Environmental requirements
See the ONT technical specification documentation for more information about temperature ranges.
During operation in the supported temperature range, condensation inside the ONT caused by
humidity is not an issue. To avoid condensation caused by rapid changes in temperature and
humidity, Nokia recommends:
•
The door of the ONT not be opened until temperature inside and outside the enclosure has
stabilized.
•
If the door of the ONT must be opened after a rapid change in temperature or humidity, use a dry
cloth to wipe down the metal interior to prevent the risk of condensation.
•
When high humidity is present, installation of a cover or tent over the ONT helps prevent
condensation when the door is opened.
