Select a Location to Install the Adapter
Use these guidelines to select where to install the adapter.
• There is no minimum or maximum space requirements between conversion
adapters.
• Be certain that the install location is convenient to route your cable.
• Inside enclosures that provide appropriate environmental isolation.
IMPORTANT
• Do not install the adapter in a position that routes the dropline cable over
any ac power terminals on nearby modules.
ControlNet is an isolated system, connectors and the
shield must not come in direct contact with me tal
enclosure or other ground equipment. This BNC2TNC
provides an isolation from ground when properly
installed.
Do not allow any metal portions of the tap, such as the
universal mounting bracket screws or connectors to contact
any conductive material. This contact could cause noise on
the network.
