and/or property damage.

1-1. General precautions

Do not install the controller in areas where large amounts of oil, steam, organic solvents, or corrosive gases (such as ammonia, sulfuric compounds, or acids), or areas where acidic/alkaline solutions or special chemical sprays are used frequently. These substances may significantly reduce the performance and corrode the internal parts, resulting in electric shock, malfunction, smoke, or fire.

To reduce the risk of short circuits, current leak ag e, ele ct r ic shock, malfunction, smoke, or fire, do not wash the controller with water or any other liquid.

To reduce the risk of electric shock, malfunction, smoke, or fire, do not touch the electrical parts, USB memory, or touch panel with wet fingers.

To reduce the risk of injury or electric shock, before spraying a chemical aro un d the controller, stop the operation and cover the controller.

To reduce the risk of injury, keep children away while installing, inspecting, or repairing the controller.

If you notice any abnormality (e.g., burning smell), stop the operation, turn off the controller, and consult your dealer. Continuing the operation may result in electric shock, malfunction, or fire.

Properly install all required covers to keep moisture and dust out of the controller. Dust accumulation and the presence of water may result in electric shock, smoke, or fire.

To reduce the risk of fire or explosion, do not place flammable materials or use flammable sprays around the controller.

To reduce the risk of electric shock or malfunction, do not touch the touch panel, switches, or buttons with a sharp object.

To avoid injury from broken glass, do not apply excessive force to the glass parts. To reduce the risk of injury, electric shock, or malfunction, avoid contact with the sharp

edges of certain parts.

Consult your dealer for the proper disposal of the controller. Improper disposal will pose a risk of environmental pollution.

1-2. Precautions for relocating o r repairing the unit

The controller must be repaired or moved only by qualified personnel. Do not disassemble or modify the controller. Improper installation or repair may result in injury, electric shock, or fire.

1-3. Additional precautions

To avoid discoloration, do not use benzene, thinner, or chemical rag to clean the controller. When the controller is heavily soiled, wipe the controller with a well-wrung cloth that has been so aked in water with mild detergent, and then wipe off with a dry cloth.

This appliance is not intended f or use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.

(5) Operation block setting restrictions

・ An operation block is a collection of groups, and groups of different models (air-conditioning units, LOSSNAY, general equipment,

etc.) can even be set in the same operation block.

・ An operation block that spans AE-200/AE-50/EW-50 systems cannot be set. ・ The operation items differ so we recommend setting operation blocks separately for each of the indoor units, LOSSNAY units,

and A-control models.

・ When peak-cut control is used, blocks become the setting target unit so be sure to set the operation blocks.

(6) Energy management block setting restrictions

・ An energy management block is a collection of operation blocks and OA Processing unit (with interlock control), and operation

blocks of different models (air-conditioning units, LOSSNAY, general equipment, etc.) can also be set in the same energy

management block.

・ An energy management block that spans multiple AE-50/EW-50 in an AE-200 system can be set, but an energy management

block cannot span multiple AE-200 systems.

[2] System Connection Examples

The following shows the equivalent power supply of the AE-200/AE-50/EW-50 and transmission line power supply unit and the equivalent power consumption and the equivalent number of units of the DIDO controller, PI controller, and AI controller. Leave the power jumpers (CN41) of the outdoor units that are connected to M-NET centralized control transmission lines all connected to the CN41 in the same way as they were connected at the time of shipment. If the equivalent power supply is insufficient because system remote controllers and other equipment are connected to the M-NET centralized control transmission lines, transmission line power supply units need to be added. When connecting system remote controllers and other equipment to the M-NET centralized control transmission lines, make sure that the equivalent number of units total will be 40 or less. If the equivalent number of units will exceed 40, add transmission line power supply units so that the equivalent number of units will be 40 or less. To supply M-NET power from a transmission line power supply unit, disconnect the CN21 jumper from the AE-200/AE-50/EW-50.

NOTE: ○ If you remove the service cover from the back of the unit, you will find the power jumper (CN21) of the AE-200/AE-50 in the place

indicated in the figure below.

○ If you remove the service cover from the front of the unit, you will find the power jumper (CN21) of the EW-50 in the place indicated in

[3] Restrictions and Notes on AC Power Supply Wiring

(1) Notes

1. Perform electrical work in accordance with the instructions in the installation manual.

2. To prevent electrical noise from the power supply wiring affecting the wiring for transmission (control), lay the power supply wiring

at least 5 cm (2 in) apart if laying the wiring in parallel.

(Do not insert them in the same conduit.)

3. Be sure to connect the ground wire for protection.

4. Select electrical wiring that meets the requirements in the following table.

Recommended power cable type

VCT, VVF, VVR, or its equivalent

Power cable size 0.75 to 2.00 mm2 (ø1.0 to ø1.6 mm)

[4] Restrictions and Notes on Transmission Wiring

(1) Notes

1. Perform electrical work in accordance with the instructions in the installation manual.

2. To prevent the wiring for transmission (control) from being affected by electrical noise from the power supply wiring, lay the wiring

for transmission (control) at least 5 cm (2 in) apart from the power supply wiring.

(Do not insert them in the same conduit.)

3. Never connect a 100 V or 200 V power supply to the terminal block for the transmission wiring. In the event that a power supply

is connected, the electrical components will burn out.

4. Use a 2-core shielded cable for the transmission wiring. Never use the same cable with multiple cores for wiring multiple systems

because the transmission signals will become unable to be sent and received normally, resulting in erroneous operation.

(2) M-NET transmission line

The type and tolerance of wiring differ depending on the system configuration. Furthermore, if the transmission line is long and there is a noise source within the vicinity of a unit, move the noise source away from the unit to prevent noise interference.

