Equipotential bonding
The center terminal of the 3 pole terminal block marked is intended for
equipotential bonding.
It is strongly recommended that all interconnected conductive accessible parts in a
system are connected to an equipotential bonding system, in order that no hazardous
touch voltage appears on exposed conductive parts.
5.5
Connection of antenna
The antenna (or other RF source) shall be connected to the input connector marked
“ANT” on the rear edge of the receiver multicoupler top plate by means of a suitable
coax cable.
Be aware that the maximum RF input level of +20 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 included in the equipotential bonding (if used).
5.6
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” or “RX1 to 8” (depending on
model) on the rear edge of the receiver multicoupler top plate.
If the receiver multicoupler has unused RX output ports, these should be terminated
with a 50
Ω
dummy load (min. 250 mW).
5.7
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 housing surface temperature below 50
°
C.
6 Operating instructions
As soon as mains supply voltage or DC supply voltage is applied to PRO-ARU…G,
it will be immediately active.
Normal operational conditions do not require any adjustments or settings of the
multicoupler.
6.1
Power on LED
When power is connected to the PRO-ARU…G, the green power on LED on the
front plate will immediately light and indicate the multicoupler is active.
6.2
Maintenance
No maintenance of the PRO-ARU…G is normally needed.
However, if any malfunction of the multicoupler occurs, please refer to chapter 7:
“Trouble shooting” below.
If the instructions in the Trouble shooting chapter is insufficient, please contact
nearest Amphenol Procom dealer or Amphenol Procom for further information.
