Appendix A.2.2 Status/Control Connections - Liebert Series 610/600T/600 UPS Interconnection Kit
The status/control interface is the Status/Control Terminal Block. The connection of the Status/Con-
trol Terminal Block is described in Figure 137 - Control wiring diagram—Liebert FS cabinet -
manually operated circuit breaker. Refer to this drawing to ensure that proper connections are
performed. In case multiple Liebert FS units are connected to the same UPS DC bus, refer to Figure
129 - Control wiring—external interconnect diagram, Liebert FS cabinet to Liebert Series
610 UPS module to perform the Status/Control connections between each Liebert FS.
This interconnection kit includes Status/Control Connections that enable transfer of signals between
the Liebert FS system(s) and the UPS system such as:
• Circuit breaker status (closed/open); and
• Undervoltage relay coil excitation voltage.

tions (e.g., National Electric Code for USA).
Appendix A.2.3 UPS Configuration - Liebert FS and Liebert Series 610, 600T or 600
To optimize the integration between the Liebert Series 610/600T/600 UPS system and the Liebert FS,
some parameters must be checked on the UPS system:
• The UPS rectifier walk-in time must be set as short as possible. Contact your Liebert representa-
tive if your unit has received the upgraded board that enables the setting of “rectifier walk-in
time” lower than standard.
• Ensure that the “auto battery self test” has either been disabled or upgraded to accommodate
Liebert FS integration.
