CHAPTER 3 Setup and Test
3.2
Locating the Topside System Components
The TPU or SP-III TPU and the SonarPro Workstation or laptop computer 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.
3.3
Power Requirements
The TPU and the SonarPro Workstation require 100–125 or 200–250 VAC,
50–60 Hz power to operate. 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 Series 4000 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 cable
and re-terminate it with a new plug. Should this modification be required, the
wires should be connected in accordance with Table 3-1.
Series 4000 Sonar System Operations and Maintenance Manual
CAUTION Application of improper AC power may damage the Series
4000 Sonar System. Do not turn the equipment on until the supply voltage
and frequency have been checked.
