The frame of the UPS should be connected to the neutral of the UPS and then to a nearby earth electrode in order to create an effective TNS earthing system at the UPS itself for avoiding neutral to
This manual contains important instructions that should be followed during installation and maintenance of the UPS and batteries. Read all instructions before operating the equipment and save this manual
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
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
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
All exposed conductive parts of the installation must be connected to the earthed point of the power system by protective conductors which must be earthed at or near to each relevant transformer or
When batteries are not installed in a cabinet, i.e. generally in a special room, the measures presented at the end of this chapter should be implemented. Note: The TN system
