A complete thruster system
There are several components in a complete system for your boat; besides the thrusters and tunnels (bow or stern or both) – you will
needcontrolcables,mainswitches–automaticormanual–fuse&fuse-holder,controlpanel(s)andmainpowercables,evenaradio
remote is a normal part of a thruster system today. To simplify installation and further increase the safety, we recommend to use the
original Side-Power Automatic Main switch which also has a built in fuse reducing the number of necessary components. Where the
Automatic Main switch is used, you need a 5 lead control cable between the panel and main switch, while only a 4 lead is needed to
the thruster or if a manual or other auxiliary main switch and separate fuse is used.
The powerful electric motors used on the thrusters require a good electric power supply for safe operation and to achieve the desired
power. Thereby, both the main power cable sizes as well as the available battery capacity is important. It is the actual delivered voltage
at the thruster when it is running, after the voltage drop both in the batteries as well as through the cables, main switch and fuse, that
decides the actual power of the electric motor and thereby the possible thrust. So, getting this right will be important for your prod-
uct satisfaction. It is also important to remember that different types of batteries have different capabilities and specialties, and what is
important for thrusters is the cranking capacity, the batteries ability to deliver a high current for a shorter period of time. On www.
side-power.com you will find a guide called “system builder” – that will guide you through what parts to order as well as recommend
cable sizes and battery capacities for your chosen thruster(s).
The Side-Power “System builder” will help plan the installation in your boat.
