Important warnings
Important warnings:
Risk of electric shock:
Do not open. To reduce the risk of electric shock, do not remove cover (or back). No user-serviceable parts inside. Refer servicing
to quali
fi
ed service personnel.
Maximum and minimum ambient temperature:
The maximum ambient temperature for the LED wall is 40 °C, the minimum temperature is 0 °C.
High leakage current:
The combination of multiple tiles in an installation results in increased 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
fl
ammable 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
fl
ow required for safe operation of the equipment is not compromised. Proper ventilation must
be provided.
ESD and LED’s:
LED components used in NX
fi
xed displays are ESD (Electro-Static Discharge) sensitive. To prevent the possibility of destroying
LED components do not touch either in operation or while switched off.
Risk of electric shock / Risk of
fi
re:
To protect against risk of
fi
re caused by overloading of power cables, MAXIMUM eight (8) tiles may be connected in parallel. Each
power source cable supplying maximum eight (8) tiles should be protected by a circuit breaker or fuses rated 16 A / 250 VAC (15 A
/ 250 VAC in the USA and Canada). Note that one NX
fi
xed tile requires 200-240 VAC, 50-60 Hz, 1.4 amps at 230 VAC.
NX control box mounting restriction
Do not mount the NX control box upside down.
Disconnect device:
When the appliance inlets of the individual tiles are not accessible, the socket outlets supplying the rack shall be installed near the
equipment and be easily accessible, or a readily accessible general disconnect device shall be incorporated in the
fi
xed wiring.
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.
LED’s soft lens:
The LED’s used on the NX modules are equipped with a soft lens. Never push with a hard or sharp object onto the soft lens of the
LED as this may cause damage to the LED. The maximum allowed load upon the soft lens of the LED is 300 gram/LED. Be careful
when installing a shader upon the NX module. Use your bare
fi
ngers (not nails) to press the shader over the LED’s. Use your
fi
nger
nails to press upon the framework of the shader between the LED’s (not upon the LED’s) to push the shader in its
fi
nal position.
