Notes:
A maximum of 64 DALI devices can be connected on a single DALI network. Each
DALI network must be interconnected with a maximum total wiring of 300m.
A maximum torque of 1.4 Nm should be applied to the screw terminals.
The wire used should be mains rated with double insulation and a minimum
1.5 mm² cross section.
A rubber plug is supplied to close off the unused RJ45 connector. Always ensure
that the plug is installed. The plug stops foreign bodies and dust from entering
the unit.
