Checklist for Connection Cables
Take the following issues into account when installing WMT700:
- How to route the cables depends on the mounting option
selected for WMT700. When mounting to a mast, the cable can
be routed either outside or inside the mast depending on the
mast type and other equipment (for instance, lightning rods)
installed to the mast.
- Make sure that the cable is properly attached to the mast or
cross arm before starting the installation. Otherwise, it may
slip and fall down during the installation procedure.
- Make sure to attach the cable properly to avoid strain on the
connector. Too much strain may cause the cable to fall off,
damage the cable or connector, or make the cable or connector
susceptible to leakage. The recommended minimum bending
radius for the cable is 70 mm.
WARNING Make sure that you connect only de-energized wires.
WARNING Using a long cable between different units (sensors, transmitters, power
supplies, and displays) can cause a lethal surge voltage, if a lightning
strike occurs in the vicinity. Always apply proper grounding procedures
and follow the requirements of the local Electrical Code.
WARNING Do not install WMT700 when there is a risk of thunderstorm or lightning
activity in the area.
