Appendix A.3.5 Liebert FS Configuration - Multiple Liebert FS Units on Liebert Npower 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 Npower 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
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.
