Note: Voltage compensation is possible for AC supplies only.
Section 3.05
Installation
All systems are custom made. Refer to drawings for the specific system for connection
diagram.
Power supplies
The panel should be supplied from two dedicated circuits, one from main distribution board and
one from emergency. The power supplies must be fused.
Dimensioning fuse and cable depends on number and power of navigation lights connected. Add
up power of main navigation lights and add 20W for total power for the system. Note: Main and
spare lights are never on simultaneously, so spare lamps is not necessary to include in calculating
total power. If external transformers are used, take into consideration transformers start up
current when dimensioning fuse.
The panel handles both AC and DC current. When DC current is connected, make sure the phase
is correct.
Navigation lights
The panel is constructed for filament lamps, 25-40W. The panel can be modified for smaller
loads.
Connect according to drawings. Navigation lights should be grounded to the same potential as
the panel.
1.5mm2 cable is suitable in most cases. For long cable lengths the circuit should be voltage
compensated. Refer to section above regarding voltage compensation.
