Instruction Manual Mitras LX7
EN 2016-12-27 7
WARNING
Maintenance and cleaning for the luminaire should only be
performed when the unit is powered down. The luminaire must be
suspended from the ceiling fixture or disconnected from other
mounting kits. Make sure to unplug the power cord first.
Be careful when touching the lamp during operation. Some parts of
the lamp can get very warm.
The LEDs of the luminaire are extremely bright. Do not look directly
into the light source.
The luminaire must be regularly cleaned. To do this, it must be
switched of.
Disconnect the power plug by pulling the plug, not the cable.
Never attempt to disassemble, repair or alter the equipment by
yourself.
Do not insert sharp objects into the electrical contacts and ports.
DANGER
If the unit falls into the aquarium or has been exposed to moisture
or humidity, first turn off the power to the device via the fuse or
circuit breaker, then pull the power cord.
Never touch the power plug with wet hands.
If the contact of the plug is wet or soiled, please dry it completely or
clean it with a cloth. The mains plug must not be immersed in the
water.
DANGER
The device may not be operated if it has been damaged in any way
(e.g. damaged power cord or plug, liquids or objects have gotten into
the interior, device has been exposed to excessive moisture, the
normal operation is disturbed, or the device has been dropped).
If the plug or socket gets wet, first turn off the power to the device
via the fuse or the circuit breaker. Then pull the power cord.
If the lamp has fallen into your aquarium, first pull the mains plug
before you pull it out of the water. Under no circumstances should
the lamp be used again!
Never operate the lamps then leave it unsupervised when children,
pets or persons are nearby.
When cleaning the aquarium, pull the mains plug of the luminaire.

Instruction Manual Mitras LX7

5Activation
5.1 Installing the Mitras LX7
This device must be protected from water at all times!
The Mitras LX7 can be positioned above the aquarium by using the Mitras Flex Mount System
or Mitras Hanging Kit. Please make sure to allow sufficient space between the fixture and top
of the aquarium. When selecting the mounting material, make sure you have adequate sizing
and stability, and make sure that the unit cannot fall into the water during assembly.
Mitras LX7 can be destroyed by excess moisture or atmospheric humidity - please
observe the technical data and notes below!
To ensure safe operation, the following guidelines must be followed! In the case of non-
compliance, warranty claims expire, the manufacturer also rejects any responsibility or
liability for damage!
Powered equipment and water can become a dangerous combo if precautions are not taken.
It is therefore essential to supply power to all mains-operated devices which are operated in
the aquarium or in the vicinity of the device via a residual current circuit breaker!
In order to avoid any danger, all mains-operated devices must be disconnected from the
mains; all plugs must be disconnected!
DANGER
The luminaire is to be used exclusively for illuminating open aquariums in
dry indoor areas.
The luminaire must not be operated under a closed aquarium cover
or canopy. Excessive humidity and high temperatures will damage
the luminaire (See technical data)
The luminaire must be mounted at least 20 cm (7.87”) away from the
top of the aquarium.
The lamp must not be operated lying on the edges of the aquarium.
To avoid heat build-up, the luminaire must not be operated in a
horizontal position. A minimum distance of 10 cm (eg to a splash
screen) must be maintained under the protective screen of the

Instruction Manual Mitras LX7
EN 2016-12-27 11
Minimum distance to the upper edge of the aquarium:
luminaire.
Under no circumstances should the luminaire be operated without
the protective shield or with a damaged shield.
The luminaire must be protected against splashing water, excess and
condensing humidity. Please observe the following technical data.

Instruction Manual Mitras LX7
EN 2016-12-27 12
TIP
The Mitras LX7 is equipped with an acclimation program that allows you to
easily adjust the performance and output of the light.
WARNING
To ensure proper operation, the connection cables should never be
kinked, crimped, or positioned in an unsuitable way.
5.2 Connection to the Power Supply / Switching on the Mitras LX7
Connect the luminaire power cable to the power supply. Connect the power supply unit to
the power cord and connect the power connection cable with the plug to the power outlet.
DANGER
Aquarium specimens are very sensitive to sudden changes in lighting
conditions. If an adjustment (duration, intensity, color and alignment of the
lighting) is needed, please perform these changes gradually and observe
the reaction of the ecosystem in the aquarium.
DANGER
Products that are already powered should never be pulled by the cable.
This may cause malfunction or damage the connected power supply and
the Mitras LX7.
They should only be pulled by the plug connected to the power socket.
Mitras LX7 and its accessories are destroyed by moisture or excessive
humidity.
DANGER
Ensure that the mains voltage matches the voltage specified on the
identification plate located on the bottom of the device.
Connect the device only to a properly installed and grounded outlet
with a minimum rating of 10A.
Never use a different voltage supply. Incorrect polarity or voltage can
destroy the device.

Instruction Manual Mitras LX7
EN 2016-12-27 13
6Operation
6.1 Operation on the Device
Use the navigation buttons (arrow keys) on the device to make settings or desired changes to
your settings.
The Mitras LX7 can be operated as a stand-alone light or together with several lamps in the
master and slave mode.
Use only the supplied AC adapter
DANGER
Never leave your aquarium unsupervised for an extended amount of
time.
Always remember that technologies can fail and therefore,
malfunctions can never be ruled out!
Power failures, incorrect settings, damage (For example, by water or
overvoltage) or simply an unexpected operating situation can lead to
fatal damage.
The manufacturer disclaims any liability for (consequential) damages
or losses which might arise in connection with the use of the ProfiLux
System extent legally permissible.

Instruction Manual Mitras LX7
EN 2016-12-27 14
TIP
Master and Slave modes are ideal for running simulations across all
luminaires. These simulations can be performed across one or more
luminaire:
Gliding cloud simulation
Sunrise and sunset with east-west simulation
Thunderstorm
It is particularly convenient to use these settings via the GHL Control Center
(See below 6.2)
Set the time and date first.
TIP
If several Mitras® LX7 are operated, it is sufficient to make the settings for
the lighting and the clock with only one luminaire.
Set this luminaire as a master (Menu: System-> Wireless), the others as
slaves, and give the luminaires different addresses (Nos.1-31).
The settings of the master light are then transmitted via radio to the other
luminaires.
Press any arrow key to enter. You can move up and down from the right to the left with the
arrow keys in the menu. The right and left arrow keys are programmed as shortcut keys. You
can press the buttons to go directly to thunderstorm or maintenance.
The operation of the device is very simple. Use the up and down arrow keys to navigate
through the menus and make a selection.
To confirm the selection of a menu item, press the confirmation key (Check mark button:
Confirm input = Return). This will take you to the sub-menus.
Make the desired changes and save them with the confirmation key. Press the Cancel key
(Cross mark button: Cancel input = Escape) to abort entries.
After each setting process, you are asked if you want to save the changed settings. Only after
confirmation with Yes, the new settings are accepted and saved. These settings are also
stored in the nonvolatile memory (EEPROM, independent of the mains voltage) and are
restored after voltage interruption.
