supply. road lamp, please b e h r lamp power assured to use t e oad 3) Before connecting the product with any load, please disconnect the input wire and be assured the load is matching; never connect the input and the output wire reversely; if the pro-duct has the grounding wire, please connect it with the ground correctly; 4) Never apply overload (exceeding the rated power) or sup ( for instance a-erlight loadpply 1w onto the 100W constant voltage power; or the constant current product is under the minimal output voltage of the power ) onto the power supply; otherwise it may cause the LED light flashing; 5) Lightning protection and filtering: When using the product outdoor or on high buildi-ng, please provide the lightning arrester; if the electric grid fluctuates seriously or the ambientenvironment is rather worse, p us the surge absorption plant; lease e 6) If the neutral wire is broken: the neutral wire of the 3- system plays the phase 4- wirerole of protecting the zero potential of the neutral point if there is unbalanced current flowing the 3-phase load and making the voltage of very phase unchanged. If the neutral wire is brok-en, the voltage of the phase with the lowest load shall rise and cause damage. Certainly the neutral wire of the 3-ph ase 4 - wire system must be kept in good condition without interrupti-on, with relative larger cross-section additionally (it is not limited by this clause if the PFC po-wer supply is available). 7) If the load connected with the power is the capacitive load, it may possibly not be started since the instantaneous starting current is too larg can trigger the automatic e ( which protection to the power supply ), so the power can not be used directly; if it is needed to use, please add the compensation device at the load to weaken or relieve the impact. 8) If the same project uses plenty of LED s witching power supplies, is needed it to pow-
on step by step; otherwise the one-switch start may cause large impact c urrent and trig-erger electric trip.

7. Warning and disclaimer 1) The product must only be connected and changed by the personnel with -the professional qualifications; 2) Never use the regular products to drive the LE road lamps; if it is a must to drive the D
supply. road lamp, please b e h r lamp power assured to use t e oad 3) Before connecting the product with any load, please disconnect the input wire and be assured the load is matching; never connect the input and the output wire reversely; if the pro-duct has the grounding wire, please connect it with the ground correctly; 4) Never apply overload (exceeding the rated power) or sup ( for instance a-erlight loadpply 1w onto the 100W constant voltage power; or the constant current product is under the minimal output voltage of the power ) onto the power supply; otherwise it may cause the LED light flashing; 5) Lightning protection and filtering: When using the product outdoor or on high buildi-ng, please provide the lightning arrester; if the electric grid fluctuates seriously or the ambientenvironment is rather worse, p us the surge absorption plant; lease e 6) If the neutral wire is broken: the neutral wire of the 3- system plays the phase 4- wirerole of protecting the zero potential of the neutral point if there is unbalanced current flowing the 3-phase load and making the voltage of very phase unchanged. If the neutral wire is brok-en, the voltage of the phase with the lowest load shall rise and cause damage. Certainly the neutral wire of the 3-ph ase 4 - wire system must be kept in good condition without interrupti-on, with relative larger cross-section additionally (it is not limited by this clause if the PFC po-wer supply is available). 7) If the load connected with the power is the capacitive load, it may possibly not be started since the instantaneous starting current is too larg can trigger the automatic e ( which protection to the power supply ), so the power can not be used directly; if it is needed to use, please add the compensation device at the load to weaken or relieve the impact. 8) If the same project uses plenty of LED s witching power supplies, is needed it to pow-
on step by step; otherwise the one-switch start may cause large impact c urrent and trig-erger electric trip.
