Appendix A.4.4 Liebert FS Configuration - Single Liebert FS on Series 300 DC Bus

The following Software Control Parameters must be reset when the Liebert FS is connected to the DC

Bus of the Liebert Series 300 UPS system.

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

Initial System Startup.

Appendix A.4.5 Liebert FS Configuration - Multiple Liebert FS Units on Liebert Series 300 DC

Bus

Liebert FS Software Control Parameters must be reset when multiple Liebert FS units are connected

in parallel on the DC bus of a Liebert Series 300 UPS system for proper operation with longer run

times or higher backup power requirements.
Instructions to set these parameters on the Liebert FS are in 6.5.3 - Control Parameters Setup at

Initial System Startup.

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.

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.
