Leveling channels - If the enclosure is mounted on leveling channels, bond the channels to the woven wire mesh with
solid-steel wire jumpers of approximately the same gauge as the woven wire mesh. Bolt the enclosure to leveling channel,
front and rear.
Signal and power levels - Refer to section, Cable Separation and Routing, for guidelines.
Solid-bottom tray - Use steel solid bottom cable trays with steel covers for low-level signals most susceptible to noise.
