3.2.6.3 Connecting AC input power cables
Single Mains
Connect the AC input power cable to mains input power distribution wiring terminals N, 1L1,
1L2, and 1L3.
Mains and bypass input of the delivered UPSs by default share one power source. The neutral
terminals of the mains and the bypass are interconnected internally. No copper bars are required.
The neutral bar is near the cabinet interior. To facilitate cabling, you are advised to connect the
neutral wire before connecting other wires.
