The battery cabinets have ground studs. Use an equipment-grounding conductor to connect the lugs of the cabinets together and to connect the cabinets to the ground bus bar in the UPS module. See
The APC UPS body, its casing, battery cabinet (rack), etc. need to be connected to the electrical grounding device using grounding wires. Generally speaking, the UPS body does not
The battery cabinet must be properly earthed/grounded and due to a high leakage current, the earthing/grounding conductor must be connected first. Failure to follow these instructions will result in
It simply has multiple 5-20R receptacles, each with a ground slot, to which PDUs (power strips for telecom) are connected, to which IT equipment is connected (switches, routers, servers).
Whether the battery system is open-rack or cabinet, the metal rack parts or cabinet must be grounded to the UPS module ground bus. Figure 7 illustrates how a simple, one-cabinet system would be
How does a battery cabinet work? For multiple battery cabinets incorporating battery disconnects, the cabinets are bolted together, forming a single lineup with the UPS. The cabinet grounds are
Connect the DC cables (0W49426) to the DC busbars in the UPS. Route the equipment grounding conductor/PE cable and the DC cables from the rear of the UPS towards the front and up in the gap
In addition to the aforementioned, the UPS''s body needs to be connected to the equipment grounding conductor (EGC) because it is an electrical device in order to maintain equipotential bonding.
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
Connect to the communication port on the UPS and Communication Port 1 on the first battery cabinet. Connect the first string of additional battery cabinet systems.
For a standard substation DC battery rack, I am having trouble determining whether a ground is required to be installed along with the wires between the battery disconnect switch and the
