Electrical Requirements For The Nx Fixed Display - Barco NX-4 Installation Manual

2. Installation requirements
2.4 Electrical requirements for the NX fixed display
Power requirements
One NX control box requires 200-240 VAC, 50-60 Hz, 1.4 amps at 230 VAC. Note that one NX tile correspond with a display surface
of 0.226 m². Each NX tile has a control box. Power split cables are used to link the power from NX control box to NX control box.
However, MAXIMUM eight (8) tiles may be connected in parallel. So, one power source cable has to be provided per eight (8) tiles
. Every power source cable should be protected by a circuit breaker or fuses rated 16 A / 250 VAC (15 A / 250 VAC in the USA and
Canada).
Barco provides a range of power boxes, which meet the requirements of your NX display. Contact Barco for
more information about power boxes and power requirements for your NX display.
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.
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 fixed 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.
