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 switch 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.
Switches 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.
Switches which performed the short circuit interruption must be inspected for possible damage. Do not disassemble the switch or open the
switch trip unit.
Replace all damaged insulation materials, conductors and switches. It is recommended that the equipment be hipot tested prior to being
placed back in service.
