Esd Safety Guidelines; Environmental Requirements - Nokia ONT Product Manual

ANSI ONT safety guidelines

ESD safety guidelines

4.4.1 Power supplies
The use of any non-Nokia approved power supplies or power adapters is not supported or
endorsed by Nokia. Such use will void any warranty or support contract with Nokia. Such use
greatly increases the danger of damage to equipment or property.
4.4.2 Cabling
The following are the guidelines regarding cables used for the ONT equipment:
• Use only cables approved by the relevant national electrical code.
• Use cables suitable for outdoor use for outdoor installation of ONTs.
• The ONTs have been evaluated for use with external POTS wiring without primary protection
that may not exceed 140 ft (43 m) in reach. However, the power cable must not exceed 100 ft
(31 m).
4.4.3 Protective earth
Earthing and bonding of the ONTs must comply with the requirements of NEC article 250 or local
electrical codes.
4.5 ESD safety guidelines
The ONT equipment is sensitive to ESD. Operations personnel must observe the following ESD
instructions when they handle the ONT equipment.
CAUTION
Service Disruption
This equipment is ESD sensitive. Proper ESD protections should be used when entering the
TELCO Access portion of the ONT.
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.
