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-specific 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 confirm 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 figure on the right.

When mounting with screws
(1) Remove the upper and lower DIN rail lock screws of the DGE601A53 which is furthest from the DGE601A51/
DGE601A71 or iTM.
(2) Set the upper and lower inter-unit locks to “UNLOCK”.
(3) Pull out the DGE601A53 a little bit.
(4) While pushing the knob attached to the edge of the end cover outward with your finger, pull the end cover off
and remove it.
(5) Return the DGE601A53 to the original position.
(6) Set the upper and lower inter-unit locks to “LOCK”.
(7) Slide in the DGE601A53 to be added along the SLOT rail.
(8) Set the upper and lower inter-unit locks to the “LOCK” position.
(9) Attach the end cover.
(10) Secure all the screw holes on the upper and lower DIN rail locks with screws.

Adding a DGE601A53
This section describes how to add a DGE601A53.
In case of new installation, first 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.
