3 Electrical Wiring
This chapter describes the procedure for connecting the DGE601A52 to the
DGE601A51, DAIKIN air conditioners, and other equipment. In addition to air condition-
ers, the DGE601A52 can connect to a wide range of equipment. However, the required
connection procedures vary depending on the equipment to be connected.
Required procedures
• 3.1 Connecting to the DGE601A51, or equivalent equipment
• 3.2 Connecting DIII-NET compatible air conditioners
• 3.4 Connecting the power supply
Equipment-specic procedures
• 3.3 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 interrupted. Otherwise, an
electric shock may result.
• 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
Be sure to conrm that the power supply cable is not connected to anything
except for the unit’s power supply terminals. If the power supply cable is con-
nected incorrectly, the air conditioner or the DGE601A52 will malfunction.
3.1 Connecting to the DGE601A51, or equivalent equipment
The DGE601A52 is an option for systems featuring the DGE601A51 or iTM, allowing
these systems to control more air conditioners than would otherwise be possible. As an
option, the DGE601A52 cannot be used standalone, and requires a connection to the
DGE601A51 or iTM.
WARNING
• Be sure to perform the operation during power-off conditions. Not doing so
may cause an electric shock.
• Do not clamp high-current cables together with low-current cables.
