Installation checklist for humid locations
Humidity kills through cable entries, not through the housing. Five checks before you power up.
Most field failures in humid locations are installation issues, not product issues.
Before mounting
Check that the seal is seated and undamaged. A twisted O-ring still tightens, and still leaks.
Cable entry direction
Point the entry downward. An upward entry collects water even with a sealed gland.
Service loop
Leave a drip loop below the entry so water runs off the cable instead of into the gland.
After the first week
Re-torque the connection and inspect the seal. Thermal cycling loosens joints in the first days.
What to record
Ambient range, medium and installation date — future troubleshooting starts from these three values.
