The ground terminal must be connected to a high quality earth ground point to obtain maximum
protection. Ideally, the ground point should originate at a 1/2-inch copper rod driven at least six feet into
the soil with a No. 16 AWG (or larger) copper wire run to the ground terminal taking the shortest path
possible. Where this is not possible, ground to a nearby water pipe or best available ground.
Equipment Required
Test Equipment
 RF service monitor, or:
 an ac millivolt meter or Sinad meter to measure audio levels
 #1 Phillips screwdriver
Documentation
 remote adapter information, if applicable
 these installation instructions
Cable Installation Safety Considerations
Wiring should conform to the Article 800 of the National Electrical Code. Use listed communication
wiring and cabling for interconnection to other equipment that is suitable for the purpose. Cables should
be marked as
CM
,
CMP
,
CMR
, or
CMX
as appropriate for the use.
Interconnecting data cables should be separated from electrical light or other Class I power cables by at
least 2 inches. The exception is where Class I wiring or power circuits are run in a raceway or in metal-
sheathed, metal-clad, or permanently separately 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. Interconnecting cables longer than 2 meters should be rated VW-1 or FT-1 or
greater.
Power Connections
The desk sets are powered by a listed ac wall transformer supplying a nominal 12 V dc. Optionally, the
unit can be powered by other dc sources. Operating range is 10.5 to 16 V dc.
The power connection pinout is as follows:
