Operation

Validation of Control Parameters Setup

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”.

Initiating Liebert FS Startup Sequence

NOTE

Startup procedures will vary for each UPS model.

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

NOTE

Optional UPS interconnection kits include circuit-breakers then referred to as “Liebert FS Main circuit-breaker”.

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.

Liebert FS Startup Sequence

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.

6.6Shutdown Procedure

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- Configurable Parameters.
