Appendix A.4.2 Status/Control Connections - Liebert Series 300 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 the
Figure 137 - Control wiring diagram—Liebert FS cabi-
net - manually operated circuit breaker
. Refer to this drawing to ensure that the adequate
connections will be performed. If 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
Figure 101 Liebert Series 300 status/control terminal block wiring
The recommended gauge for status/control connection wires is 16 AWG - 600VDC (1.3mm
2
wire sec-
tion). Status/Control wires must be sized and installed in compliance with all applicable local,
regional and national regulations (e.g., National Electric Code for USA).
Appendix A.4.3 UPS Configuration - Liebert FS and Liebert Series 300
To optimize the integration between the Liebert Series 300 UPS system and the Liebert FS, some
parameters must be checked on the UPS system:
• The UPS rectifier walk-in time must be set at a value as low as possible. Contact your Liebert rep-
resentative 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 been either disabled or upgraded to accommodate
Liebert FS integration.
