However, the integration of the device within the luminaire 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 & 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 wir ing 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 installe r must ensure the correct operation of the system. In any case, the connection between the power supply and the product must not exceed 30m.
The device has been designed to work with LED loads only. Connecting and powering unsuitable loads 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 module and the device. Any polarity reversal results in no light emission and can often damage the LED modules. It is recommended that the connection cables between the product and the LED module be less than 3m long. Cables must be properly sized and should be insulated from any non-SELV wiring or parts. It is recommended to use double-insulated cables. If you want to use connection cables between the product and the LED module longer than 3m, the installer must ensure the correct operation of the system. In any case, the connection between the product and the LED module must not exceed 30m. It is not allowed to connect different types of loads in the same output channel.
LOCAL & SYNC CONTROLS
The length of the connection cables between the local controls (N.O. Push-button, 0-10V, 1-10V, Potentiometer or other) and the product must be less than 10m. For longer lengths (and limited to the N.O. Push-button functionality) it is recommended the use of an N.O. Dry Contact Relay module, connected between the "Input" terminal of the device (dry contact side of the relay) and the power sour ce (coil side of the relay) as shown in the connection example in Figure 4. The cables must be sized correctly. Depending on the connection used, they must be isolated from any wiring or non-SELV voltage parts. It is recommended to use double-insulated and twisted cables, if deemed appropriate, also shielded. All devices and control signals connected to local commands (N.O. buttons or other) must be of the SELV type (the connected devices must be SELV or in any case provide a SELV signal).
