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. Neutral conductors to
be sized for full capacity per NEC 310-15 (b)(4). References are per NEC 1999.
7. Wiring requirements:
a. AC Input: 3-phase, 4-wire, plus ground output.
b. AC Output: 3-phase, 3- or 4-wire, plus ground
8. All wiring is to be in accordance with national and local electric codes.
