Refer to national and local electrical codes for acceptable external wiring practices.2. Material and labor for external wiring requirements are to be provided by designatedpersonnel.3. For external wiring, use 90° C copper wire. See the appropriate information in Table Ethrough Table G. Wire sizes are based on using the specified breakers.4. Wire ampacities are chosen from Table 310 ---16 of the NEC. Wire is 90°C specification.5. If installing, as part of the UPS system, a maintenance bypass without a rectifier inputbreaker, a minimum of two separate feeds with upstream feeder breakers, or one feed withtwo upstream feeder breakers, must be provided: one for the UPS and one for themaintenance bypass input. DO NOT use one feed or a single-feeder breaker to supplyboth the UPS and the maintenance bypass.
