SPD module reseating

SPD module reseating means pulling the plug-in surge protection module out of its socket and putting it back in. Inverter manuals list it as a fix for the DC SPD warning (Warn0040) and the AC SPD warning (Warn0100), which are raised when a surge protector may be exhausted. Start by checking the SPD status indicator by eye. Reseat the module only if the indicator is green. If the indicator is red, reseating will not help. Replace the SPD module instead. On stand-alone SPDs, a red LED together with an audible alarm points to protection that is compromised or lost after a significant surge event. The listed fix is replacement. If one phase is red because of an extended temporary overvoltage, find and correct the overvoltage source before you install a new SPD. If the warning is still there after reseating, contact the manufacturer's post-sales service.

<!-- review notes

• sentence 2: support check: partial - The passages list remove-and-reinstall as the fix for Warn0040 and Warn0100 when the indicator is green, but they never say the warnings are raised when a surge protector may be exhausted.
• sentence 4: support check: partial - Red means replace the SPD module, but the passages never say reseating won't help.
• sentence 5: support check: partial - The passages cover red LEDs with an audible alarm, a significant surge event or compromised protection as causes, and replacement as the fix. They don't say the condition applies only to stand-alone SPDs, and some rows describe it as a neutral/ground or phase condition.
• sentence 7: support check: partial - The passages say to contact post-sales service if not corrected, but only some rows say this. Warn0100 in u21 and in the Warn0100 line of u17 omit it.
• sentence 4: review: partial - The rows say a red indicator means replace the SPD module, but they never say that reseating will not help. -->
