DK14 Secondary Protection
The following diagram (see
) shows where secondary protectors must be installed for
outside wiring.
Important!
To protect against transient voltages and currents, solid state secondary protectors
must be installed if there is outside wiring. These protectors, which contain fast
semiconductors in addition to fuses, shall comply with the requirements for
secondary protectors for communication circuits, UL497A.
Care must be taken to ensure that they are very well grounded to a reliable earth
ground. Recommended protectors are available in the fast Series 6 line from
ONEAC® Corp., Libertyville, Illinois 60048, (800) 327-8801. Install and test the
secondary protectors precisely to the installation instructions of thee manufacturer.
