Safety of Information Technology Equipment
•
EN 60950-1 2001 - Information technology equipment - Safety - Part 1: generic requirements
What is the Hazard?
A lightning strike into the ground causes an increase in the earth's potential causing a high voltage potential
between the centre conductor and the shield of the coaxial cable. Voltages directly applied onto the centre
conductor "roll off" and arrive after the shield pulse producing a high voltage potential between the centre
conductor and shield of the coaxial cable.
Hazard Impact
A lightning strike causes the ground potential in the area to rise to dangerous levels resulting in harm to
personnel or destruction of electronic equipment in an unprotected environment. It also conducts a portion of
the strike energy down the inner conductor of the coaxial cable to the connected equipment.
Actions to Mitigate Lightning Hazards
See also Figure 1 on Page 13:
1. Do not install the external antenna lines extra-building during a lightning storm.
2. Use a lightning protection device to shunt a large portion of the transient energy to the building
ground reducing an over voltage condition as quickly as possible although it is not possible to
avoid over voltages caused by lightning.
3. Provide primary lightning protection via the operator/customer according to local building codes
as part of the extra-building installation.
4. Use a secondary lightning protection device in building equipment installations with external
antennas to ensure compliance with Clause 7, Connection to Cable Distribution Systems of EN
60950-1, Safety for Information Technology Equipment. The following PolyPhaser Corporation
devices have been approved for use and are available from NovAtel's Sales Department:
DJXZ+24NFNF-A
5. Connect the shield of the coaxial cable entering the building to protective ground through the
primary and secondary lightning protection.
