Notes
1.
Nominal (NOM) current is based on full rated output load.
2.
Maximum (MAX) current (125% of NOM) is short duration for battery recharge conditions.
3.
UPS input and bypass cables must be run in separate conduit from output cables.
4.
If the UPS module is to be upgraded in the future, it is recommended that the AC input, bypass AC input, battery, and AC output wiring and overcurrent
protection be sized initially for the future upgraded size.
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 bypass AC input and AC output overcurrent protection represents 125% of nominal full load current (continuous) per NEC 220-2(a).
8.
UPS output load cables must be run in separate conduit from input and bypass 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-16 Note 10.
10. Wiring requirements:
AC INPUT: 3-phase, 3-wire plus ground (unit supplied with input isolation transformer).
3-phase, 4-wire plus ground (unit supplied with input auto transformer).
AC OUTPUT: 3-phase, 4-wire plus ground.
DC INPUT: 2-wire (positive and negative), 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 UPS.
13. Top or bottom cable entry through removable access plates. Cut plate to suit conduit size, then replace.
14. Control wiring and power wiring must be run in separate conduit.
15. Battery cabinet not included.
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 for UPS “on generator” current limit. Consult transfer switch manufacturer for required transfer switch options and sizing.
3.
If site configuration requires an external isolated maintenance bypass circuit, it should be noted that the Utility AC input is not in phase with the UPS AC
output, with the optional delta-wye input isolation transformer. Consult with sales representative or UPS applications engineer.
