Does my ups need a grounding system?
Without a properly installed grounding system, your UPS won't function correctly. A grounding system allows circuit protection to clear a ground fault, and provides paths for diverting surge current away from the UPS and for removing undesirable currents from the critical load. So what can you do to ensure your grounding system allows your UPS
What is grounding in a ups?
Earthing (or grounding) is a critical safety feature in Uninterruptible Power Supply (UPS) systems. It ensures the safe operation of the UPS and connected devices by providing a path for fault currents to dissipate into the ground, preventing electric shock, equipment damage, and fire hazards.
