1.3 Important warnings
Important warnings:
Risk of electric shock:
Do not open. Toreduce the risk ofelectric shock, do not remove cover (or back). Remove all power and data cabling before opening
the device for service purposes. No user-serviceable parts inside. Refer servicing to qualified service personnel.
Maximum and minimum ambient temperature:
The maximum ambient temperature for the LED wall is 45°C, the minimum temperature is -20°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 flammable 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 flow required for safe operation of the equipment is not compromised. Proper ventilation must
be provided.
Risk of electric shock / Risk of fire:
To protect against risk of fire caused by overloading of power cables, MAXIMUM 2 tiles may be connected in parallel. Each power
source cable supplying maximum 2 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 SF-10V tile requires 220-240 VAC, 50-60 Hz, 1.56 amps at 230 VAC.
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 properlygrounded. 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 shouldbe protectedby an appropriately rated disconnect switch, circuitbreakers, over voltageprotector andGround Fault
Current Interrupters. The installation shall be done according to the local electrical installation codes. In Europe special attention
should be given to HD 60364, Harmonization Document 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.
Salty environment
If install in coastal cities, the SF-10V display shall be installed 250 meters away from the shoreline horizontally in dry and cold
climates; 500 meters away from the shoreline in case of high humidity and hot climates. The high humidity and hot climate mean
the climate that the humidity is higher than 80% RH and temperature is higher than 0°C for one third of time every
