2.3.1

Ambient Temperature

The ambient temperature of the FE Series is maximum +40°C and minimum -20°C.
To avoid damage of the LED wall by over-heating, do not exceed the ambient temperature.
2.3.2

Risk of Fire

Keep flammable materials away from the installation. During operation a lot of energy is
transferred into heat. The installation should be placed so that the amount of air flow required for
safe operation of the equipment is not compromised.
Proper ventilation must be provided. Never block the air ventilation holes. Keep them free at all
times.
To protect the power cable against overload maximum 10 cabinets shall be wired in a row at
100 V AC or 20 modules at 240 V AC. The total load must not exceed 16 A per cable.
To avoid risk of fire due to overheating of the cables, only use the supplied cables that are meant
for the system and its components. Damaged cables must be replaced by new cables. The cables
are not user serviceable.
