It also prevents the set value from being altered due to accidental contact with time setting knob Hints On Correct Use Change the positions of range selector slide switches on the left hand side of the timer to set the range required & then rotate the pot to set the desired time setting with the flat blade screw driver. Caution ● ● ● ● ● Do not change the time range & set time while the timer is in operation. Switch off the power while changing the time range & set time. Application of voltage other than the specified one, will permanently damage the timer. Use 2.5mm2 U-type lugs with sleeve for connections and wiring. NOTE: User should not apply any external voltage to the terminals that are designated as potential free(Zero/No Volt).
