Emerson Series 600 User Manual

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.

The electrical connections to the Liebert FS are:

• DC  power
• Status/control (upgraded)
• Ground
• Auxiliary backup power
• Remote monitoring—optional

Power and Status/Control wiring must be run in separate conduits or cable trays. Refer to Appendix 

D.0 - Installation Drawings for locations of the various electrical connections between Liebert FS 

system(s) and UPS system.

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).

Power and Status/Control wiring must be separated.
