Fixing
The underwater light has to be inserted through the hole from outside of the hull and has to be fixed
with the fixing nut M24. Then the locking nut M24 (with locking screw M8 and bonding screw M4) has
to be fitted and locked with locking screw M8.
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 nuts and screws 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
locking nut M24.
Note:
It is highly recommended to paint the entire underwater casing exposed to the water with
anti-foul paint.
The optical window is protected with foil which has to be removed after anti-fouling
process.
Power Supply Unit MPS02800
The MPS06800 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.
