    Hints on correct use:

    • Use proper gauge wires for connections.
    • Ensure all terminals are tightly screwed.

    Caution:

    • If the input voltage shoots beyond the specified range, the unit will be damaged beyond repairs. Suitable protection for incoming voltage is recommended.
    • Use 2.5mm 2 U-type lugs with sleeve for wiring and connections.
    • If the source voltage shoots beyond the rated voltage, the units will be damaged beyond repairs.
    • EAPL does not take responsibility for any consequential damages.
    • NOTE : User should not apply external voltage to the terminals that are designated as potential free(Zero/No Volt).
