Notes for Table

1.Nominal (Nom) current is based on full rated output load at nominal input voltage.

2.Maximum (Max) current (140% of nominal) is short duration for battery recharge conditions and low input voltage.

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.For Single Input units only.

For Dual Input units, see “Electrical Data Specification Sheet, 40-120kVA UPS Module, Single or Dual Input Liebert NX - U3819100.”

6.OCPD = Overcurrent Protection Device. Recommended AC input and AC output overcurrent protection represents 125% of nominal full load current (continuous) plus 100% of recharge current (non-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: 3-phase, 3-wire, plus ground

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

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

10.Minimum access clearance is 3 ft. (0.9m) front and 8 in. (203mm) above the UPS.

Notes for Table (continued)

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.Dimensions and weights in table do not include external battery cabinet.

Additional Notes

•Input and output wiring and breakers for a Liebert NX with Softscale technol- ogy should be sized for the maximum scalable capacity. For example, a 40kVA Liebert NX that is scalable to 80kVA should be installed with wiring and breakers rated for an 80kVA configuration.

•If site configuration includes a backup emergency generator, it is recom- mended that the engine generator set be properly sized and equipped for a UPS application. Generator options would typically include an isochronous governor (generator frequency regulation) and a UPS-compatible regulator (generator voltage regulation). Consult generator manufacturer for required generator options and sizing.

•If site configuration includes an automatic transfer switch, refer to Liebert Power Line titled “Criteria for Application of Automatic Transfer Switches (ATS) With Uninterruptible Power Supply (UPS) Systems,” publication

91K-PLT-48-02. It is also recommended that the transfer switch be equipped with auxiliary contacts for UPS “on generator” current limit. Consult transfer switch manufacturer for required transfer switch options and sizing.

•If site configuration requires an external isolated maintenance bypass circuit, it should be noted that utility AC input might not be in phase with the UPS AC output. Consult a Liebert sales representative or applications engineer.
