Installation Instructions BED-108/2
Introduction The BED-108/2 is a distribution unit made for use with simplex RS485 or RS422 signals. The BED-108/2 can be used in connection with all Ernitec Telemetry Receivers series BDR-5XX and BDR-9XX. Using the BED-108/2 it is possible to change a Daisy chain configuration to a Star configuration or a combination of both. BED-108/2 can also be used as a repeater or as a booster for the Telemetry Receivers BDR-51X or BDR-91X which are normally working up to 1200 m. Using the BED-108/2 transmission distance up to 5000 m can be achieved.

BED-108/2 RS-485 Distribution If the box is mounted on a concrete or similar surface, use rawlplugs and galvanised roundhead 1" screws such as no. 8 (ø4.1 x 25 mm). If the box is mounted on a wooden surface, use galvanised roundhead 3/4" screws no. 8 (ø4.1 x 19mm) or similar. When mounted outside, the box should be fixed with the cable glands pointing down.

Installation Instructions BED-108/2
Mains Installation The BED-108/2 must be used with a 3-wire mains connection (2W+PE @ min. 0,75mm 2). Terminals marked with hazardous live symbol requires installation by an instructed person. Details on the mains supply can also be found on a label fitted inside the lid of the BED-108/2. If permanently connected to mains, a readily accessible disconnect device shall be incorporated in the building installation wiring. If pluggable connection to mains, the socket-outlet shall be installed near the equipment and shall be easily accessible. Cable connections It is of utmost importance that all cable connections are carried out, exactly as described in order to avoid malfunction or damage to the BED-108/2, or the connected equipment. All cables to and from the BED-108/2 are fed through the cable glands. Choose an appropriate size gland for the actual cable and tighten the glands when all cables are connected. The choice of cable is important to the optimal function of the BED-108/2.

CE/Safety All electronic equipment can emit or be sensitive to induced electromagnetic noise, which can be conducted by the connected wires or transmitted as electromagnetic fields. Electromagnetic noise can cause malfunction or damage to the equipment. The BED-108/2 are tested to, and fulfils, the following EMC standards: EN 50081-1 (Emission) EN 50130-4 (Immunity) These standards covers equipment installed in an industrial environment. The BED-108/2 fulfil the following safety standard: IEC 60950

Mains - Live Mains - Neutral (Blue) Mains - Earth (Yellow/Green) 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. 3020-00041
