Notes for Table
1. Recharge current shown is the maximum the Liebert FS can accept. This
value is dependent on the UPS, typically limited to 15% of the UPS’s nominal
full load DC current.
2. Recharge voltage is adjustable, 480 to 500VDC. 190kW requires >520VDC.
3. Discharge voltage is adjustable, 480 to 500VDC. 190kW requires >510VDC.
4. Discharge rates below 190kW increase the discharge duration time (see
Figure 1). In addition, the FS has the capability to discharge at rates above
190kW for shorter discharge durations. Please consult factory for details.
5. Power cable from UPS DC bus to Liebert FS should be sized for total
maximum 2.0 volt line drop (power cable plus return cable drop as measured
at the module) at maximum discharge current.
6. Grounding conductors to be sized per NEC 250-95.
7. All wiring to be in accordance with National and Local Electrical Codes.
8. Minimum clearance is 3 ft. (0.9m) in front and 1 ft. (0.3m) above the
Liebert FS.
9. Exterior cable entry available through removable top access plates: remove,
punch to suit conduit size and replace.
10. Control wiring and power wiring must be run in separate conduit.
11. When used with the Liebert Series 300, nominal recharge voltage is
395VDC, nominal discharge voltage is 385VDC, with adjustable range of 360
to 405VDC for both. Due to lower VDC, power output below 30 seconds must
be derated. Contact factory for details.
12. AC auxiliary power input required: 110/230VAC, 1 ph, 400VA.
Additional Notes
• If site configuration includes a backup emergency generator, it is recom-
mended that the engine generator is set to be properly sized and equipped for a
UPS application. Generator options would typically include an isosynchronous
governor (generator frequency regulation) and a UPS-compatible regulator
(generator voltage regulation). Consult the generator manufacturer for
required generator options and sizing.