[III System restrictions and notes]

The following shows an example of a wiring diagram for the M-NET transmission line of CITY MULTI.

The example in the figure below shows the cable length limit of centralized control M-NET transmission line and indoor-outdoor M-NET transmission line for each system.

1. Farthest distance for M-NET transmission line (limited by attenuation of the signal waveform) ・ Make the distance between the transmission source and transmission destination of signals no more than 500 m (1640 ft).

If this maximum distance is exceeded, communication will become impossible due to the attenuation of the waveform. a+c+d ≤ 500 m (1640 ft), a+c+e ≤ 500 m (1640 ft), a+b+f ≤ 500 m (1640 ft), c+d+b+f ≤ 500 m (1640 ft), c+e+b+f ≤ 500 m (1640 ft)

2. Maximum power supply distance for M-NET transmission line (limited by voltage drop)

(1) Maximum total length of power feed for the centralized control transmission lines

・ Make the distance between the supply source and supply destination of power no more than 200 m (656 ft).

If this maximum distance is exceeded, communication will become impossible due to the voltage drop. a+c+d ≤ 200 m (656 ft), a+c+e ≤ 200 m (656 ft), a+b+f ≤ 200 m (656 ft)

* If a system remote controller, etc. is connected to the transmission line for centralized control, a power supply unit (PAC-SC 51KUA) is required. * There are cases where the supply source and supply destination of M-NET power differ depending on the setting of the M-NET supply connector.

(2) Maximum total length of power feed for the indoor-outdoor transmission lines

・ Make the distance from an outdoor unit to the supply destination no more than 200 m (656 ft).

c+d ≤ 200 m (656 ft), c+e ≤ 200 m (656 ft)

*1 The wiring length of the M-NET remote controller must be 10 m (32 ft) or less. If 10 m (32 ft) is exceeded, the portion that

exceeds 10 m (32 ft) must be included in the calculations for the maximum total wiring length of the M-NET transmission line (500 m (1640 ft)) and the maximum total power supply distance (200 m (656 ft)).

[III System restrictions and notes]

[6] Restrictions and notes on network wiring

NOTE: When connecting the AE-200/AE-50/EW-50 to t he Internet, be sure to use a VPN router or other security device to prevent unauthorized access.

(1) About LAN

We recommend using 100BASE-TX for the LAN. Also, with regard to the category of LAN cables, use category 5 or better for reasons such as availability and connectivity with optical cables (100BASE-FX). The main cable type is shown in the following table.

LAN standard Cable specification

Maximum wiring length

Communication speed

100BASE-TX

Twisted pair cable (T)

100 m (328 ft)

100 Mbps

(2) About HUB

Use a switching HUB for the HUB.

(3) LAN cable length

The maximum cable length for 100BASE-TX when connecting to the A E-200/AE-50/EW50 is 100 m (328 ft). Therefore, if the LAN cable length exceeds 100 m (328 ft), you can increase the distance between the PC for state monitoring and operation and the AE-200/AE-50/EW-50 by connecting via a switching HUB or other device.

NOTE: For details on the switching HUB, refer the instruction manual supplied with the switching HUB.

There is no limit on the number of switching HUB connections, but if the load on the network becomes extremely high, delays will occur and connecting normally with the network may not be possible. The recommended number of devices, including a HUB, gateway, router, or layer 3 switch, to connect between the AE-200/AE-50/EW-50 is four or less. (The transmission delay time must be 4 seconds or less round trip. If the transmission delay time needs to be checked because, for example, five or more devices are connected, refer to "V [5] 2. About the check method using ping.") If a LAN communication error code appears, check the error as described in "V [5] LAN communication error check procedure."

NOTE:

○ Use commercially available LAN cables.

[9] Other points to note

(1) About using General equipment

・ There may be cases when the general equipment cannot be monitored or operated due to, for example, a disconnection of the

wiring between the general equipment or a failure of the DIDO controller or PLC. In such a case, Mitsubishi Electric will not be held liable in the event of any damages. We recommend providing a circuit that enables emergency remedial operation, etc. to be performed when a failure occurs.

・ With the Ver.1 series of General Control PLC Software, the license number does not need to be registered to the

AE-200/AE-50/EW-50.

・ With the Ver.2 series of General Control PLC Software, General Control PLC Software License is not required to operate and

monitor general equipment and use the schedule functions, but TG-2000A is required. To use interlock control, General Control PLC Software License is required for each AE-200/AE-50/EW-50. General Control PLC Software License is required even for interlock control within the PLC.

・ A license number does not need to be registered to, for example, operate general equipment with a DIDO controller.

(2) About USB memory devices

● Select a USB memory device that meets the following conditions and verify operation several times before use. * Reading and writing with a memory device for which operation has not been verified may cause an unexpected operation.

Therefore, verify operation of the memory device (during trial operation) before use. Do not use a USB memory device for which a data writing error has occurred.

1. USB standard: Supports USB 2.0.

2. Formatted with FAT32 or FAT (FAT16)

3. Security function is not provided or not required to be set.

(Depending on the security function, there may also be some USB devices for which use is possible.) In cases such as when data writing can still not be performed normally when a USB memory device has been replaced with another one after a data error occurs, restart the AE-200/AE-50/EW-50 (turn the power off and then back on) and then perform the check again with a USB memory device other than the one with which the error first occurred.

● Do not remove and insert a USB memory device during writing to a USB memory device. A USB memory device may not be recognized if it is removed and inserted within a short period of time. If that happens, the unit needs to be restarted (turn the power off and then back on).
