Wireless dimming actuator, 4-gang
Switching outputs in parallel
Two to four load outputs can be switched in parallel for the power booster. The output with the
lowest number is the master output, the allocated outputs work as slave. The operation, setting
of the operating mode, basic brightness, switch-on brightness and parameters takes place only
on the master output. The slave outputs receive the settings from the master.
Bus voltage is switched off.
￭ Configure outputs for parallel operation with Mod. switch (5) (see table).

Connect loads to outputs switched in parallel
CAUTION!
Risk of destruction of outputs switched in parallel if the device is set incorrectly.
Dimmer and loads may be destroyed.
In the case of parallel switched outputs, check the device settings and adjust if ne-
cessary before switching on the mains voltage.
CAUTION!
Danger of destruction. 400 V are shorted when outputs switched in parallel are con-
nected to different outer phase conductors.
The device will be destroyed.
Always connect outputs switched in parallel to the same outer phase conductor.
CAUTION!
Risk of destruction: When connecting power boosters to outputs switched in parallel,
there is no guarantee that the dimmer will set the dimming principle suitable for the
load.
Dimmer, power booster and load may be destroyed.
Do not connect any power boosters to outputs switched in parallel.
Only utilize parallel-switched outputs up to 95% each.
The minimum load of parallel switching of outputs is 250 VA.
