Installing the sonar room cables
The sonar room cables include those used to connect the SU90 units to AC mains power, as well as the control cables between the units. A high capacity Ethernet cable connects the topside computer to the transceiver.
Procedure
1 Connect the power cables, but do not apply AC mains to any of the system units.
a Connect the power cable from the uninterruptible power supply (UPS) to the AC power outlet.
b Connect the power cable from the Transceiver Unit to the power outlet on the uninterruptible power supply (UPS).
c Connect the power cable from the internal fans or heat exchanger to the power outlet on the uninterruptible power supply (UPS).
2 Connect the ground cables.
a Connect the ground cable from the Transceiver Unit to vessel ground.
b Connect the ground cable from the hull unit mounting flange to vessel ground.
3 Connect the Ethernet cable from the Processor Unit to the Transceiver Unit.
4 Connect the power cable from the Motor Control Unit to the AC power outlet.
5 Prepare the installation of the transducer cable.
The transducer cable is connected to the Transceiver Unit using a large custom plug.
a Make sure that the transducer cable is long enough to allow the transducer to be lowered and hoisted without causing any damage to the cable, the hull unit, or other equipment in the sonar room.
b DO NOT connect the custom transducer plug to the socket on the Transceiver Unit.
