Troubleshooting

If status failure indication occurs or Form C relay has changed states, a qualified electrician shall first determine if the systems voltage and proper phasing exists.

If the SPD remains in an alarm condition once the electrician is satisfied that the electrical system and its connections are normal, the unit should be repaired. At this point consult the factory, having available the following information:

Unit identification number – (refers to the model and serial numbers detailed on the data label and is located on the front or upper left [hinge] side of the enclosure.)

Nature of problem – (including status of all status indicators and alarms).

Servicing

ONLY QUALIFIED PERSONNEL SHOULD PERFORM MAINTENANCE ON THE SYSTEM.

HAZARDOUS VOLTAGES ARE PRESENT INSIDE THE UNIT DURING NORMAL OPERATIONS.

ELECTRICAL SAFETY PRE-CAUTIONS MUST BE FOLLOWED WHEN SERVICING THIS UNIT.

TO PREVENT RISK OF ELECTRICAL SHOCK, TURN OFF AND LOCK OUT ALL POWER SOURCES TO THE UNIT BEFORE SERVICING UNIT.

(For servicing assistance, contact your local Liebert Sales Representative or Liebert at 800-288-6169 or 607-724-2484.)

Corrective Maintenance

The Liebert SPD is designed for years of trouble-free operation. However, even the most reliable equipment may fail under abnormal conditions.

Diagnostic indicators are provided to indicate when the unit needs replacement (see individual SPD operation of this manual for details). To ensure continuity of surge protection, failed units should be replaced at the earliest convenient service opportunity.

When replacing surge modules, other components should be inspected for damage and replaced if necessary. Standard electrical troubleshooting procedures should be used to isolate problems other than failed surge current diverter modules.

When replacing components, for continued proper operation and safety, replace only with identically rated components. Please contact factory for information on replacement parts.

Preventative Maintenance (Inspection and Cleaning)

Periodic system inspections, cleaning, and connection checks are recommended to ensure reliable system performance and continued surge transient protection.

It is difficult to establish a schedule for preventative maintenancesinceconditionsvaryfromsitetosite. Inspections for failed surge modules using available diagnostics should be done routinely (weekly or monthly).
