Troubleshooting

Many SPD failures result from improper installation . Once the SPD
is installed properly, it is a highly reliable unit . The most common
reason for SPD failure is a temporary overvoltage (TOV) condition .
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 5 . This troubleshooting chart identifies possible causes
and solutions to the malfunction . Further assistance may be
obtained by calling Eaton's Technical Resource Center (TRC)
and speaking to a surge protection application engineer at
1-800-809-2772 or email SPD@eaton.com, including being
directed to the warranty process if applicable .
