3-8 How to Install Your FLEX Ex Thermocouple/RTD/mV Module
Mounting the 1797-IRT8 Module on the Terminal Base Unit
The 1797-IRT8 module mounts on a 1797-TB3 or TB3S intrinsically
safe terminal base unit.
1. Rotate keyswitch (1) on terminal base unit (2) clockwise to
position 2 as required for this type of module. Do not change
the position of the keyswitch after wiring the terminal
base unit.
2. Make certain the flexbus connector (3) is pushed all the way to
the left to connect with the neighboring terminal base/adapter.
You cannot install the module unless the connector is fully
extended.
3. Make sure the pins on the bottom of the module are straight so
they will align properly with the connector in the terminal base
unit.
4. Position the module (4) with its alignment bar (5) aligned with
the groove (6) on the terminal base.
5. Press firmly and evenly to seat the module in the terminal base
unit. The module is seated when the latching mechanism (7) is
locked into the module.
