PREFACE
The CONVEX series underwater lights are
designed to use the latest LED lighting
technology.
The thru-hull designed casings enable very
simple installation on the hull without making
any bigger holes through the hull under water
line.
All the models are available in aluminium
bronze casings. The lighting are available in
white, blue and green colors. All the models
are designed with 6 power LEDs and suitable
power supply units.
FEATURES
Aluminium Bronze Casing
6 Power LEDs Design
White, Blue or Green Lighting
Tempered Glass Optical Window
High-Efficiency Lens
Low Power Consumption
Over-Temperature Protection
Simple Installation
Remote Control (optional)
PRECAUTIONS
The underwater light has to be installed and
used in accordance with the instructions of
this manual only.
The power supply has to be disconnected
before installation.
The underwater light is recomended to be
installed around 0.2 m below the waterline
for the best illumination and to avoid over-
heating.
Do not try to install or remove the
underwater light while the vessel is in the
water.
The optical window has to be cleaned by a
soft brush or cloth. Avoid using any
abrasive or chemical cleaner on the optical
window.
Avoid installing the power supply unit in
extremely hot places and near appliances
generating strong magnetic fields.
Do turn power off immediately and refer
servicing to qualified service personnel if
the underwater light does not operate
normally following the operating
instructions.

INSTALLATION
The underwater light kit consists of the following components:
Underwater Light CONVEX MTH0680
Power Supply Unit MPS02800
Washer
Fixing nut M24
Locking nut M24 with locking screw M8 and bonding screw M4
2 x cable gland M12
Operating Instructions with Declaration of Conformity and Warranty conditions
Underwater Light CONVEX MTH0680
The CONVEX MTH0680 has to be installed on a flat surface on the stern of the hull of the vessel.
Do not try to install the underwater light while the vessel is in the water.
When the installation is finished briefly test the underwater light prior to launching the vessel.
The installation have to be realized by a qualified personnel.

Note:
Avoid using the underwater light out of the water for more than 5 minutes.
The underwater light is protected by a temperature sensor against over-heating. When the
temperature of the underwater light exceeds 60°C the power supply unit starts to reduce
the current of the LEDs. If the temperature of the underwater light exceeds 90°C the
underwater light is automatically switched off.
Hull preparation
The maximum hull thickness can be 90 mm.
The underwater light is recomended to be installed around 0.2 m below the waterline for the best
illumination and to avoid over-heating.
To fix the underwater light the diameter of a hole drilled through the hull has to be 24 mm.
Sealing
Before inserting the underwater light through the hole the sealant has to be used into the grooves
and around the screw M24 in the rear surface of the light and has to be added to the exposed inner
hole surface from the inside of the hull under the washer.
The sealant can be on silicon basis but the best solution is two-component polymer sealant.

7
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 mm2) 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.

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 10 - 30Vdc.
A power supply unit of another underwater light can be connected to the DC OUT terminal-block
connector.
Note:
Only one additional power supply unit of the same model number can be connected to the
DC OUT terminal-block connector and suitable power supply cable should be used. The
appurtenant cap should be removed from the casing and enclosed cable gland M12 should
be inserted.
Underwater light connection
The underwater light has to be connected to the LIGHT terminal-block connector as described in the
table below:

Remote control connection
Remote control (optional) can be connected to the CONTROL terminal-block connector to turn-on
and turn-off and to control the luminosity of the underwater light.
To remotely turn-on and turn-off the underwater light the simple switch (not included) can be used
and connected to the CONTROL terminal-block connector by a 2-pole signal cable (not included).
Note:
To connect the 2-pole signal cable the appurtenant cap should be removed from the casing
and enclosed cable gland M12 should be inserted.
Note:
If remote control is not used for normal operation the both contacts of CONTROL terminal-
block connector has to be bridged.
