ETSI ONT safety guidelines

ESD safety guidelines

The ONTs comply with BS EN 61140.
1.3.1 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.
1.3.2 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.
1.3.3 Protective earth
Earthing and bonding of the ONTs must comply with the requirements of local electrical codes.
1.4 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 you enter the
TELCO Access portion of the ONT.
During installation and maintenance, service personnel must wear wrist straps to prevent damage
caused by ESD.

Laser safety guidelines

Observe the following instructions when you perform installation, operations, and maintenance
tasks on the ONT equipment.
