1. Once the Control Panel has successfully booted up, the Control Panel will display the Main 

Screen (see Figure 55).

2. Verify the Control Parameters values are correct. (Consult Table 9 and the relevant UPS 

Interconnection Kit Handbook for choosing the proper Control Parameters values).

3. Adjust the Control Parameters values if necessary (see 6.4.1 - Screen Tree Menu Functions). 

for instruction on how to change the values of the Control Parameters) then press “F6 DONE”.

1. Once sufficient DC voltage is applied to the UPS DC Bus, the Liebert FS will be able to transition 

from the OFF Mode to Startup Mode, unless system was previously Shutdown by command.
The following action is conditional on the UPS interconnection kit that has been installed on your 

Liebert FS:

• Standard UPS Interconnection Kit (IKIT-STD)

The Standard UPS interconnection kit (IKIT-STD) includes a fused Power Terminal Block. It is 

recommended for maintenance use to have an external disconnect switch installed between the 

UPS and the Liebert FS.
Close the customer-provided external disconnect switch at the time indicated by the UPS startup 

procedure.

• Optional UPS Interconnection Kit

Open the Liebert FS cabinet front door and close the Liebert FS main circuit-breaker at the time 

indicated by the UPS startup procedure. Close the cabinet door.

2. The Control Panel will then show the Main screen (see Figure 55). The System Mode should read 

“OFF”. The Liebert FS will actively check for presence of sufficient voltage to allow system 

startup.

3. As soon as the UPS DC bus voltage is greater than Vcharge, the System Status will change from 

“OFF” to “STAND BY”. The “F1 STARTUP” key will then be enabled.

4. Press the “F1 STARTUP” key.

As soon as the “F1 STARTUP” key is pressed, the Liebert FS will launch its startup sequence. This 

will progressively lead the Liebert FS through the different Modes of Operation (STAND BY, STAR-

TUP, CHARGE) to eventually reach a ready state of idling (READY Mode) once it is completely 

charged up. The automatic transition between modes is described in 5.2 - List of System User-Con-

figurable Parameters.

There are two ways the Liebert FS may enter a Shutdown sequence: either a) following a Liebert FS 

discharge down to SOC = 0%; or b) following a user-initiated command.
In any Mode, except OFF Mode, the user may command the Liebert FS to transition in SHUTDOWN 

Mode by pressing the “F2 SHUTDOWN” key. This action is recommended for normal shutdown of the 

system. In this condition, the Liebert FS will not discharge to support an outage. You will be asked to 

confirm “Yes” or “No” to SHUTDOWN. Press “Yes” to confirm shutdown and put system in SHUT-

DOWN mode.
For more information concerning the SHUTDOWN Mode, please refer to 5.2 - List of System User-

NOTE
Startup procedures will vary for each UPS model.

Optional UPS interconnection kits include circuit-breakers then referred to as “Liebert FS
