Installation

4.2.2DC Power Connections

The instructions for installation of DC power connections vary according to the type of UPS intercon- nection kit integrated into your Liebert FS unit. Follow the installation instructions in Appendix A.0 - UPS Interconnection Kits for the relevant UPS interconnection kit installed in your unit.

4.2.3Status/Control Connections

The instructions for installing Status/Control connections vary according to the type of UPS intercon- nection kit that is integrated into your Liebert FS. Follow the installation instructions in Appendix A.0 - UPS Interconnection Kits for the relevant UPS interconnection kit installed in your unit.

4.2.4Ground Connections

A ground connection is available on the Liebert FS (see Figure 29). The electrical contractor must ensure that the Liebert FS is effectively grounded to UPS chassis or UPS ground terminal. The ground connection must be as short as possible. The maximum ground wire size is 1/0 AWG - 600VDC wire (54mm2 wire section). Wire size and installation must comply with all applicable local, regional and national regulations (e.g., National Electric Code for USA). Check all connections with Multi- meter to verify ground continuity. (Refer also to Appendix E.1 - Ground Test Procedure.

! CAUTION

Ensure that all grounds are secure and free of corrosion. Proper grounding is necessary for optimum performance, safety and reliability.
