Connecting cables to the battery
DANGER!
Make sure that no cables are short-circuited before connecting the
battery.
WARNING:
The electric power must be turned off during installation.
It is recommended to use a dedicated battery bank for high
ampere consumption equipment such as thrusters, or in
accordance with the engine manufacturer’s recommendations.
Check all high current connections, tighten where necessary.
Connect the plus (
+
) and minus (-) cables to the correct poles
on the battery and the corresponding contacts on the control
unit. The plus (
+
) cable must be connected via the fuse and
main switch.
Always turn off the thruster main switch when not in use.
All cables between the control unit and the electric motor must
be kept as short as possible. Maximum cable length is 1.5 m (5
ft.) Minimum cable insulation rating is 105°C (221°F).
To avoid overheating, all connections between the power cable
and components must be copper to copper (or copper to brass).
No washers of any kind shall be mounted between the power
cable lug and the copper bar/component.
