Drip loop
Fit a drip loop on the PIDU Plus to ODU cable to ensure that any moisture that runs
down the cable into the cabinet or enclosure cannot enter the PIDU Plus. This is shown
in Figure 5-18. Th
e network connection and mains cable should be treated in the same
way if there is a risk that they can carry moisture to the PIDU Plus.

CAUTION
It is possible for moisture to enter the cable due to damage to the outer
protective layer. This moisture can track down the inside of the cable, filling
up the drip loop and eventually finding its way into the PIDU Plus. To protect
against this the outer protective layer of the cable can be opened up at the
bottom of the drip loop to allow this moisture to escape.
