Installation

6.Attach a large diameter washer, a lock washer and a nut to each hex flange bolts as described in Figure 25 and Figure 155.

7.Check the bubble level on the floor of the cabinet on the right hand side of the Power Conversion Module (see Figure 24). The Liebert FS is sufficiently level when the bubble is within the outer of the two circles. If the bubble is outside the outer circle, use the leveling feet to adjust until bubble is within the outer circle.

8.Once cabinet is level, firmly tighten down all hex flange bolts with nuts. The bolts must be tightened to 40 foot-pounds (54 N-m) of torque.

4.2Wiring Connections

4.2.1General Wiring Considerations

! CAUTION

A qualified electrical contractor must perform all electrical connections. The wires (DC power, ground, upgraded status/control and auxiliary power supply) that connect the Liebert FS system(s) to the UPS system are field-supplied or by Liebert as an option. Wire size and installation must comply with all applicable local, regional and national regulations (e.g., National Electric Code for USA).

The electrical connections to the Liebert FS are:

DC power

Status/control (upgraded)

Ground

Auxiliary backup power

Remote monitoring—optional
