(Cat. No. 1794-IB16)

  

This module mounts on a 1794 terminal base unit.

1. Rotate keyswitch (1) on terminal base unit (2) clockwise to position 2

as required for this type of module.

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 that the pins on the bottom of the module are straight so

they will align properly with the connector in the terminal base unit.

WARNING

!

If you remove or insert the module while the
backplane 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.

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.
