CAUTION!
Surge suppressors should be installed on any cables where they
enter a building to reduce the possibility of overvoltages or
overcurrents damaging any equipment in the building.

or building at the point where the cables penetrate the building, is
recommended:
•
Cambium 600SS surge suppressors for Ethernet cables
•
Cambium 200SS surge suppressors for DC cables
•
A PolyPhaser DGXZ+06NFNF-A surge suppressor for the
coaxial cable from the GPS antenna
