For example, a 40kVA Liebert NX that is scalable to 80kVA should be installed with wiring and breakers rated for an 80kVA configuration. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. Nominal (Nom) current is based on full rated output load at nominal input voltage. Maximum (Max) current is short duration for battery recharge conditions. UPS input cables must be run in separate conduit from output cables. Nominal battery voltage is shown at 2.0 volts/cell per NEC 480-2. 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. Minimum-sized grounding conductors to be per NEC 250-122. Parity-sized ground conductors are recommended. Wiring requirements: AC Input: 3-phase, 3-wire, plus ground AC Output: 3-phase, 3-wire, plus ground All wiring is to be in accordance with national and local electric codes. Minimum access clearance is 3 ft. (0.9m) front and 8 in. (203mm) above the UPS. Top or bottom cable entry through removable access plates. Punch plate to suit conduit size, then replace. Control wiring and power wiring must be run in separate conduit. Dimensions and weights in table do not include external battery cabinet. 80-200kVA UPS dimensions include UPS wiring section for installation without Liebert NX BDC. Deduct 15.5" from UPS width when a Liebert NX BDC will be used. • If site configuration includes a backup 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. • It is 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 an Emerson Network Power sales representative or applications engineer. • The UPS must be fed from a solidly grounded wye or delta AC source. Not for use with impedance-grounded systems, corner-grounded or high leg delta systems. For these applications, an isolation transformer must be installed between the AC feed and the UPS. 2 Site Planning Data - Dual Input, 40-200kVA, 60Hz, 480VAC Site Planning Data - Dual Input, 40-200kVA, 60Hz, 480VAC UPS Rating Voltage kVA kW Input Nom. 40 36 480 AC Input Current Out(A) put Nom.
