1303 Installation Overview
The Axxium Pro UPS may be installed with the input (mains) connection hard wired through conduit to either a
supply (mains) circuit breaker or an optional external bypass switch. If a bypass switch is used, both UPS input
and UPS output must be hard wired–through separate conduits–to the bypass switch, as shown in Figure 14.
If a bypass switch is not used, the UPS input may be hard wired (through conduit) to a mains circuit breaker,
and the UPS output may either be hard wired to a circuit breaker in a distribution panel (as shown in Figure 15)
or supplied to loads through receptacles on the back of the UPS. Without a bypass switch, power to the load
cannot be maintained if the UPS is taken completely offline.
The UPS input (mains) connection may also be made through a power cord plugged into a mains receptacle. In
such an installation, the UPS must be installed near the mains (input power) receptacle and the plug must be
readily accessible. In this case, the UPS output must be supplied through receptacles on the back of the UPS.
