9. Maintenance
Before installing or maintaining this equipment, it is extremely important to read this manual and be sure that all equipment drawings
and schematics are reviewed and clearly understood. If there are any questions concerning this manual or any of the installation or
maintenance procedures and/or requirements, please contact a Tripp Lite representative before proceeding.
Inspection and maintenance should only be performed on equipment that has been de-energized and electrically isolated, so that no
accidental contact can be made with energized parts.
9.1 Short Circuits and Overloads
Do not attempt to re-energize a circuit breaker after a short circuit or overload until the cause of the event has been identified and
corrected. Failure to correct the cause of the event may result in equipment damage, fire, severe injury or death.
Circuit breakers will normally prevent electrical damage except at the point where the short circuit occurred. High mechanical stress
developed by short circuit currents may cause damage to conductors, insulation or other components. After a fault, thorough inspection of
the entire system must be made to verify that there is no damage.
Circuit breakers which performed the short circuit interruption must be inspected for possible damage. Do not disassemble the breaker or
open the breaker trip unit.
Replace all damaged insulation materials, conductors and circuit breakers. It is recommended that the equipment be hipot tested prior to
being placed back in service.
