1.Nominal (Nom) current is based on full rated output load.

2.Maximum (Max) current (125% of nominal) is short duration for battery recharge conditions.

3.UPS input and bypass cables must be run in separate conduit from output cables.

4.Nominal battery voltage is shown at 2.0 volts/cell per NEC 480-2.

5.OCPD = Overcurrent Protection Device. Recommended AC input and AC output overcurrent protection represents 125% of nominal full load current (continuous) per NEC 215.

6.Minimum-sized grounding conductors to be per NEC 250-122. Parity-sized ground conductors are recommended. References are per NEC 1999.

7.Wiring requirements:

a.AC Input: 3-phase, 3-wire, plus ground.

b.AC Output: 3-phase, 3-wire, plus ground.

8.All wiring is to be in accordance with national and local electric codes.
