Remote control panel mounting
The remote control panel has the following dimensions:
width 12 cm
height 8 cm.
It can be embedded installed on any boat covering panel, on condition that the area behind is free
of humidity and condense and there is enough depth to house the rear part of the panel (approx. 8
cm.).
Even the computer connecting cable need to run through boat areas not subject to water deposits
(avoid for example to lay the cable through the bilge).
The cut to be performed on the boat covering panel, to encase the remote control panel, has the
following dimensions:
width 9 cm
height 5 cm.
The control panel, once installed, shall be fixed by Parker type screws.
Computer-to-plant wiring
The electric connectors are positioned inside the small electric box connected to the computer
box. The power supply, coming from the service batteries, needs to be connected to the
terminals – and + . The connection to the boat panel needs to be performed downstream the
voltmeter and the ammeter of the boat panelboard. The connecting terminal must be suitable to
support the plant electric load (approx. 150 Watt). A 15A automatic circuit breaker (for 12VDC
systems) must be installed on the power supply , and 10A (for 24VDC systems).
The pumps need to be connected to – 12 , the washing electrovalve must be connected to clamps
– 10, and the pressure switch to 5.
The characteristics of the electric material are:
Automatic circuit breakers: automatic breakers, with 16 amp. cutoff current (for 12 Volts
plants), and 10 amp. (for 24 Volts plants).
Electric cable: red/black single-pole cable, flame-retardant type sea wiring. The cable section is
function of the line length and of the feeding type (12 or 24 Volts).
To calculate the line length it is necessary to add the positive and negative cable runs. Use the
following table once determined these parameters. Choose a bigger cable section in case of
doubt.
