ControlNet Ex Tap Terminator Installation Instructions
(Cat. No. 1797-TCAP)
Use this document as a guide when you install a ControlNetTM Ex tap
terminator. This document will be packaged with 5 tap terminators.
About the Tap Terminator
The tap terminator allows you to install extra taps on your trunk line
without installing ControlNet Ex nodes. The tap terminator facilitates the
maintenance of your network by providing termination of a tap not in use;
holding a space for a node to be added in the future.
The tap terminator can be used on any number of taps in your ControlNet
Ex system. Refer to the ControlNet Ex Coax Media Planning and
Installation Manual, publication CNET-IN002A-EN, to determine how
many taps you can install in your system.
Installing the Tap Terminator
1. Remove the dust cap from the exis ting tap.
2. Install the tap terminator over the exposed end of dummy as shown
below.

ControlNet Ex Tap Terminator Installation Instructions 3
Describing the ControlNet Ex System Diagram
A maximum of 48 ControlNet ExTM nodes may be connected together by
820ft (250m) of coax cable and 48 taps. The distance to increases to 3280ft
(1000m) when you use only 2 taps. See the table below for more
information.
The fiber media of the 1797-RPFM can be installed in a hazardous location
(Zone 0, 1 or 2; Class I, Zones 0, 1, and 2; Class I, Divisio n 1 and 2; Class
II, Division 1 and 2; Class III, Division 1 and 2) to connect two
1797-RPFM modules or they can be installed through different locations
into the non-hazardous location to connect the 1797-RPFM with any
approved as sociated appar atus.
All cables and fibe r media that are not light blue must be marked as I S
using the 1797-EXMK marking kit or other locally approved IS
identification and/or segregation method.
During the installation of the Co ntrolNet Ex system, all m etallic parts must
be isolated to prevent an earth connection (high voltage withstanding of
isolating material must be > 500V ac).
