Summary:
|
This Recommendation:
- provides engineering solutions for lightning protection and safety for small-size telecommunication installations (STIs) under poor earthing conditions. These protection measures are not common requirements for all kinds of circumstances and have defined conditions for application respectively. If these installations have equivalent inherent capacity and function, the same results can be acquired.
- is not intended to replace traditional rules on bonding configurations and earthing. These protection measures are compromised alternatives under poor earthing conditions due to the restriction of circumstances or expense.
- is intended to comply with [IEC 60364-4-41] or national standardizing bodies on a.c. power installations.
The applied objects in this Recommendation are the telecommunication installations whose power consumption is less than 200 Watt and occupation area is less than several square meters. The installation may be single equipment or a case or a site assembling several interconnected equipments in close proximity.
