• 3.5 Connecting to equipment which inputs output contact points
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 interrupted. Otherwise, an electric shock
may result.
•
After the wiring is completed, double-check that all wires are connected cor
-
rectly 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

except for the unit’s power supply terminals. If the power supply cable is con

nected incorrectly, the air conditioner or the DGE601A51 will malfunction.
3.1
Connecting DIII-NET-compatible air conditioners
DIIINET is an original DAIKIN air conditioner communication protocol.
Using DIIINET, you can centrally control multiple DAIKIN DIIINETcompatible air condi
tioning devices by connecting them to your DGE601A51.
WARNING
•
Be sure to perform the operation during power-off conditions. Not doing so
may cause an electric shock.
•
To the extent possible, route the high-current cable of the power supply cable
and the low-current cable of the communication cable so that they remain
separate and are not side-by-side.
