Safety
WARNING!
The SkyZhone product is a line power device conforming to UL
60950-1 and UL 60950-21 standards. The DC voltages (RFT-V
signals) are provided to SkyZhone through the SHDSL connector.
These voltages must be provided by a UL 60950-1 and UL
60950-21 certified power source, typically located at the Central
Office. One such certified power source is the Argus Technologies
CSM35 Modular Converter System (#012-550-B2). Uncertified
power sources can result in injury or death.
Proper Safety Grounding is required to insure proper operation
and protection from lightning strikes and surges. A copper
ground lug is provided on the unit for this purpose. Connect a
length of #10 AWG solid, bare, copper wire to the grounding lug
and firmly tighten the grounding screw (see Figure 20). Connect
the other end of the grounding wire to a grounded surface or
another earth ground such as a metal rod. This ground must be
install before applying power to the unit.
SkyZhone provides both Primary and Secondary lightning and
surge protection to the SHDSL and PoE cable signals. The
Console cable signals are not protected and this cable, which is
not intended for outdoor use, should not be connected when the
unit is installed.
