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 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. Interconnecting cables longer than 2 meters should be rated VW-1 or FT-1 or
greater. The recommended cable kits conform to these requirements.
Electrostatic Discharge (ESD) Protection
This equipment has ESD protection circuitry which provides a high degree of protection against ESD and
power and telephone line surges. The circuitry shunts the transient currents to earth ground through the
GND terminal.
Terminal 8 inside the desk set on the TS1 terminal block can be used as an earth GND terminal. The
GND 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 6 feet into the soil with
a No. 16 AWG (or larger) copper wire run to the GND terminal taking the shortest path possible. Where
this is not possible, ground to a nearby water pipe or best available ground.
