6.5.5 Regular Startup Procedure
6.5.6 Inspection Before Regular Startup
The following verifications must be done before performing a regular startup of the Liebert FS (see
6.5.7 - Starting up the System):
1. Make sure the Liebert FS is properly secured to the floor with the Liebert-provided mounting kit
and in compliance with the floor mounting instructions in 4.1 - Cabinet Floor Mounting.
2. Check for coolant leaks in and around the Liebert FS unit.
3. Ensure that Liebert FS cabinet panels are in place on the cabinet and that no tools have been left
in the cabinet
4. Ensure that the Liebert FS Main circuit-breaker (optional) or the customer-provided external DC
disconnect switch is open
5. Verify that the AC Auxiliary Backup Power is connected and powered by closing fused disconnect
or wall disconnect and check if the Control Panel is ON and with no warning or fault messages
displayed.
The Liebert FS may now be started up.
6.5.7 Starting up the System
Powering Up the Liebert FS
Once AC voltage is applied to the Liebert FS, the Liebert FS Control Panel will boot up. Its screen will
begin to illuminate after 5 to 10 seconds and then display a series of boot up protocols.
Booting Up
1. It takes about 25 seconds to load and initialize the primary application software at STARTUP or
after reset.
2. Title block and firmware versions will be displayed (see Figure 82). If the secondary DSP does
not boot up properly, versions for the secondary DSP may be corrupted or zero.
3. EEPROM checksum will be calculated and compared with the stored value. EEPROM checksum
fault will be generated if they do not match. For this case, default values are loaded for
parameters in RAM. However, EEPROM contents are not changed.
4. Response from secondary DSP will be checked. “INTERPROCESSOR COMM FAULT” will be
generated if the communication is not set up properly. The controller will reset itself for this case.
5. Previous operation command (STARTUP or SHUTDOWN) will be retrieved to determine the
current operation mode.
6. Option status is checked. Current available options are VIB and DCM.

CAUTION
The Initial System Startup shall be performed ONLY under the supervision of a Liebert
technician to ensure proper system operation. Failure to abide by instructions provided herein
may void your warranty.
NOTE
A regular startup is any startup after the Initial System Startup.
!
CAUTION
The following procedure assumes that the Initial System Startup has been performed under
the supervision of a Liebert technician.

CAUTION
Do not attempt to run the system unless the system loads valid parameters.
