Matters needing attention
1. install this product in indoor or outdoor waterproof case box, avoid direct rain, sun.
2. when installing this product, it is best to cooperate with the air switch to ensure the safety of the electrical equipment.
3. if the product is energized after 3-5s, four failure indicator in bright red, shows that the power line or equipment with the corresponding fault, should be timely check and eliminate the fault line.
4. installation must be done according to the polarity mark on the panel of the product, especially the input and output can not be connected.
Over-current, short-circuit or leakage protection action disconnect 30s automatic reclosing after the first 1 times, such as troubleshooting is successfully closed, such as fault has not ruled out is not closing, delay 15min second reclosing, if not successful closing again for the third time delay 15min reclosing, if not successful, is prohibited then reclosing; overvoltage, undervoltage protection action disconnect 30s, first determine the fault has been ruled out, such as closing, such as fault has not ruled out is not closing, two times and three times of closing and closing no switching time and current protection of the same discrimination. Successful closing means that 5S can not be tripped after closing action.
Operation and use
1. installation: this protector can guide rail type installation, can also be equipped with waterproof box after outdoor pole installation; outdoor pole installation, fixed on the pole, pay attention to the protection of the outlet end is connected to the load down, protector of the outlet end; check on the power supply line switch, then the products. The switch is in the ON, output indicator lights, automatic switch on the output power, said power supply is normal.
2. leakage protection: press the test button, or equipment 30mA leakage, the product immediately disconnect the output line, indicating leakage protection function is normal, at this time "leakage" indicator light red light. This product will be the first automatic reclosing in 30s, if the leakage fault persists, and immediately after the closing of the trip into the second 15min after reclosing, such as leakage phenomenon still exists, and immediately after the closing of the trip, 15min third times after reclosing, after three times after closing, if the fault is still there is, this product into the self-locking state, no longer reclosing, need to manually cut off the power supply or remote reset (this product overlap interval in full accordance with the national standard setting, such as a special case, can be modified according to customer requirements), troubleshooting, and re energized, in order to re reclosing. Remark: no fault occurs in the 5S after closing, and the switch is successful and the number of failures is automatically cleared.
3.: if the power supply voltage and overvoltage protection in 270 + 10V, this product enters an overvoltage protection state, tripping cut off electricity, "overpressure" corresponding fault indicator light red light, 30s back to normal voltage switch, otherwise keep overvoltage state until the voltage is normal only after closing, if the voltage is not normal is not closing the action of judgment, but if not more than 5S after closing and opening, will have to wait for 15min to determine whether the normal voltage.
4. undervoltage protection: if the power supply voltage in the 154 + 10V, this product enters the undervoltage protection, cuts off the power supply, the corresponding "undervoltage fault" indicator light red, 30s voltage restore normal closing, or remain under pressure until the off state voltage normal only after closing, if the voltage is not normal not to carry out the closing action to judge, but if not more than 5S after closing and opening, will have to wait for 15min to determine whether the normal voltage.
5. overcurrent protection: if the current exceeds 1.15In, the products to enter the state of overload protection, cuts off the power supply, the corresponding "over current / short circuit fault indicator light red, on judge 30s, if still overload, 2-5s gate, and then to 15min again on judgment, only the current recovery and closing more than 5S, it is on.
6. short circuit protection: if the current exceeds 3In, the short circuit protection products to enter the state, cuts off the power supply, the corresponding "over current / short circuit fault indicator light red, on judge 30s, if still short circuit, 0.1s gate, and then to 15min and then closing judgment, only the current recovery and closing more than 5S, it is on.
