Three basic ingredients are needed for a IEC62386 bus:

  • At least 1 Control Device (building automation controller, switch, dimmer…)
  • Up to 64 Control Gear (luminaires or ballasts)
  • Exactly one bus power supply, not two, not three, just one!

Control Devices (Master)

A IEC62386 Control Device sends commands on the bus to control luminaires. This can be a building automation controller, a light switch, a dimmer, or some other interface device that sends commands on the IEC62386 bus. Some Control Devices draw their power supply off the bus, others can supply the bus power. Attention! Read the specifications! Code Mercenaries offers the LED-Warrior09-02MOD that connects two switches to the IEC62386 bus and the LED-Warrior09BT-UP which is a wireless to IEC62386 bridge (compatible with BT 4.0 LE).

Control Gear (Slaves)

IEC62386 compatible luminaires are connected to the bus. They require a separate power supply. There are also ballasts available. Code Mercenaries offers LED-Warrior07-01MOD and LED-Warrior07-02MOD to add IEC62386 to LED drivers, control LED stripes, or other constant voltage LED assemblies.

Bus Power Supply

Exactly one power supply for the bus is required. It has to be a IEC62386 compatible bus power supply. Standard power supplies can damage IEC62386 devices and the bus will not work. Some control devices contain a bus power supply. When using multiple of them it is necessary to make sure no more than 250 mA are supplied to the bus. The bus power supply is only supplying the bus and some control devices with power. Power for the luminaires has to be supplied separately. Code Mercenaries offers the LED-Warrior11 as a simple solution to generate IEC62386 bus power from 24V DC.

How is the wiring done?

All IEC62386 parts are connected in parallel to a two wire connection. The total length of the connections may not exceed 300 m. The cable diameter should be selected as follows:

Until 100m: 0,5 mm²
150m: 0,75 mm²
200m: 1,0 mm²
300m: 1,5 mm²

Cook till done

The last step in a installation is the configuration or deployment. During deployment addresses are assigned to the luminaires and other parameters are set. Building automation controllers usually have a function built in to do this.
