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.
To reduce the risk of injury, wear protective gear when working on the controller.
Wear protective gear when working on the controller. High-voltage parts pose a risk of
electric shock, and high-temperature parts pose a risk of burns.
1-2. Precautions for unit installation
Do not install the controller where there is a risk of flammable gas leaks. If flammable gas
accumulates around the controller, it may ignite and cause a fire or explosion.
Properly dispose of the packing materials. Plastic bags pose a suffocation hazard to
children.
Take appropriate safety measures against earthquakes to prevent the controller from
causing injury.
To prevent injury, install the controller on a flat surface strong enough to support its
weight.
To reduce the risk of short circuits, current leakage, electric shock, malfunction, smoke, or
fire, do not install the controller in a place exposed to water or in a condensing
environment.
The controller must be installed by qualified personnel according to the instructions
detailed in this manual. Improper installation may result in electric shock or fire.

the power cable to the signal terminal block.
To reduce the risk of malfunction, smoke, fire, or damage to the controller, do not apply a
power supply voltage in excess of that specified.
Properly secure the cables in place and provide adequate slack in the cables so as not to
stress the terminals. Improperly connected cables may break, overheat, and cause smoke
or fire.
To reduce the risk of injury or electric shock, switch off the main power before performing
electrical work.

4
WT07935X04
Electrical work must be performed by qualified personnel in accordance with local
regulations and the instructions provided in this manual. Only use specified cables and
dedicated circuits. Inadequate power source capacity or improper electrical work will
result in electric shock, malfunction, or fire.
To reduce the risk of electric shock, install an overcurrent breaker and an earth leakage
breaker on the power supply. To reduce the risk of electric shock, smoke, or fire, install an
overcurrent breaker for each controller.
Only use properly rated breakers (earth leakage breaker, local switch <switch + fuse that
meets local electrical codes>, moulded case circuit breaker, or overcurrent breaker). The
use of improperly rated breakers or the substitution of fuses with steel or copper wire may
result in electric shock, malfunction, smoke, or fire.
To reduce the risk of current leakage, overheating, smoke, or fire, use properly rated
cables with adequate current carrying capacity.
Proper grounding must be provided by qualified personnel. Do not connect the protective
ground wire to a gas pipe, water pipe, lightning rod, or telephone wire. Improper grounding
may result in electric shock, smoke, fire, or malfunction due to electrical noise
interference.
To reduce the risk of short circuits, electric shock, or malfunction, keep wire pieces and
sheath shavings out of the terminal block.
To reduce the risk of short circuits, current leakage, electric shock, or malfunction, keep
the cables out of contact with controller edges.
To reduce the risk of electric shock, malfunction, or fire, seal the gap between the cable
and the end of the conduit tube with putty.
To reduce the risk of injury, do not touch the burrs of the knockout holes.
1-4. Precautions for relocating or 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.
To reduce the risk of short circuits, electric shock, malfunction, or fire, do not touch the
circuit board with tools or with your hands, and do not allow dust to accumulate on the
circuit board.
1-5. Additional precautions
To avoid damage to the controller, use appropriate tools to install, inspect, or repair the
controller.
To prevent unauthorized access, always use a security device such as a VPN router when
connecting to the Internet.

Any connected air conditioning systems can be operated or monitored on the AE-200A/AE-50A/AE-200E/AE-50E’s
LCD or the Web browser.
By using a PI controller that is built-in on the AE-200A/AE-50A/EW-50A/AE-200E/AE-50E/EW-50E, the energy-
control-related status can be displayed and Peak Cut control can be performed without a use of a PI controller
(PAC-YG60MCA).
Each AE-200A/AE-50A/AE-200E/AE-50E can control up to a total of 50 indoor units and other equipment. By
connecting AE-200A/AE-200E (main controller) andAE-50A/AE-50E/EW-50A/EW-50E (expansion controllers), up
to 200 indoor units and other equipment can be controlled.
AE-50A/AE-50E is not designed to be used alone.
Hereafter, AE-200Aand AE-200E, unless otherwise specified, will be called “AE-200.”
Hereafter, AE-50Aand AE-50E, unless otherwise specified, will be called “AE-50.”
Hereafter, EW-50Aand EW-50E, unless otherwise specified, will be called “EW-50.”
Note: Instead of AE-50A/AE-50E, LCD-less EW-50A/EW-50E can be used as an expansion controller.

6-2-2. M-NET transmission cables (Centralized control transmission cables)
1. Attach M3.5 sleeved ring terminals to the M-NET transmission cables (A, B, Shield).
2. Connect the M-NET transmission cables to the M-NET terminal block.
3. Fix the cables in place with the supplied cable tie.
4. When the power is supplied from the unit other than the AE-200 and AE-50, disconnect the M-NET power jumper from CN21.
Note
ƔProvide a single point ground for the shield of the centralized control transmission cable. (Provide the appropriate grounding
according to local standards.)
ƔWhen leaving the M-NET power jumper connected to CN21 on theAE-200/AE-50/EW-50, the M-NET S (shield) terminal of
TB3 is connected to the ground terminal block on the unit, and the ground is supplied via the protective ground wire.
ƔWhen disconnecting the M-NET power jumper from CN21 on theAE-200/AE-50/EW-50, provide a ground point at a power
supply unit (PAC-SC51KUA).

6-3. Connecting the LAN cable
Connect the LAN cable to the LAN1 port on the AE-200/AE-50. (The LAN2 port is exclusively used for BACnet®
function.)
ƔThe LAN cable is not supplied. Use a category 5 or above straight LAN cable.
ƔUse a switching HUB compatible with 100 BASE.
ƔThe maximum distance between the switching HUB and AE-200/AE-50/EW-50 is 100 m (328 ft).
ƔThe recommended number of connected devices such as gateway, router, layer 3 switch, or HUB between the
AE-200/AE-50/EW-50 is four or less. (Transmission round-trip delay time must not exceed one second. If the transmission
delay time is long, a communication error may be detected. Check the transmission delay time, referring to section 6-4.)
Note
ƔLAN must be installed before the unit installation. Route the LAN cable to the AE-200/AE-50 in the same way as the M-NET
transmission cables.
ƔWhen connecting the AE-200/AE-50 to an existing LAN, consult the system administrator to decide the IP address. Change
the IP address setting before connecting the LAN cable to the LAN1 port.
ƔTo prevent unauthorized access, always use a security device such as a VPN router when connecting the AE-200/AE-50 to
the Internet.
6-4. Confirming the LAN transmission delay time
Connect a monitoring PC to a device such as HUB that is connected to the AE-200. Send a command from the PC
to the AE-50, and receive the response from theAE-50. Check the time between sending and receiving on the PC
display.
