Get StartedWithout 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
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.
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 Your UPS is only as reliable as your grounding system.
The wire should have low resistance to ensure effective grounding. The earth wire from the UPS is connected to the building’s main earthing point, such as a grounding rod or earthing busbar. Identify the earthing terminal on the UPS back panel (marked with ⏚ or “Ground”).
The earthing connection in the UPS back panel is a key part of this system. Safety: Protects users from electric shock by providing a low-resistance path for fault currents. Prevents buildup of static electricity. Safeguards the UPS and connected devices from voltage surges, lightning strikes, or short circuits.
Hence such a change-over arrangement practiced between the different raw power sources can not be adopted between the UPS and the bypass supply. That is why the neutral of the raw power should be permanently connected to the neutral of the UPS circuit in order to achieve the integrity of the neutral.
