A UPS in standard configuration has only one switch cable (maintenance bypass switch). A UPS in full configuration has three switch cables (mains input switch, maintenance bypass switch, and bypass input switch). The following figure shows how to connect cables to a parallel system in full configuration.
Connecting Cables 1. This document describes cable routing by removing the top cover when there are two mains inputs. 2. In the case of single mains, you do not need to connect bypass input power cables and remove short-circuit copper bars. UPS Cable Connection Reference •...
