Important!
To protect against transient voltages and currents, solid state secondary protectors
must be installed if there is outside wiring, and on all DDI and E&M Tie lines.
These protectors, which contain fast semiconductors in addition to fuses, shall
comply with the requirements for secondary protectors for communication circuits.
Care must be taken to ensure that they are very well grounded to a reliable earth
ground. Install and test the secondary protectors precisely to the installation
instructions of the manufacturer.
