Liebert Series 300 Table 3 Site Planning Data, Series 300 DT, Dual Input 65 to 125 kVA

Installation 9

Notes

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

2. Maximum (MAX) current (125% of NOM) is short dur ation for battery recharge conditions.

3. UPS input and bypass cables must be run in separate con duit 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, an d 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 N EC 480-2.

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

7. Recommended bypass AC input and AC output overcurre nt protection represents 125% of nominal full load current (co ntinuous) per NEC 220-2(a).

8. UPS output load cables must be run in separate cond uit from input and bypass cables.

9. Minimum sized grounding conductors to be per NEC 250 -95. Parity sized ground conductors are recommended. Neutra l 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 tr ansformer).

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 p late to suit conduit size, then replace.

14. Control wiring and power wiring must be run in separate cond uit.

15. Battery cabinet not included.

Additional Notes

1. If site configuration includes a back-up emergency generator, it is recomm ended that the engine generator set be properly sized and equipped for a UPS

application. Generator options would typically include an iso chronous governor (generator frequency regulation) and a UPS compatible regulator

(generator voltage regulation). Consult generator manufac turer for required generator options and sizing.

2. If site configuration includes an automatic transfer sw itch, refer to the Liebert Power Line titled “Criteria for Appl ication 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 trans fer 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 transform er. Consult with sales representative or UPS applications engin eer.
