Section 3 — Safety Information
AA
WARNING!
The RFC-1 Remote Facilities Controller and the RP-8 Relay Panels should be installed only by
qualified technical personnel . Incorrect or inappropriate installation could result in a
hazardous condition.
The RFC-1 Remote Facilities Controller is registered with the Federal Communications
Commission and certified to meet specific safety requirements. It is extremely important that
the RFC-1 not be modified in any way . Modification of this equipment will void the FCC
certification, void the warranty, and perhaps pose a hazard to the user of this equipment or to
maintenance personnel of your local telephone company.
Service of the RFC-1 Remote Facilities Controller should be performed only by qualified
technical personnel who are familiar with the implications of FCC Part 68 registration.
Extreme caution should be used if the RFC-1 Remote Facilities Controller case is opened
without first being disconnected from the telephone line and the RP-8 Relay Panels. High
voltages may be present on telephone lines, and although the RFC-1 is powered by 12 volts
AC from a "wall plug" transformer, failure of this transformer could cause dangerous and
potentially lethal voltages to become present. Only the supplied transformer should be used.
The RFC-1 contains self-resetting "fuses" that protect it from excessive current. If these are
replaced, the replacement devices should be of the same type and rating.
Depending on the installation, the RP-8 Relay Panels may be connected to 120 volts AC. If
this is the case, use extreme care when working in the vicinity of these panels . Disconnect all
sources of high voltage AC before contacting these panels.
The RFC-1 Remote Facilities Controller and the RP-8 Relay Panels are designed for indoor use
in a dry location. Installation and operation in other locations could be hazardous.
