2.3 Electrical safety guidelines
This section provides the electrical safety guidelines for the ONT equipment.
2.3.1 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.
2.3.2 Cabling
The following are the guidelines regarding cables used for the ONT equipment:
• All cables must be approved by the relevant national electrical code.
• The cables for outdoor installation of ONTs must be suitable for outdoor use.
• POTS wiring run outside the subscriber premises must comply with the
requirements of local electrical codes. In some markets, the maximum allowed
length of the outside run is 140 feet (43 m). If the outside run is longer, NEC
requires primary protection at both the exit and entry points for the wire.
2.3.3 Protective earth
Earthing and bonding of the ONTs must comply with the requirements of local
electrical codes.
Note 1 — The ONTs comply with the U.S. National Electrical
Code. However, local electrical authorities have jurisdiction
when there are differences between the local and U.S.
standards.
Note 2 — The ONTs comply with BS EN 61140.
