Siemens TPS3 user manual Display Replacement

Display Replacement

The display is field replaceable. Service should only be performed by qualified persons. Deenergize SPD, confirm with appropriate measurement equipment and discharge internal capacitance to ground. Mark locations and carefully disconnect diagnostic cables, contacts, connecting conductors, etc. Unbolt display and replace. Reinstall in reverse.

Note that a sealing gasket between the display and the enclosure is a key component ensuring weather resistance. Replace the gasket whenever the display is removed.

Preventive Maintenance (Inspection and Testing)

Inspection of the TPS3 SPD unit should be performed periodically, to maintain reliable system performance and continued transient voltage surge protection. The large variations in operating conditions encountered by units in the field make it difficult to set a fixed maintenance interval, but inspections utilizing the built-in diagnostics should be performed at least on a weekly or monthly basis.

Corrective Maintenance (Repair)

The Siemens TPS3 unit is designed for years of reliable, trouble-free operation. Unfortunately, in an extreme case, you may experience an alarm condition. In this event, no attempt should be made to repair the TPS3 itself. There are no serviceable parts within the unit. Any SPD that requires service should be appropriately removed from the electrical distribution equipment, and replaced by a new SPD of the same model.
