Battery & cable recommendations:
•
Explanation of electrical table
- All cable lengths are the total of A+B+C+D+E in Fig. 1.
- Battery size is stated as minimum cold crank capacity, not Ah.
- Use slow fuse rated to hold stated Amp-Draw for min. 5 minutes.
•
It is important that you use a good cable size and batteries with a high cranking capacity to feed the thruster, because it is the actual voltage at the
motor while running the thruster that decides the output rpm of the motor and thereby the actual thrust. Please see the list below for advised min.
sizes of cables and batteries. You can of course use larger cables for even better results.
•
A main switch that can take the load without noticeable voltage drop must be installed in the main positive lead so the power for the thruster can be
turned off independent of the rest when not on board or in emergencies. This should be placed in an easy accessible place and the boats instruc
-
tions should inform that this should be turned off like the boat’s other main switches.
•
We also advice to install a fuse in the positive lead for protection against short circuiting of the main cables. This fuse should be of a adequate quality
which normally means that it is physically large as these have less voltage drop than the simple / small ones. It should be of the slow type and sized
to take the amperage draw for at least 5 minutes.
•
It is highly recommended to install a Side-Power Automatic Main Switch 897712 (12V) eller 897724 (24V). The AMS will be activated when the panel
is turned on, contains an automatic short circuit fuse and a manual emergency stop. The AMS will also provide feedback to the panel regarding evt.
faults.
•
The cable ends must be fitted with terminals and these must be well isolated against contact with anything but the proper connection point.
•
Terminals must be properly tightened. Secure/hold inner nut when tightening (Fig. 2). Tighten ø10mm / 3/8" bolt with 15 Nm/11lb/ft.

The Proportional Power Controller PPC800 is a bulkhead
(wall) mounted unit and must be installed in a dry and well
ventilated compartment.The unit also requires a 200mm
minimum head clearance and a 100 mm minimum
clearance surrounding its remaining outer casing.
