2. Operating Advice
Because of the chemical resistance use only a damp cloth for cleaning the light fitting. If necessary
with a mild and solvent-free cleaning agent.
Against penetration of humidity into the light fitting a special explosion-proof breathing gland is often
quite effective. It is allowed to use a breathing gland which is released by the Adolf Schuch GmbH
only. If using a breathing gland please observe the general informations of it's operation
instructions.
Any application of the light fitting that is incorrect or even forbidden will lead to the fact that the
manufacturer's warranty is lost.
Opening the LED compartment is allowed for repair work only.
LED are sensitive electronic components. Please ensure that the LED are protected against
mechanical and electrostatic attacks whenever the light fitting is open. For this reason the LED
must not be touched either.
Due to harmful gases and other corrosive substances (e.g. ammoniac- sulphur-, or chlorine
compounds) it may come to damages of the LEDs. Depending on the substance, the concentration,
the temperature and the dwell time, damages up to total black-out are possible. This may occur
also to fittings with high degree of protection. The suitability of the light fitting for the respective
application can only be checked by running a test at site.
Due to a high inrush current when switching on the light fitting, the number of light fittings which can
be connected to a single fused circuit is limited (Possible number of light fittings per circuit breaker
see Chapter 3, Technical Data).
All DALI dimmable light fittings have two additional terminals marked „DA". Lines to the control
terminals must be mains voltage proof.
LED modules are built up of a series connection, which itself is built up of parallel connections of
single LEDs. Failures of LEDs do not necessarily lead to a change in the power consumption,
which is recognized by the emergency light unit.
2.1 Use at low temperatures
The safety of the light fitting is warranted between -30°C up to +60°C.
At temperatures below 0 °C, it must be taken into account that the emergency battery will take longer
to charge and the operational life of the emergency lighting mode will be reduced. Testing the duration
of the battery life in lower ambient temperatures can therefore lead to a misleading result.
The battery life test should be repeated manually at a more appropriate time (please refer to the
section about operational life testing in Chapter 2.2).
2.2 Automatic test of the emergency light unit
The functionality of the light fitting and the operational life in emergency lighting mode is tested
automatically by the emergency light unit at specified intervals. A blinking green light is emitted by the
signal LED while the test is being carried out.
Functionality test
Functionality tests are carried out at 7 day intervals and last one minute.
The first test of functionality is carried out one hour after the light fitting has been setup. Before this can
happen, it is necessary to separate the emergency light unit built into the light fitting from the mains
power supply before switching on the power, and the emergency battery must have been charged
continuously for one hour.
Operational life test
During the operational life test, the emergency light unit checks whether the capacity of the emergency
battery is sufficient for the indicated nominal operating time should the emergency light being required.
For the operational life test to be carried out, the emergency battery must be fully charged and
connected. For special versions with the option to deactivate the emergency light function, the remote
