Wire to a 1797-TB3 or 1797-TB3S Terminal Base Unit
Connect wiring to the terminal base as shown below.
Wire the Module
Make wiring connections to the module terminal base unit according to the
wiring table below.
ATTENTION
For VORTEX signals and magnetic pickups only.
Connect the channel ground terminals to the chassis ground terminals to
achieve the EMC protection class. Because, in this case, the intrinsically safe
circuit is grounded, and you must check the installation requirements of the
respective country for this context.
WARNING
Make certain that you power this module with an intrinsically safe power
supply. Do not exceed the values listed in the specifications for this module.
If you connect or disconnect wiring while the field-side power is on, 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.
