Wiring instruction
Wiring instruction of main & main unit, slave & slave unit.
The main unit can be added up to 32 slave units (The total wire length should be less than 100M).
- The wire connected to the main unit and slave unit must be 2-core RVVSP cable with single wire diameter of 0.2mm2.
Light fixture wiring instruction
The “RS-485 termination resistor switch” of the slave unit is off by default. To make sure stable communication, the “RS-485 termination resistor switch” of the last slave unit is required to turn on.
The slave unit has 4 channels and the channel 1 (L1 In and N1 In) is used to power the slave unit on, which means the slave unit can work normally when the L1 and N1 is connected the power supply. Each input terminal has a single output terminal that the output terminal only provides the power when the corresponding input terminal is connected to the power sublot.
Ensure wiring is correct before power the units on
