PVE 1000 D / PVE 1001 D: 1000W Relay Type AVR w/ Power on Delay, Output 220V AC

Hello, Thank you for your inquiry. Regarding your question about the grounding of the AVR: As mentioned, all of our AVRs are designed with case grounding, and appliances plugged into the 3-prong outlet are internally connected to the grounding terminal of the AVR. However, if there is a current leak from an appliance and it causes the metal casing to become energized, the leak will typically travel through the AVR’s case grounding. To ensure safe dispersal of the current, we recommend adding a grounding wire from the screw near the power cord of the AVR to a grounding rod. This will direct any stray current safely to the ground, preventing it from traveling through the metal casing of the AVR and minimizing the risk of electric shock. Please ensure that this grounding modification is done by a qualified technician to ensure safety and compliance with local electrical standards. Let us know if you have any further questions or need assistance!
