Installation

The PL1877A can be placed on any flat level surface (desk top) that provides the operator with full
visibility of all front panel controls and indicators. It can also be rack mounted using the optional rack-
mount kit.
FCC Interference Warnings
The FCC requires that manuals pertaining to Class A and Class B computing devices contain warnings
about possible interference with local and residential radio and TV reception. Please read these warnings
and all safety information in the Foreword section of this manual.
Equipment Required

Radio interface cable PC with Windows95 or higher
AC voltmeter with dB ranges for measuring
audio levels

Cable Installation Safety Considerations
Interconnecting, communications, and Class 2 dc power cables should be separated from electrical light
or other Class 1 circuits by at least 2 inches. The exception is where Class 1 wiring or power circuits are
run in a raceway, or are metal-sheathed or metal-clad, or are permanently separated from the conductors
of the other circuitry by a continuous and firmly fixed nonconductor such as porcelain tubes or flexible
tubing in addition to the insulation on the wire. Communications cables and in-building wiring should be
listed and marked for the purpose according to NEC Article 800.
Telephone Line Lightning and Over-voltage Protection
The PL1877A has an over-current phone line fuse that protects against occasional extreme fault
conditions that may get past the primary protectors. An example of such a fault condition is a power line
cross. For maximum surge and lightning protection, building primary (over-voltage) protectors should be
installed at the point where the telephone lines enter the radio equipment building. Primary protectors
are usually required by local codes and should be provided by your leased line provider.
