3.2.2 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
CAUTION
• 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.
• Keep at a distance of 50mm or more from power supply cable.
• The maximum wire distance must be kept to 1000m or less, and the total
wire length must be limited to 2000m or less.
However, when using a shielded cable, the total wire length must be kept to
1500m or less.
3.2.3 Precautions for using multiple centralised controllers
“Centralised controller” refers to the equipment (e.g. the DGE601A51) that controls
multiple air conditioners. Besides the DGE601A51, DAIKIN’s product portfolio includes
a wide range of centralised controllers suitable for different applications or building
sizes, which can be used in combination to construct an optimal air conditioning control
system. 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. The switch in the
[ON] position sets it as “MAIN” and the switch
in the [OFF] positions sets it as “SUB”.
