Note:
•
To install the underwater light on the steel hull it is highly recommended to use the
optional isolation board (not included) between the hull and underwater light casing to
prevent galvanic corrosion.
Note:
•
Do not overtighten the screws M8 as this can result in hull or underwater light damage.
Bonding
The underwater light has to be connected to the vessels bonding and cathodic protection using a pre-
tinned wire a minimum of 8 AWG (8.36 mm
2
) with green insulation or green with a yellow stripe. The
wire has to be connected to the underwater light by the help of the bonding screw M4 located on the
fixing nut.
Note:
•
It is highly recommended to paint the entire underwater casing exposed to the water with
anti-foul paint.
Power Supply Unit MPS021000 / MPS021500
The MPS021000 / MPS021500 has to be installed near the underwater light inside of the vessel.
Avoid the installation in extremely hot places and near appliances generating strong magnetic fields.
An extension cable can be used in case of longer distance between the underwater light and the
power supply unit but with suitable length and thickness.
The installation have to be realized by a qualified personnel.
Note:
•
The main DC power supply of the vessel has to be switched off before installation.
Power supply connection
The power supply has to be connected through the switch (not included) and protected by a fuse (not
included) to the DC IN terminal-block connector with correct polarity. The power supply voltage has to
be from 20 - 30Vdc.
