Wiring guidelines
Safely pulling the interconnection cable
•
Connect a mouse line to the outer jacket of the radar interconnection cable so that the
strain of pulling is transferred to the stronger outer jacket of the cable. Use some small
cable ties to secure the mouse line to the outer jacket as well if there is sufficient clearance.
•
Tape the conductors and tape the RJ45 connector to the mouse line so that it does not
get caught and bent backwards.

Do:
•
make drip and service loops
•
use cable-ties on all cables to keep them secure
•
solder/crimp and insulate all wiring connections if extending or shortening the cables
•
use the appropriate length of ready-made interconnection cable
•
leave room adjacent to device to ease plugging and unplugging of connectors
Do not:
•
make sharp bends in the cables
•
run cables in a way that allows water to flow down into the connectors
•
run the data cables adjacent to radar, transmitter, or large/high current carrying cables or
high frequency signal cables
•
run cables so they interfere with mechanical systems
•
run cables over sharp edges or burrs
•
attach a mouse line directly to the Ethernet cable or connector
!
Warning:
Before starting the installation, be sure to turn electrical power off. If power
is left on or turned on during the installation, fire, electrical shock, or other serious injury
may occur.
!
Warning:
The positive supply wire (red) should always be connected to (+) DC with
the supplied fuse or a circuit breaker (closest available to fuse rating). Be sure that the
voltage of the power supply is compatible with the unit.
