PREVENTIVE MAINTENANCE - Inspection and Cleaning

Inspection of the SPD should be performed periodically to maintain reliable system performance and continued transient voltage surge protection. While it is difficult to establish a preventive maintenance schedule because conditions vary from location to location, inspections for failed LEDs and other signs of trouble utilizing the built-in diagnostics should be performed on a routine basis (weekly or monthly).

REPLACEMENT PARTS

The only replaceable item in the SPD is the Display Board Assembly (see Figure 5), and must be replaced by a qualified electrician.
