Locating the Topside System Components

The SP-III TPU or Rack Mount TPU and the laptop computer or SonarPro
Workstation should be located in an area that is protected from weather and spray
and where the temperatures are consistently between 0°C and 35°C (32°F and
95°F). The SP-III TPU is partially sealed against spray and inclement weather.
However, for equipment longevity, it is best to locate it in a sheltered area. The
location should also be near the towfish launch point or be adequately equipped
with devices for communicating with launch personnel. If separately mounting
components in a 19-inch rack, ensure that the rack is properly secured and that
there is ample room behind it for connecting the cables. A thick layer of foam
should also be placed under the rack for shock isolation, and the back of the rack
should be left open for proper air flow. Support the units inside the rack using
appropriate mounting brackets, shelves or slides as needed and secure the front
panels to the front of the rack where possible using standard 19-inch rack front
panel mounting hardware

Power Requirements

The SP-III TPU requires 88–264 VAC, 47–63 Hz or 12 VDC to operate. For the
laptop computer, refer to its documentation for the power requirements. The Rack
Mount TPU and the SonarPro Workstation require 100–125 or 200–250 VAC,
50–60 Hz power to operate. The Series 4900 Sonar System is designed to protect
against over and under voltage and transient spikes. However, it is always best to
check the power source carefully using a voltmeter or oscilloscope before
operating the equipment.
Since a variety of power connectors are in use throughout the world, it may be
necessary to use an adapter or to cut off the US-type plug on the AC power cord
and re-terminate it with a new plug. Should this modification be required, the
wires should be connected in accordance with Table 3-1.

CAUTION Application of improper AC power may damage the Series
4900 Sonar System. Do not turn the equipment on until the supply voltage
and frequency have been checked.
