4. PROTECTION CONCEPTS
To optimise effectiveness of installed
protection a concept of “Unprotected” and
“Protected” wiring should be followed. Wiring
from the transient source to the Surge
Suppressor should be considered
“Unprotected” and kept remote from all other
wiring (approximately 300mm) where possible.
Wiring on the equipment side of the Surge
Suppressor should be considered “Protected”.
The separation of “Protected” from
“Unprotected” wiring is recommended in order
to minimise the risk of transients conducted on
“Unprotected” wiring cross coupling on to
“Protected” circuits, thus compromising the
level of protection available from the Surge
Suppressor.
Keep other cables and
equipment away
from this area.
