1. Rotate keyswitch (2) on terminal base unit (3) clockwise to
position 1 as required for this type of module.
2. Make certain the flexbus connector (7) 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.
4. Position the module (6) with its alignment bar (5) aligned with
the groove (4) 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 (1) is
locked into the module.
6. Repeat the above steps to install the next module in its terminal
base unit.

ATTENTION: The 1203–FM1 may require up to twice the adapter
power supply current of standard flex modules. When installing flex
modules, you can use a maximum of four 1203–FM1 modules with any
flex adapter. As a general rule, each 1203–FM1 requires the power
capacity of two of the standard flex modules, so you cannot install as many
standard modules as you normally would when using the 1203–FM1.
Refer to the following chart to determine the number of 1203 and standard
modules that may be installed together in your system.
