Only qualified service personnel (such as a licensed electrician) should perform the electrical
installation. Risk of electrical shock.
The Eaton 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 an Eaton 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 12.
