! 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

7.5Record 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.
