is an intelligent, automatic reclosing protective device designed for single-phase AC 230V systems (rated for 50/60Hz). It serves as a combination of a voltage monitor and an over-current protector, displaying real-time voltage and current on its digital LED screen.
Automatically restores power after the electrical supply stabilizes within safe ranges.

Tighten screw connections firmly. Loose conductor mounting points on single-phase high-amp runs create high contact resistance, inducing heat generation that can damage the internal components.

Check your wiring on the L and N input terminals. If the battery is completely dead (from long storage), it may need to be powered on for a few minutes to charge the internal battery before the screen activates.
