During installation and maintenance, service personnel must wear wrist straps to
prevent damage caused by ESD.
Nokia recommends that you prepare the site before you install the ONT equipment.
In addition, you must control relative humidity, use static dissipating material for
furniture or flooring, and restrict the use of air conditioning.
4.6 Environmental requirements
See the ONT technical specification documentation for temperature ranges for
ONTs.
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.
