Operating Instructions
1.Please connect input (IN), output (OUT), neutral wire (N) and live wire (L) correctly according to the product directive.
2.If the input voltage is normal, NORMAL light on , relay connect. Othersize,the protector displays the fault state and the relay remains disconnected.
3.If the input votlage is greater than over voltage operating value , >U light on.
If the input votlage is lower than under voltage operating value , <U light on.
If fault time is longer than the set delay time , relay disconnect , NORMAL light off , FAULT light on .
4.If over voltage fault protection is on and supply voltage is lower than over voltage reset value , relay will connect and NORMAL light on,
If over voltage fault protection is on and supply voltage is higher than under voltage reset value , relay will connect and NORMAL light on,
5.If supply voltage is lower than 120V, protector activates right away with no action delay , meanwhile , <U light on , and relay will disconnect .
6.To avoid heating of contact from heavy current , please make sure the screwnail on the wiring terminal is tightened so as to prevent protector burning up or other induced disaster .
