Wiring 1-10 V Dimming Lighting Outputs
Each dimmer relay output can provide up to 240 VAC (-WD and -ST models) or 277 VAC (-STP models) (same voltage as power supply - 2 A max per
output, 6 A maximum in aggregate for each module) and 1-10 V commands (sourcing current / sinking current: +/- 5 mA for each output).
The starting current must be kept under 80 A during 20 ms.

Wiring DALI Outputs
Each DALI output can provide up to 240 VAC (same voltage as power supply - 5 A max per output, 10 A maximum in aggregate for each module) and 1
DALI network.
The starting current must be kept under 80 A during 20 ms.
Only for ECx-Light-4DALI-WD: the marking on the external connector is different from the module marking.
Please refer to the table below for the cross reference.

Figure 9: DALI Output Wiring
To save energy, DALI outputs are not powered when the ballasts are turned off. From the moment the command is sent to turn off all the
DALI ballasts connected to the module, there is a 120 second delay before all the outputs are powered off at the same time.
If the outputs are configured in DALI transition mode, the transition time is included in the 120 second delay to power off the outputs.
If all the outputs are configured in DALI transition mode with no dimming, the delay is reduced to 2 seconds.
Wiring High Voltage Shade / Sunblind Outputs
Each high voltage shade / sunblind output can provide up to 240 VAC (same voltage as power supply - 2 A max per output, 8 A maximum in aggregate
for each module) to drive one shade / sunblind motor per output. Only one motor can be driven by each output.
Parallel wiring of shade / sunblind AC motor is strictly forbidden: damage to the motors and/or the installation will
occur.
