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.
