Notes for Table
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.
Power cables from UPS DC link to batteries should be sized for a total maximum 2.0V line
drop (measured at the UPS) at maximum discharge current.
6.
OCPD=Overcurrent Protection Device. Recommended AC input and AC output overcurrent
protection represents 125% of nominal full load current (continuous) per NEC 215.
7.
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.
8.
Wiring requirements:
AC Input and Output: 3-phase, 3- or-4-wire plus ground, depending on UPS configuration.
See Installation Manual and submittal drawings for specific instructions.
DC Input: 2-wire (positive and negative), plus ground.
9.
All wiring is to be in accordance with national and local electrical codes.
10. Minimum access clearance is 3 ft. (0.9m) front and 1 ft. (0.3m) above UPS.
11. Top or bottom cable entry through removable access plates. Punch plate to suit conduit
size, then replace.
12. Control wiring and power wiring must be run in separate conduit.
13. Weights and dimensions shown do not include battery cabinet, Slim-Line distribution
cabinet or other options.
14. Add 560 lb. (254kg) for 100-130kVA unit with dual input and isolated 208VAC output.
15. Backup emergency generator must be properly sized and equipped with an isochronous
governor (generator frequency regulation) and a UPS-compatible voltage regulator.
16. An on-site automatic transfer switch should be equipped with auxiliary contacts for UPS
“on generator” current limit. Refer to Liebert publication 91K-PLT-48-02.
17. An external isolated maintenance bypass circuit might cause utility AC input to be out of
phase with the UPS AC output.
