For explanation of Applicable Notes, see referenced numbers in Notes below.

REOP = Recommended External Overcurrent Protection

*Dimensions, Weights, and Heat Dissipation for 400, 480, and 600 VAC models

Notes

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

2.Maximum (MAX) current includes the short duration for battery recharge conditions.

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

4.Reserved.

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

6.Power cables from UPS DC link to batteries should be sized for a total maximum 2.0 volt line drop (measured at UPS) at maximum discharge current.

7.Recommended AC output overcurrent protection represents 125% of nominal full load current (continuous) per NEC 220-3(a).

8.UPS output load cables must be run in separate conduit from input cables.

9.Minimum sized grounding conductors to be per NEC 250-95. Parity sized ground conductors are recommended. Neutral conductors to be sized for full capacity per NEC 310-16 Note 10.

10.Wiring requirements:

AC Output: 3-phase, 4-wire plus ground

DC Input: 2-wire (positive and negative) plus ground

Single Source AC Input: 3-phase, 4-wire plus ground Dual Source AC Input:

Converter Input: 3-phase, 3-wire plus ground

Bypass Input: 3-phase, 4-wire plus ground

11.All wiring is to be in accordance with national and local electrical codes.

12.Minimum access clearance is 3 feet front and 1 foot above the UPS.

13.Top or bottom cable entry through removable access plates. Cut plate to suit conduit size, then replace.

Additional Notes

1.If site configuration includes a back-up emergency generator, it is recommended 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.

2.If site configuration includes an automatic transfer switch, refer to the Liebert Power Line titled “Criteria for Application of Automatic Transfer Switches (ATS) with Uninterruptible Power Supply (UPS) Systems” 91K-PLT-48-02. It is also recommended that the transfer switch be equipped with auxiliary contacts. Consult transfer switch manufacturer for required transfer switch options and sizing.
