LECTRICAL
The Powerware 9170 UPS input power may be hardwired through
conduit to either a main power source circuit breaker or to an optional
external bypass switch. For hardwired installations, it is recommended
that you install a Powerware bypass switch to enable power transfer
during maintenance or UPS downtime. If a bypass switch is used, both
UPS input and UPS output must be hardwired– through separate
conduits –to the bypass switch, as shown in Figure 18.
