TC POINT POSITIONING
The figure below shows the positioning of the maximum temperature point (Tc point, highlighted in red) reached by the electronic board. It is located on the front side (Top) in the centre of the LED module.

INSTALLATION

ATTENTION! Installation and maintenance must always be carried out in the absence of voltage.
Before proceeding with the connection of the device to the power supply, make sure that the voltage of the power source is disconnected from the system.
The device should only be connected and installed by qualified personnel. All applicable regulations, legislation, standards, and building codes must be adhered to. Incorrect installation of the device may cause irreparable damage to the device and connected loads.
The following paragraphs show the diagrams of the LED-module connection to the remote control and the supply voltage. It is recommended to follow these steps to install the product safely:

Remote Control wiring: connect the SPI data bus signals to one of the “DI” terminals (located on the top and left side).
To connect multiple panels in series, connect one of the “DO” output terminals (located on the bottom and right side) to the “DI” terminal of the next module.
Power Supply wiring: connect a 12 Vdc constant voltage SELV power supply to the “V+” and “V-” terminals.

REMOTE CONTROL WIRING
PIXEL-TILE-300-RGBW-12V can be controlled via SPI digital bus. The control is carried out by means of a SPI Master, which provides commands to the devices in the SPI bus.
To connect PIXEL-TILE-300-RGBW-12V to the SPI bus, simply connect the bus cable to the “DI” terminals of the LED module: only serial bus-wiring topology is possible.
SPI WIRING TOPOLOGIES
The SPI protocol supports only the serial Bus-wiring shown as an example in Figure 3.

POWER SUPPLY CONNECTION
PIXEL-TILE-300-RGBW-12V can be powered by either a 12 Vdc constant voltage SELV power supply or a 12 Vdc power supply provided by the SPI Master device, by connecting the power supply to the “V+” and “V-” terminals.
SERIES WIRING
PIXEL-TILE-300-RGBW-12V can be connected in series via the side connectors supplied. The maximum number of modules that can be connected in series depends on the total current draw and the total number of digital LEDs that can be managed by the SPI Master device. To ensure that the product is working properly for series wiring, connect the 12 Vdc power supply (see Figure 4), turn on the power supply, and perform the following checks:
Ensure that the total current absorption on the first module connector in the series is less than 7 A.
Verify that all LEDs are receiving the correct power, checking on the last LED module in the series that the voltage measured on the output connector shown in the figure is within the range (10.8 ÷ 13.2)V.

PARALLEL WIRING
PIXEL-TILE-300-RGBW-12V can be connected in parallel by means side connectors. The maximum number of modules connectable in series depends only to the total number of digital LED that can be managed by the SPI Master device.

TECHNICAL NOTES

INSTALLATION
ATTENTION! Installation and maintenance should always be carried out in the absence of DC voltage.
Before proceeding with the installation, adjustment, and connection of the device to the power supply, make sure that the voltage is disconnected from the system.
The device should only be connected and installed by qualified personnel. All applicable regulations, legislation, standards, and building codes in force in the respective countries must be adhered to. Incorrect installation of the device may cause irreparable damage to the device and connected loads.
Maintenance must only be carried out by qualified personnel in compliance with current regulations.
The product must be installed inside an electrical box that is protected against overvoltage.
The external power supply must be protected. The product must be protected by a properly sized circuit breaker with overcurrent protection.
Keep 230 Vac (LV) circuits and non-SELV circuits separate from SELV safety ultra-low voltage circuits and any product connections. It is strictly forbidden to connect, for any reason, directly or indirectly, the 230 Vac mains voltage to the product (control terminals included).
During installation, it is recommended to reserve adequate space around the device to facilitate its accessibility in case of future maintenance or updates.

Use in thermally harsh environments may limit the output power of the product.
The TA ambient temperature range is a guideline to be carefully observed for the optimal operating environment. However, the integration of the device inside the enclosure must always ensure proper thermal management (e.g. correct mounting of the device, proper ventilation, etc.) so that the temperature at the TC point does not exceed its maximum limit under any circumstances. Proper operation and durability are only guaranteed if the maximum temperature of the TC point is not exceeded under the conditions of use.

POWER AND LOAD
The device must be powered only with SELV power supplies with limited current at constant voltage, short-circuit protection and suitably sized power according to the specifications indicated in the product data sheet. No other types of power supply are permitted. Size the power of the power supply respect to the load connected to the device. If the power supply is oversized compared to the maximum current drawn, insert an overcurrent protection between the power supply and the device.
Connecting to an unsuitable power supply may cause the device to operate outside of the specified design limits, voiding its warranty.
In the case of power supplies equipped with earth terminals, it is mandatory to connect ALL the protection earth points (PE= Protection Earth) to a state-of-the-art and certified earthing system.
The power cables of the device must be correctly sized with reference to the connected load and must be isolated from any wiring or equal to non-SELV voltage. It is recommended not to exceed 10m of connection between the power source and the product. Use doubleinsulated cables.
If you want to use connection cables between the power source and the product longer than 10m, the installer must ensure the correct operation of thesystem.
In any case, the connection between the power supply and the product must not exceed 30m.
Observe the intended polarity between the LED-module and power supply. Any polarity reversal results in no light emission and can often damage the connected LED-modules.
The device has been designed to work with Digital LED-controller only and LED-modules/strip with IC LEDs type specified in the Table 3.
Connecting and powering unsuitable controller and/or LED-module/strip with different IC LEDs type may cause the device to operate outside of the specified design limits, voiding its warranty. In general, the operating conditions of the device should never exceed the specifications indicated in the product data sheet.
Observe the intended polarity between the LED-modules series. Any polarity reversal results in no light emission and can often damage the LED-modules.
The series connection cables between the product, the other LED modules, and the SPI controller must be of an appropriate size and must be isolated from any non-SELV wiring or parts. We recommend using double-insulated cables. The connections between the product, the other LED modules and the SPI controller should not exceed 30m. In any case, the installer must ensure the correct functioning of the system.
It is not allowed to connect different types of LED-modules in the same output channel.

REMOTE CONTROL
The wiring cables at the sync BUS must be isolated from every wiring or parts at voltage not SELV. To improve disturbance immunity at BUS side, the SPI cable should not-cross any 230 Vac mains voltage wiring or radio-emitting sources.
