7.4 Maintenance Schedule
The Liebert FS maintenance schedule consists of actions listed in Table 11.
7.5 Record Log
Set up a maintenance log to record scheduled checks and any abnormal conditions.
The log should have space for all metered parameter indications including phase readings, alarm
messages, mode of operation, air filter replacement date and observation notes.
A periodic walk-through inspection of the Liebert FS room is advised to check for visible and audible
indications of problems. Log the inspection, metered parameter indications and any discrepancies.
!
WARNING
Any maintenance on the system should be delayed by at least 10 minutes after system is shut
down to be certain all electronics have discharged. Use appropriate safety precautions to
ensure unit is disconnected and de-energized.
!
CAUTION
Unless specified otherwise, ONLY a Liebert-certified service technician should perform all
maintenance work. Failure to use a Liebert technician for maintenance actions, unless
specifically noted, may void your warranty.

NOTE
The recommended System Visual Inspection every year should include a check and torque of
cabinet DC circuit breaker box lug connections and the DC ground; see the relevant section of
Appendix A.0 - UPS Interconnection Kits for torque requirements.
NOTE
Liebert may determine additional maintenance actions as necessary and issue service or
technical bulletins to address any additions.
NOTE
The optional inlet Air Filter in the cabinet will need to be replaced when it is sufficiently dirty
to significantly reduce the flow of air into the cabinet. Ambient conditions at the installation
site will determine the frequency of replacement if option is installed
