warranty. However, when wired with the optional isolation transformer, input neutral is supplied by the
isolation transformer.

* Use only 75°C-rated copper wire. Minimum wire size is based on 120/208 full load ratings applied to
NEC Code Table 310-16. 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 requirements.
8. Connect the factory-installed wiring from the maintenance bypass switch to the
UPS terminal block (see Figure 20).
Connect the maintenance bypass (red and black) wires to TB1-2 (the A/B
maintenance bypass auxiliary contacts) on the UPS terminal block.
