According the testing standard, each protection
device must have thermal monitoring and must be
isolated safely there defect.

Chapter The internal lightning protection system
. According the American ANSI and IEEE stand-
ard, surge voltage resistance required
for outdoor lighting surge current load kA.32 specifies: "Surge protection devices must
meet IEC 61643.Installation location the lightning and surge
protection
The use surge protection required for safe opera-
tion.
Surge protection devices must
correspond IEC 61643.
However, decisive importance for the protection ac-
tion that the protection level the surge protection
device below the surge voltage resistance the
lights and the LED driver.
The luminaire standard "Fpr 60598-1: 2012-11 Lu-
minaires Part General Requirements and Tests",
Point 4. Powerful lightning current combin-
ation arrestors can arrest the energy-rich currents."
If there direct lightning strike the mast lumin-
aire, large portion the lightning current will flow
directly into the earth, creating potential difference to
the supply cable. Surge protection devices
must correspond the testing standard IEC 61643-
11 and must able arrest surge currents sever-
al thousand amps multiple times without destruction.
