Appendix A.2.4 Liebert FS Configuration - Single Liebert FS on Liebert Series 610/600T/600 DC Bus

The following Software Control Parameters must be set when the Liebert FS is connected to the DC bus of the Liebert Series 610/600T/600 UPS system.

NOTE

The Software Control Parameter values specified below are recommended. These values may require adjustments due to the battery type. These must be used unless otherwise specified by the Liebert-certified service technician at initial system startup.

Instructions to set these parameters on the Liebert FS are in 6.5.3 - Control Parameters Setup at Initial System Startup.

Appendix A.2.5 Liebert FS Configuration - Multiple Liebert FS Units on Liebert Series 610/600T/600 DC Bus

The Liebert FS Software Control Parameters must be reset when multiple Liebert FS units are con- nected in parallel on the DC bus of a Liebert Series 610/600T/600 UPS system.

Instructions to set these parameters on the Liebert FS are in 6.5.3 - Control Parameters Setup at Initial System Startup.

Multiple Liebert FS Parallel Operation - Regular Configuration with Liebert Series 610/ 600T/600

The Liebert FS Software Control Parameters must be reset when multiple Liebert FS units are con- nected in parallel on the DC bus of a Liebert Series 610/600T/600 UPS system for proper operation with longer run times or higher backup power requirements. The Liebert FS units will contribute all together at the same time to the task of supporting the UPS DC bus.

NOTE

This configuration is recommended for UPS models with output power levels greater than 150 kVA (i.e., 225, 300, 400, 450, 500, 625, 750 and 1,000 kVA).

NOTE

In this configuration, the UPS DC bus usually does NOT have batteries in parallel with the Liebert FS units, however, parallel operation with batteries is acceptable. If batteries to be used are in parallel with the Liebert FS units on the UPS DC bus, contact your local Liebert sales representative to arrange a review of the application.

NOTE

Your Liebert-certified service technician will configure the Software Control Parameter values at initial system startup depending on the number of paralleled units.
