Safety For Electricity And Power Supply - NEC LED-FA031i2 Safety Manual

1.5 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 Sharp 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.
Caution!
Risk of overload of the power cable.
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.
The limit values specified in the technical data must never be exceeded.
•
Only operate the system with supplied accessories (cables, power distribution, assist grip,
•
transport carts). However, a power cord to supply power is not included.
Do not operate or touch the system with wet hands.
•
• Use the provided transition ramps (cable channels). Protect the cable against kinks and
sharp edges.
Notice
Use a TN-S power distribution system with a separate neutral and grounding conductor. Due
to voltage differences in the neutral conductor, large ground current loops can be avoided
therewith.
The complete electrical system should be protected by an appropriately rated disconnect
switch, circuit breakers, over voltage protector and Ground Fault Current Interrupters.
The power system needs to be installed according to the local electrical installation codes. For
Europe, installations have to be conform to DIN-EN 60364 – the standard for electrical
installation of buildings, (and related harmonized Norms). In Germany, the VDE 0100 should
be followed and adhered to.
