Troubleshooting the Power Xpert SPD

Many SPD failures result from improper installation . Once the
Power Xpert SPD is installed properly, it is a highly reliable unit .
If the SPD does not function properly, first confirm that it is installed
properly . See Installation on page 3 .
If the SPD malfunctions after it has been operating routinely, refer
to Table 6 . This troubleshooting chart identifies possible causes
and solutions to the malfunction . Further assistance may be
obtained by calling Eaton's application engineers at 1-800-809-2772
or email SPD@eaton.com, including being directed to the warranty
process if applicable .
