Site Preparation

2.4.2Status/Control Connections

Site preparation for Status/Control connections vary according to the type of UPS interconnection kit provided with your Liebert FS.

Liebert recommends making Status/Control connections on the UPS system side. For details, refer to 4.2.3 - Status/Control Connections.

2.4.3Grounding Connections

A grounding wire must be connected from the Liebert FS to the UPS ground terminal. Identify in advance the location of the grounding terminal on the UPS system. For further details, see 4.2.2 - DC Power Connections.

2.4.4AC Power Connections

Plan for the availability of a dedicated 110 or 230VAC, 50 or 60Hz circuit with branch circuit protec- tion as a source for AC auxiliary power supply to the Liebert FS. This AC power must be rated for 500VA and must be located either on the output circuit of the UPS system or on another UPS-pro- tected circuit. A qualified electrical contractor should make arrangements for this connection to be permanent.

The field-supplied AC wire must comply with all applicable local, regional and national regulations (e.g., National Electric Code for USA). An 18 AWG (0.82mm2) cable is recommended for this connec- tion.

For details, see 4.2.5 - AC Auxiliary Control Power Supply Connections and Appendix F.0 - Auxiliary Backup AC Power Supply.

2.4.5Remote Monitoring Connections—Optional

If the optional Data Collection Module (DCM) is provided with your Liebert FS system, plan to have communication cables (local network connection, phone line) installed to support the remote notifica- tion and/or monitoring options chosen.

For details, see 4.2.6 - Remote Monitoring Connections—Optional.
