CHAPTER 3 Preparation for Use
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.
3.3.1
It is important that the Series 5000 V2 Sonar System be well grounded to minimize
potential hazards to the operator and electrical interference from other equipment.
A good ground for the system is a low impedance, well conducted path to sea
water. Always check the quality of the electrical ground by verifying that the AC
power source ground has no voltage potential with respect to the vessel hull.
3.3.2
The main AC power input line is protected by a switch/circuit breaker in both the
TPU and the SonarPro Workstation. The one on the TPU is located on the front
panel on the far right as shown in Figure 3-3 on page 3-12. The one on the
SonarPro Workstation is located on the back panel just to the right of the AC
INPUT connector as shown in Figure 3-2 on page 3-9. To reset a switch/circuit
breaker, switch it to ON.

Towfish Setup
Before connecting the tow cable, make a general inspection of the towfish. Check
that the retaining screws securing the towfish nose cone and tail section assemblies
are tight. Check the tail fins and tow bracket assembly to be sure the retaining
screws and bolts are secure. Also verify that the tail fins are straight and true.
Series 5000 V2 Sonar System Operations and Maintenance Manual
CAUTION Application of improper AC power may damage the Series
5000 V2 Sonar System. Do not turn the equipment on until the supply
voltage and frequency have been checked.
