2.4 Typical Applications

The PCS100 UPS-I may be applied to provide protection in low voltage systems. The following diagrams show
typical applications providing protection to an entire factory and sensitive electronic loads within that factory.
CAUTION
The PCS100 UPS-I is designed for use in TN power systems. For any other type of power
distribution system please refer to ABB document 2UCD120000E017, or contact the ABB factory for
information. See Figure 19-1 for typical connection details.
Figure 2-8 shows a typical PCS100 UPS-I installation where the PCS100 UPS-I is used to protect the complete
factory. The PCS100 UPS-I is installed between the incoming breaker and the factory LV distribution system.

Figure 2-9 shows typical PCS100 UPS-I installation where the PCS100 UPS-I is used to protect a specific load. The
PCS100 UPS-I is installed within the LV distribution system, i.e. on the feeder supplying the specific load to be
protected.

ABB recommends that a maintenance bypass (not supplied with the PCS100 UPS-I) is fitted. The maintenance
bypass allows maintenance to be performed on the PCS100 UPS-I without disruption to the load.
