Check List for Connection Cables
Take the following issues into account when installing WMT700:
- Routing of 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.
- It is important 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.
