Backside Housing
After connection, the cables should be
fixed with the according strain relief into
the housing.
Installation and commissioning may only be carried out by suitable specialist
personnel. In doing so the respective country-specific regulations (e.g. VDE,
DIN) are to be observed.
1.3.3 LEDs
During normal operation the green LED shows the DCF77 pulse. The yellow LED is on for as
long as signals are emitted via the serial interface.
During an update the green LED flashes in the pulse of the incoming data. In case of error the
yellow LED is on permanently.
