Functional earth
The center terminal of the 3-pole terminal block marked
functional earth as well, when needed.
7.6
Connection of alarm
The alarm output provides connection to a relay switch-over contact, which setting
indicates the operating condition of the RF amplifier system.
The alarm output is provided with a 3 pole Phoenix 5.08 mm header/plug.
The Phoenix header/plug is located on the rear side.
See rear view above in section 7.2.
Regarding Phoenix 5.08 mm cable connector, see chapter 9.1: "Spare parts".
7.7
Connection of antenna
The antenna (or other RF source) shall be connected to the input connector marked
"ANT" on the rear edge of the PRO-DAR multicoupler top plate by means of a suitable
coax cable.
Be aware that the maximum RF input level of +23 dBm is not exceeded, in order to avoid
damaging of the RF amplifier.
As the ANT connector shield is connected to chassis, the coax cable shield will
automatically be connected to protective earth and be included in the equipotential
bonding (if used).
7.8
Connection of receivers
The individual receivers' antenna inputs (RF inputs) shall be connected by a suitable coax
cable to the output connectors marked "RX1 to 4", "RX1 to 8" "RX1 to 12" or "RX1 to 16"
(depending on model) on the rear edge of the PRO-DAR multicoupler top plate.
If the PRO-DAR multicoupler has unused RX output ports, these should be terminated
with a 50 dummy load (min. 250 mW).
7.9
Mounting
By rack mounting, screws must be mounted in all 4 mounting holes in the front plate.
When mounted in a fully enclosed cabinet,
adequate ventilation or heat path shall be provided in order to keep the air temperature round
the multicoupler housing below +60 C.
8 Operating instructions
As soon as mains supply voltage or DC supply voltage is applied to a PRO-DAR multicoupler,
it will be immediately active.
Normal operational conditions do not require any adjustments or settings of the multicoupler.
8.1
POWER LED
When power is connected to a PRO-DAR, the POWER LED on the front plate will
immediately light with green color and indicate the multicoupler is active.
8.2
Maintenance
No maintenance of the PRO-DAR models is normally needed.
