Why is there moisture inside my X1/X2?

Differences in temperature and humidity between the inside of the housing and the outside (e.g. sitting in direct sunlight, getting splashed with cold water, etc.) allows moisture to deposit on the walls of the X1/X2 connector protectors. This is normal and no cause for alarm. there should never be more than a few drops inside the units. If there is more water in there, disconnect lead from power supply, open unit and inspect seal for damage.
