Operation Instruction:

  1.Wire the protector according to the indicator IN and OUT directive.

  2.When the protector is with normal supply voltage, yellow R/T indicator stays light-on, relay implements output action; otherwise protector showsfault while relay gets disconnected.

  3.In case supply voltage goes over the set voltage operating value, yellow R/Tindicator flickers and red U > indicator light-on. When fault time islonger than the set delay time, output relay gets disconnected, R/T indicator light-off.And if supply voltage is lower than undervoltage operating value, yellow R/Tindicator flickers and red U< light-on. Also when fault time is longer than the set delay time, output relay gets disconnected, R/T indicator light-off.

  4.When overvoltage fault protection is on and supply voltage is lower than overvoltage reset value, output relay actuates and R/T indicator light-on;when overvoltage fault protection is on and supply voltage ishigher thanundervoltage reset value, output relay actuates and R/T indicator light-on.

  5.When supply voltage is lower than 150V, protector activates right away with no action delay;meanwhile,yellow R/T indicator light-off, red U< indicator  light-on,and output relay gets disconnected.

  6.Wiring terminal: N represents Neutral Line, L represents Live Line, please donot mix up.

  7.To avoid heating of contact from heavy current, please make sure the screw nail on the wiring terminal is tightened so as to prevent protector burning-up or other induced disaster.
