6 Frequently Asked Questions about “UPS battery cabinet connected to ground bar”
How do I connect a cabinet ground bus?
The cabinet grounds are inherently connected to the UPS ground bus via the metal chassis. You must connect the supporting racks of a wet-cell installation to the battery disconnect and to the UPS module ground bus. You should connect the racks directly to the local UPS room ground bus only if required by local electrical codes.
How does a battery ground fault affect an ups?
The same condition will exist in a UPS system with a (single) battery ground fault. The unit will continue to run, but a battery ground leakage detection monitor will sense the ground current, and then can trigger an alarm on the monitor, and/or through a “building alarm” in the UPS.
How do you connect ups to a ground bus?
Bond the neutral of the UPS output to the local UPS room ground bus. Some UPS modules come equipped with an input isolation transformer, but these don't influence whether you deem the system to be a separately derived source.
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
How do you connect a neutral bus to a grounding point?
But you must bond the neutral bus and ground bus in the system cabinet together and connect them to the local grounding point. Typically, the grounding point is a copper bar mounted on insulators in the electrical room and bonded to the local building steelwork.
What is a grounding point for a UPS system?
Typically, the grounding point is a copper bar mounted on insulators in the electrical room and bonded to the local building steelwork. Whenever you use a delta-connected supply for a UPS system, you must create an artificial neutral. In such cases, a three-resistor network typically provides a logic reference point for the bypass input.
