Mains connection
In order to fulfil the safety standard (IEC 60950), the mains cable must be routed via the
provided cable clip inside the BDR-510/2 box.

Mains connection
Make sure that each terminal is connected to the corresponding terminal of the mains outlet
(i.e. Phase to Phase, Neutral to Neutral and Earth to Earth). Otherwise malfunction or even
damage to the BED-108/2 will occur.
For specification of mains, refer to
Specifications,
at the end of these instructions.
RS485 (ERNA Camera control) input connection
The RS485 signal is connected to terminal X1.
It is important that the polarity of the connection is correct, otherwise it will not be possible
to obtain control.
Note, the RS485 input is galvanic separated from the rest of the circuit in order to avoid
ground loop problems, therefore:
DO NOT CONNECT THE SCREEN OF THE CABLE TO GROUND/EARTH!
.
RS485 (ERNA Camera control) output connection
The RS485 output signal is connected to the terminals XA1 to XH1.
Power failure connection
If an alarm in connection with mains failure is necessary, the connection can be made to
terminal X3. Potential free contacts are provided for a normally open or normally closed
output.
