Bosch Security Systems B.V. Installation manual 2019.11 | V1.00 |
Follow the connection procedure below:
1. Crimp ferrules H onto the ends of the electrical wires of cable F to provide a solid and
reliable electrical connection.
– Use a dedicated crimping tool.
2. Insert each wire into the appropriate slot of the connector B, observing polarity. Wiring
color convention: red for + and black for -.
– Use a flat blade screwdriver to tighten each connection.
3. Insert the cable into the 48V input A, cut the cable to length and mount the connector of
the powering device to the other end of the cable, again observing polarity. Insert this
connector into output A of the powering device.
4. For redundancy, repeat these steps for a second cable between output B of the powering
device to input B of the amplifier.
5. Alternatives:
– Instead of using the A/B outputs of a PRAESENSA powering device, also two
separate power supplies can be used. The maximum current rating of the supply
connectors is 15A; only use a 48V power supply that is current limited to <15A,
also in overload condition.
– When no power supply redundancy is required, a single power supply can be used; in
that case connect the 48V inputs A and B in parallel to make use of the amplifier's
internal dual power converters for fail safe redundancy and to avoid a supply
supervision fault event.
Notice!
The power supply connections may not be longer than 3m
