Important
If the device overheats due to extended overload (> 100 °C in housing) it switches off automatically.
The LED is off. The device can be switched on again only after it has been disconnected from the mains
for 60 seconds and has cooled to operational temperature internally.
Eliminate the cause of the overload before switching back on.
When commissioning the device, ensure that the rated current is not continuously exceeded.
The voltage output without choke ( I
2
) is not electrically isolated from the KNX voltage output (I
1
). It may
only be used to power an additional bus line in combination with a separate choke. It may not,
for example, be used to power IP devices (see SELV guidelines).
Devices are designed for continuous operation. They are not approved for frequent switching on and off.
