Accessories:

Front Protective Cover: The front protective cover shields the front panel from dust and dirt and water drip. It also prevents the set value from being altered due to accidental contact with tact switches.
Back Protective Cover: Back protective cover (H3PT-MU, C3PT-MU) protects the user tact switches.

Caution:

Do not change the time range & set time while the timer is in operation
Application of voltage other than the specified one, will permanently damage the timer.
Use 2.5mm²U-type lugs with sleeve for connections and wiring .
NOTE : User should not apply external voltage to the terminals that are designated as potential free(Zero/No Volt).
Internal Resettable fuse for protection of device against voltage fluctuations. Digital display will blink whenever the voltage exceeds specified voltage range. Switch off the unit for sometime & then switch on when voltage returns to normal.
