully read the labels attached to the unit.

Warning:

•The unit must not be installed by the user. Ask an installer or an authorised technician to install the unit. If the unit is installed improperly, electric shock, or fire may be caused.

•For installation work, follow the instructions in the Installation Manual and use tools and pipe components specifically made for use with refrigerant specified in the outdoor unit installation manual.

•The unit must be installed according to the instructions in order to minimize the risk of damages by earthquakes, typhoons, or strong winds. Improperly installed unit may fall down and cause damage or injury.

•The unit must be securely installed on a structure that can sustain its weight. If the unit is mounted on an unstable structure, it may fall down and cause damage or injury.

•All electric work must be performed by a qualified technician according to local regulations and the instructions given in this manual. The unit must be powered by dedicated power lines and the correct voltage and circuit breakers must be used. Power lines with insufficient capacity or incorrect electrical work may result in electric shock or fire.

•Only the specified cables can be used for wiring. Connections must be made securely without tension on the terminals. If cables are connected or installed improperly, It may result in overheating or fire.

•Terminal block cover panel of the unit must be firmly fixed. If the cover panel is mounted improperly, dust and moisture may enter the unit, and it may cause electric shock or fire.

•Make sure to use accessories authorised by Mitsubishi Electric and ask an installer or an authorised technician to install them. If accessories are improperly installed, it may cause electric shock, or fire.

•Do not remodel the unit. Consult an installer for repairs. If alterations or repairs are not performed correctly, it may cause electric shock or fire.

•The user should never attempt to repair the unit or transfer it to another location. If the unit is installed improperly, it may cause electric shock or fire. If the interface unit needs to be repaired or moved, ask an installer or an authorised technician.

•When installing sensors and parts, do not expose the terminals.

1.1. Before installation (Environment)

Caution:

•Do not install the interface unit in outdoor location as it is designed for indoor installation only. Otherwise electric shock or breakdown may be caused by water drop, wind or dust.

•Do not use the unit in an unusual environment. If the interface unit is installed or exposed to steam, volatile oil (including machine oil), or sulfuric gas, or exposed to briny air, the internal parts can be damaged.

•Do not install the unit where combustible gases may leak, be produced, flow, or accumulate. If combustible gas accumulates around the unit, it may cause fire or explosion.

•When installing the unit in a hospital or in a building where communications equipment are installed, you may need to take measure to noise and electronic interference. Inverters, home appliances, high-frequency medical equipment, and radio communications equipment can cause the interface unit to malfunction or to breakdown. At the same time, the noise and electric interference from the interface unit may disturb the proper operation of medical equipment, and communications equipment.

1.2. Before installation or relocation

Caution:
• Be very careful when moving the units. Do not hold the packaging bands.	• Be sure to safely dispose of the packaging materials. Packaging materials,
Wear protective gloves to unpack and to move it, in order to avoid your	such as nails and other metal or wooden parts may cause injury.
hands being injured by parts.	• Do not wash the interface unit. You may receive an electric shock.

1.3. Before electric work

Caution:

•Be sure to install a circuit breaker. If it is not installed, there may be a risk of electric shock.

•For the power lines, use standard cables of sufficient capacity. Otherwise, it may cause a short circuit, overheating, or fire.

•When installing the power lines, do not apply tension to the cables. The cables may be cut or overheated resulting in a fire.

•Make sure to ground the unit. Do not connect the ground wire to gas or water pipes, lightning rods, or telephone grounding lines. If the unit is not properly grounded, there may be a risk of electric shock.

•Make sure to use circuit breakers (ground fault interrupter, isolating switch (+B fuse), and molded case circuit breaker) with the specified capacity. If the circuit breaker capacity is larger than the specified capacity, breakdown or fire may result.

1.4. Before starting the test run

Caution:
• Turn on the main power switch of the outdoor unit more than 12 hours	• Before starting operation, check that all protective parts are correctly in-

2.2. Choosing the interface unit installation location

• Do not install the interface unit in outdoor location as it is designed for indoor	EN
installation only. (The interface board and casing are not waterproof.)
• Avoid locations where the unit is exposed to direct sunlight or other sources of
heat.
• Select a location where easy wiring access to the power source is available.
• Avoid locations where combustible gases may leak, be produced, flow, or accu-
mulate.
• Select a level location that can bear the weight and vibration of the unit.
• Avoid locations where the unit is exposed to oil, steam, or sulfuric gas.
• Do not install in location that is hot or humid for long period of time.

2.3. Installing the interface unit (Fig. 2.3.1, 2.3.2, 2.3.3)

1.Remove 2 screws A from interface unit and remove the cover by sliding it upward (See Fig. 2.3.1).

2.Install the 4 screws (locally supplied) in 4 holes (C hole).

*To prevent the unit from falling off the wall, select the appropriate screws (locally supplied) and secure the base horizontally to the appropriate wall location. (See Fig. 2.3.2)

4.1. Electrical connection

All electrical work should be carried out by a suitably qualified technician. Failure to comply with this could lead to electrocution, fire, and death. All wiring should be according to national wiring regulations.

Connections should be made to the terminals indicated in the following figures.

Use ring terminals and insulate the wires.

Tighten the screw from the bottom terminals first.

Notes:

1.Do not run the low voltage cables through a slot that the high voltage cables go through.

2.Do not bundle power cables together with other cables.

Connect the thermistor for the target temp. to 1 and 2 on the terminal block (TB61)

on the interface controller.

2. HEX inlet temp. thermistor (TH11)

Connect the thermistor for the HEX inlet temp. to 3 and 4 on the terminal block (TB61) on the interface controller.

Connect the thermistor for the 2-phase temp. to 7 and 8 on the terminal block

(TB61) on the interface controller.
When the thermistor cables are too long, cut it to the appropriate length.
Do not bind it in the interface unit.
The 4 thermistors have the same specification except the color of cables, thus we do not specify which thermistor should be	<Photo 4.1.3>
installed to which position.
Notes: When multiple outdoor units are connected, conect thermistors to each interface unit respectively.

Caution:

Do not route the thermistor cables together with power cables.

The sensor part of the thermistor should be installed where user can not access. (It should be separated by the supplementary insulation from areas the user can access.)

4.1.4. Connecting external input

Demand control is available by external input.

Select input type by setting the switch of the interface controller, and it is possible to set capacity request when manual step mode (“Analog input” , “Remote switch” or “Modbus”) is selected. Switch1, Switch 6 : Input selection of inverter capacity setting
