Chapter 2 Install a 1768 ControlNet Communication Module
Connect the Module to a
ControlNet Network You can connect the module to the ControlNet network by using a tap (catalog
number 1786-TPR, 1786-TPS, 1786-TPYR, 1786-TPYS, or 1786-TCT2BD1)
or a network access cable (catalog number 1786-CP).
See the ControlNet Coax Media Planning and Installation Guide, publication
CNET-IN002 , for additional information.
The 1768-CNB and 1768-CNBR modules have a network access port (NAP)
available.
Perform the following steps to connect the module to the network by using a tap.
1. Remove and save the dust caps from the ControlNet network taps.
WARNING: If you connect or disconnect the communication cable with power
applied to this module or any device on the network, an electrical arc can occur.
This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
ATTENTION: 1768 modules are not designed for removal and insertion under
power. Removal or insertion of a 1768 module while power is applied can result
in module damage or unintended operation.
WARNING: The NAP is intended for temporary local programming purposes
only and not intended for permanent connection. If you connect or disconnect
the NAP cable with power applied to this module or any device on the network,
an electrical arc can occur. This could cause an explosion in hazardous location
installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
ATTENTION: Do not allow any metal portions of the tap to contact any
conductive material. If you disconnect the tap from the module, place
the dust cap back on the straight or right-angle connector to prevent
the connector from accidentally contacting a metallic grounded surface.
