Important warnings
Important warnings:
•
Maximum and minimum ambient temperature:
The maximum ambient temperature for the LED wall is 60 °C, the minimum temperature is -20 °C.
•
High leakage current:
The combination of multiple FLX Power System DPR-2700 units and FLX-NNI Controller units in an installation results in in-
creased levels of leakage current. In order to avoid risk of electric shock due to high leakage current, proper grounding of the
installation is required.
•
Flammable materials:
Keep flammable materials away from the installation (such as curtains). A lot of energy is transferred into heat. The installation
should be such that the amount of air flow required for safe operation of the equipment is not compromised. Proper ventilation
must be provided.
•
Disconnect device
A readily accessible disconnect device shall be incorporated in the building installation wiring. See also chapter "Important
warnings for the FLX Power System DPR-2700", page 7.
•
Risk of electric shock / Risk of fire:
To protect against risk of fire by overloading of power cables, MAXIMUM 256 FLX-60 pixels may be connected to one output
port of the FLX-HUB and MAXIMUM 2048 FLX-60 pixels may be connected to one power output socket of the FLX Power
chassis DPR-2700. The FLX Power System DPR-2700 must be connected to the local power net according the manufacturer
specifications and installation instructions delivered with the FLX Power System DPR-2700. If you are unable to install the AC
requirements, contact your electrician. Do not defeat the purpose of the grounding.
•
Non self supporting power/data cables
The FLX-60 Connector strings are not self supporting.
•
Non self retaining pixel socket
Do not rely on the cable socket to guarantee safe mechanical fixation of the FLX-60 Pixel. In other words, do not hang the
FLX-60 Pixel by its cable. To ensure safe installation engage the snap lock or use M3 screws.
Do not rely on the FLX-60 Pixel socket to guarantee safe mechanical fixation of the cable. In other words, do not hang a cable
with a weight of 30N (3kg) or more to one single FLX-60 Pixel.
•
This equipment MUST be earthed:
In order to protect against risk of electric shock, the installation should be properly grounded. Defeating the purpose of the
grounding type plug will expose you to the risk of electric shock.
•
Power system:
It is recommended to use a TN-S power distribution system (a power distribution system with a separate neutral and grounding
conductor) in order to avoid large ground current loops due to voltage differences in the neutral conductor. The total electrical
installation should be protected by an appropriately rated disconnect switch, circuit breakers, over voltage protector and Ground
Fault Current Interrupters. The installation shall be done according to the local electrical installation codes. In Europe special
attention should be given to EN 60364, the standard for electrical installation of buildings. In Germany VDE 0100 should be
adhered to. In America, special attention should be given to the National Electrical Code, ANSI/NFPA 70.
•
Mains cords:
The power cords delivered with this system have special properties for safety. They are not user serviceable. If the power cords
are damaged, replace them only with new ones. Never try to repair a power cord.
•
Data cables:
The data cables provided with this system have special properties for safety. They are not user serviceable. If the data cables
are damaged, replace them only with new ones. Never try to repair a data cable. Avoid exposure of data cables to accidental
contact with lightning or power conductors.
•
IP66 rating:
The FLX-60 pixels, the FLX-HUB units and there connecting wires have an IP66 rating and are therefore totally protected
against dust and against low pressure water jets from any direction. Do not use these FLX products in an environment which
require a better protection rating then the rating it was designed for. The FLX Power System DPR-2700 and the FLX-NNI
Controller units can only be used indoor in a dust free and dry environment.
IP-ratings are defined by the IEC 60529 and this standard also explains in detail how the tests should be performed. This
includes the duration (time) which the equipment shall withstand water without damage or malfunction.
Ingress Protection (IP) rating is identified by a code that consists of the letters IP followed by two digits and an optional letter.

Dust tight
6
Liquids
The FLX-60 pixels, the FLX-HUB units and their connecting wires are designed for outdoor use under a protective roof (or
similar arrangement) that prevents prolonged exposure to rain.
The FLX-60 pixels, the FLX-HUB units and their connecting wires are not designed to be subjected to continuous rain, such as
unprotected outdoor use. This requires a higher protection rating.

No ingress of dust; complete protection against contact
Protected against high pressure water jets from any direction
