FLEX Ex Frequency Input Module 9

Publication

1797-5.9 - June 2010

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.
