3 Electrical Wiring
This chapter describes the procedure for connecting the DGE601A53 with the DGE601A52/DGE601A72, DAIKIN
air conditioners, and other equipment.
Required procedures
• 3.1 Connecting DIII-NET-compatible air conditioners
Equipment-specic procedures
• 3.2 Connecting an emergency stop input device or electric energy meters
WARNING
•Do not turn on the power supply before all wire connections are completed. When there is an earth
leakage breaker or a local switch installed in the circuit, make sure that the circuit is securely inter-
rupted. Otherwise, an electric shock may result.
•The wiring is completed, double-check that all wires are correct before turning on the power supply. If
not connected correctly, there is a possibility of malfunction.
•All wiring must be performed by an authorised electrician.
CAUTION
Be sure to conrm that the power supply cable is not connected to anything except for the unit’s power
supply terminals. If the power supply cable is connected incorrectly, the air conditioner, the DGE601A52/
DGE601A72 or the DGE601A53 will malfunction.
NOTE
You do not need connect to wires to “D+” terminal, “D-” terminal in the [plus ADP IF] section of added
DGE601A53.
These terminals are electrically connected to the slot on left side internally.
3.1 Connecting DIII-NET-compatible air conditioners
3.1.1 Terminals location
To connect the DIII-NET communication line, use the [F1] and [F2] terminals that are located on the front face and
indicated with [DIII]. These 2 terminals do not have polarity.
NOTE
<DIII-NET connecting>
• When connecting multiple wires to the terminal of DIII-NET
Connecting multiple wires to 1 terminal on the DGE601A53 ter-
minal block is not possible.
If you want to connect multiple wires, connect the mark (F1 or
F2) you want to connect to the terminal with the same mark as
shown in the gure on the right.

2 Adding a DGE601A53
This section describes how to add a DGE601A53.
In case of new installation, rst add the DGE601A53 to the DGE601A52/DGE601A72.
After that, install both the DGE601A52/DGE601A72 and DGE601A53.
Preparation of the SLOT
(1) Set the upper and lower DIN rail locks to “Open” position.
(2) Set the upper and lower inter-unit locks of the DGE601A53 to the “UNLOCK” position.

4 Setting addresses for each air conditioner
To control and communicate with the air conditioners, a DIII-NET address needs to be set for each air conditioner.
For detailed instructions on how to set addresses, refer to the “DGE601A52 Installation Manual (3P581074-2)” or
“DGE601A72 Installation Manual (3P581074-6)”.
The installation work of DGE601A53 is complete.
5 Quick Operation Guide
5.1 Restarting the unit
The DGE601A53 can be restarted by pressing the [RESET//] button.
Operate the [RESET//] button using a thin rod or similar item.
Only the slot whose [RESET//] button has been pressed will restart.
CAUTION
Do not perform the operation with a pointed item. Doing so may result in malfunction.

3.2.2 Wiring specications
• Cable type: CPEV cable, FCPEV cable, CVV(S) cable
• Core thickness: CPEV cable, FCPEV cable: φ0.65-0.9 mm, AWG 22-19
CVV(S) cable: 0.75-1.25 mm², AWG 18-16
• Cable length: 200m (656ft.) or less
<Pulse width>
A
B
A Pulse width: 20 to 400ms
B Pulse interval: 100ms or more
CAUTION
•The contact connected to the contact input terminal must be capable of handling 10 mA at 16 V DC.
•If an instantaneous contact is used for triggering an emergency stop, use one that has an energisation
time of 200 ms or more.
NOTE
Once the emergency stop input signal is turned on, all air conditioners stop and do not restart until the emergency
stop input is cleared.

3.1.4 Precautions for using multiple centralized controllers
If multiple centralised controllers are connected on the DIII-NET network, the “MAIN (MASTER)” and “SUB
(SLAVE)” relationship for those controllers.
Set only one of those controllers as MAIN (MASTER), and the other controllers as SUB (SLAVE).
<DIII MASTER>
The [DIII MASTER] switch is located on the front face of the DGE601A52/
DGE601A72. The switch in the [ON] position sets it as “MAIN” and the
switch in the [OFF] position sets it as “SUB”.
3.2 Connecting an emergency stop input device or electric energy meters
3.2.1 Terminals location and schematic connection diagram
Connect the contact input lines or pulse signal lines to the [i1] [i2] [i3] [i4] [CM] terminals of Di located on the upper
part of the front face.

3.1.2 Wiring specications
• Cable type: 2-core vinyl-insulated vinyl-sheathed cable/vinyl cabtyre cable or 2-core shielded cable
• Core thickness: 0.75-1.25mm², AWG 18-16
WARNING
•Do not use multicore cables with 3 or more cores.
•When using a shielded cable, connect only one end of each shield wire to the earth.
•The maximum wire distance must be kept to 1000m (3280ft.) or less, and the total wire length must be
limited to 2000m (6561ft.) or less.
However, when using a shielded cable, the total wire length must be kept to 1500m (4921ft.) or less.
3.1.3 Address setup and termination resistor
For each DGE601A53, a unique address needs to be set.
In case of connecting to the DGE601A51/DGE601A71, set a number between “3” and “8”.
In case of connecting to the iTM, set a number between “2” and “8”.
Use the [PORT] switch located on the front face of each DGE601A53 to set an address. Moreover, the termination
resistor needs to be set for the DGE601A53 which is the furthest from the DGE601A51/DGE601A71 or iTM.
To set the termination resistor, change the position of the [TERM] switch located on the front panel of the DGE601A53
to the [ON] position.

POWER ALV
NOTE
If both the [ALV] and [ALARM] LEDs are lit when powering on the unit after installation, then probably something
went wrong with the PORT (address) assignment:
• You set an invalid PORT address. (In case of DGE601A51/DGE601A71, “0”, “1”, “2”, and “9” are not allowed,
and in case of iTM, “0”, “1”, and “9” are not allowed.)
• You used the same PORT (address) twice.
Check and correct the PORT (address), then power on the DGE601A52/DGE601A72 again and restart.
Check the status of the [ALV] and [ALARM] LEDs.
