Lightning protection
This section provides instructions for protecting PTP 600 installations against
lightning strike. The purpose of lightning protection is to protect structures,
equipment and people against lightning by conducting the lightning current to ground
via a separate preferential solid path.
The following topics are described in this section:
• Lightning protection zones on
page 2-19
• Grounding considerations on
page 2-20
• LPU configuration options on
page 2-21
• LPU kit on

This section should be treated as a guide only. The actual degree of lightning
protection required depends on local conditions and weather patterns and applicable
local regulations. Full details of lightning protection methods and requirements can be
found in the international standards IEC 61024-1 and IEC 61312-1, the U.S. National
Electric Code ANSI/NFPA No. 70-1984 or section 54 of the Canadian Electric Code.
