5.1 Installing the ProfiLux 4 / 4e
The device must be protected from water at all times!
Mount the controller in a water-protected area. When selecting the mounting material, make
sure that you have adequate sizing and stability. Make sure that the unit cannot fall into the
water during assembly or normal use.
If the device is placed inside an aquarium cabinet, make sure that it is placed in an area free
from splashing water; moisture or liquids that can penetrate.
5.2 Important Operating Instructions
ProfiLux 4 / 4e as well as its accessories (e.g. Powerbar) are destroyed by excess
moisture or too high atmospheric humidity - Please observe the technical data and
notes below!
To ensure safety and safe operation, the following regulations must be followed! In the case
of non-compliance, warranty claims expire, the manufacturer also rejects any responsibility
or liability for damage!
DANGER
•Never leave your aquarium or terrarium unsupervised for an
extended amount of time.
•The ProfiLux can assist you with many tasks and inform you about
error conditions (For example, via email or SMS) - it can in no-way,
replace regular personal supervision and on-site checks-ins.
•The maximum amount of time without personal view depends on
how long your aquarium, terrarium, or pond can survive without
significant damage, even when errors occur.
•Always remember that each technology can fail and 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 ProfiLux 4 / 4e
EN 2019-01-22 17
Powered equipment and water can become a dangerous combination 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!
The Powerbar is operated with mains voltage and is not waterproof. This means that the
socket strip must be protected against moisture and splashing water! Please take note of this
when choosing the installation location.
In order to avoid any danger, all mains-operated devices must be disconnected from the
mains; all plugs must be disconnected! When working in the basin. It can never be ruled out
that a heating element, a pump, or a luminaire is defective.
For safety reasons, the use of a controlled heater is recommended. This should be adjusted
that it switches off slightly above the desired temperature. Thus, the temperature can be
controlled further, but a possible malfunction of the control does not lead to an overheating
of the aquarium.
TIP
•Please ensure good access to the connections of the device
•Please consider the maximum cable lengths of the connected PAB
cables, sensors, Light Bar etc. when selecting the installation site
•Additional sensor cable extensions (BNC2 or VTN cables) and PAB
cables are available in different lengths to fit your needs. They are
available online in our GHL Store (For US customers, GHL USA Store).
WARNING
•To ensure proper operation, the connection cables should never be
kinked, crimped, or positioned in an unsuitable way.
DANGER
On all cables and lines leading out of the aquarium water can run
downwards. Therefore, they must be routed in a way that no water can
enter electrical or electronic parts! This could be accomplished by
arranging so called drip loops at all cables and lines.

Instruction Manual ProfiLux 4 / 4e
EN 2019-01-22 18
5.3 Connecting the Sensors
Connect the sensor connection cables into the corresponding connector sockets provided for
the specific purpose.
TIP
•Place the sensors in an area where water can constantly circulate
around them.
•To prevent algae growth, it is best to place the sensors in a dark
spot. For mounting, an open external filter would be a good place.
•To ensure proper sensor measurement, attach the sensors
perpendicular to the water surface.
•Make sure that the cable connection of the sensor is not immersed
in water under any circumstances.
•Many sensors are very susceptible to interference due to their low
level signals. To provide the most accurate measurements, please
have enough distance between the sensors/cables and sources of
interference. These can include: Electronic ballasts, power lines,
DANGER
Products that are already powered should never be pulled by the cable.
This may cause malfunction or damage the connected products and the
ProfiLux 4 / 4e.
They should only be pulled by the plug connected to the power socket.
ProfiLux 4 / 4e and its accessories are destroyed by moisture or excessive
humidity.
DANGER
•Sensor plugs must not be wet or damp when connecting to the
socket.
•Do not use force.
•Only connect Digital Temperature Sensors from GHL to the
temperature sensor socket of ProfiLux 4 / 4e.
•Always connect the sensors to the respective jacks, as this could
damage the device or the sensors.
•A repair caused by this is not a guarantee and is therefore subject
to a charge.
