Ambient Temperature; Risk Of Fire; Safety For Electricity And Power Supply - NEC FA Series User Manual

Attention!
The installation should be performed only after you are thoroughly familiar with all of the
proper installation instructions and safety checks. This manual contains fundamental
information that should be observed in connection with the installation, start-up, operation and
maintenance of the LED video display. Neglect or not following these instructions will increase
the risk of hazards and injury to the user.
Before work on the system, the power must be disconnected, and the system must be checked
for absence of power and secured against further connection of power.
Clean the unit only with materials or chemicals that are inert, nonabrasive, noncorrosive and
non-marking. Consult the manufacturer for further advice should any doubts exist regarding
any cleaning procedure.

Ambient Temperature

The ambient temperature of the FA 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.

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.

2.4 Safety for Electricity and Power Supply

The electrical systems and their components are not to be opened. The parts inside modules,
which are not user-serviceable, hold high voltages, including when these components are
not in-use for a long time. Accessing these components may lead to serious injury, or property
damage.
Only authorized and qualified personnel may open the system and its components! All
repairs to the system may only be carried out by NEC DISPLAY SOLUTIONS and/or by
respectively authorized and qualified technical personnel.
Power cables and connectors are especially designed to be used indoor according to protection
class IP20. Only use the supplied cables and plugs. The usage of other manufacturers can
cause property damage.
This equipment is designed to be used in the condition of the power cord connected to earth. If
the power cord is not connected to the earth, it may cause electric shock. Make sure the power
cord is earthed properly.
WARNING!
Risk of electric shock and property damage.
Ensure the system is properly grounded.
