This Recommendation:

- provides engineering solutions for lightning protection and safety for small-size telecommunication installations under poor earthing conditions. These protection measures are not common requirements for most circumstances and have defined conditions for certain applications. 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 compromise alternatives under poor earthing conditions due to restrictions of circumstance or expense

- is intended to apply to installations powered by a.c. mains and comply with [IEC 60364 series] or national standards bodies on a.c. power installations; - is intended to apply to installations powered by remote power output up to 400 VDC IT system and comply with [ETSI EN 302 099] and [ETSI EN 301 605].

The applied objects in this Recommendation are small-size telecommunication installations which are owned by network operators and controlled by skilled or trained personnel.
