Review the installation wiring diagram and applicable notes to find the proper circuit breaker size for your installation. In the US, see Table 10 to size the wire. In other areas, use 75°C copper wire and size according to the local code.

Table 10. Recommended Wire Sizes

This table lists the AWG and mm2 wire size for each circuit breaker size shown on the wiring diagrams. The minimum recommended circuit breaker sizes for each model and voltage application are listed on the wiring diagrams.

Conductor sizes shall be no smaller than the 75°C wire size based on the ampacities given in Table 310–16 of the National Electrical Code, ANSI/NFPA 70-1999, and article 220. All circuit conductors, including the neutral and equipment grounding conductors, must be the same size (ampacity) wire. Code may require a larger AWG size than shown in this table because of temperature, number of conductors in the conduit, or long service runs. Follow local code requirements.

Mount the bypass switch within sight of the UPS. If you do not have a Powerware bypass switch with an AC disconnect switch or the fuse box or panel is out of sight, you must install a separate disconnect switch next to the UPS.

Remove the screws in the lower part of the bypass switch front cover and remove the lower cover panel.

Remove the knockouts or plugs in the bottom of the bypass switch for AC Line Input, AC to UPS Input, AC from UPS Output, and AC to the UPS load.
