Caution
Statement 1030
Warning Connect the unit only to DC power source that complies with the safety extra-low voltage (SELV)
requirements in IEC 60950 based safety standards.
Warning When installing or replacing the unit, the ground connection must always be made first and
disconnected last.
Do not locate the antenna near overhead power lines or other electric light or power circuits, or
Warning
where it can come into contact with such circuits. When installing the antenna, take extreme care
not to come into contact with such circuits, because they may cause serious injury or death. For
proper installation and grounding of the antenna, please refer to national and local codes (for
example, U.S.:NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code,
Section 54).
Installation of the equipment must comply with local and national electrical codes. Statement 1074

conductors.
Power cables in excess of 140 feet in length must have protective devices installed that are UL listed
3.
to UL 492, UL497A or UL497B, UL497C, and UL1449.
The BS must be connected to a power supply/rectifier that is IEC 60950-1 certified (UL listed to
4.
UL60950-1 in North America) having a SELV output.
5. All power and ground conductors must be mechanically supported to avoid strain of the wires and
connection points.
6. There must not be a switch or disconnect device installed in the ground cabling.
A UL listed disconnect device, such as a circuit breaker, must be installed between the power supply

and BS chassis connections. The BWX 8415 BS requires a 60V, 15A, 1 sec. max break time circuit
breaker.
Power-interconnect wires between the power supply/rectifier and the BS unit must have heat shrink
