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.
