CRD 3000 Planning Checklist
This checklist is intended for installers who will use the CRD 3000 power line to RF
bridge to extend outdoor range in outdoor lighting systems. To better differentiate
the CRD 3000 from the CPD 3000 and CPL 4000 devices, the checklist below calls
the CRD 3000 an SLB (Street Light Bridge). The CPD 3000 and CPL 3000 devices
are referred to as OLCs (Outdoor Lighting Controllers). Any power line device using
the ISO/IEC 14903-3 standard may be used with the SLB.
1. Determine the best location for the power line segment controller. This is
often in the geographic center of an area of outdoor lights.
2. If the service to the lighting circuit is 240 split phase, system performance
may improve if you locate the segment controller high on an existing light
pole, near the end of the circuit if the existing lighting cabinet does not have
available space. The housing for the segment controller may provide a good
mounting location for the socket for the SLB.
3. Lighting cabinets that use 3-phase service need to have the segment
controller at a location that can easily access all 3-phases and neutral.
4. All communicating devices must share a common set of conductors. If the
lighting cabinet supplies 240 VAC power to the light fixtures, the Segment
controller must be powered with the same 240 VAC.
5. The SLB should ideally be mounted on top of the pole or on top of the fixture
such that the pole does not provide a possible reflection that could interfere
with the signal. If a socket needs to be mounted to the poll, mount it so that
the SLB is 6” from the poll, and positioned so the poll does not shadow the
view from neighbor SLBs. The pole and the sight line to the neighbor SLB
should not form a straight line, as shown below.
