3-4 How to Install Your FLEX Ex Analog Modules
Installing the Module
Installation of the analog module consists of:
• mounting the terminal base unit
• installing the analog I/O module into the terminal base unit
• installing the connecting wiring to the terminal base unit
If you are installing your module into a terminal base unit that is already
installed, proceed to “Mounting the Analog Modules on the Terminal Base”
on page 9.
Mounting on a DIN Rail
1. Remove the cover plug in the male connector of the unit to which you
are connecting this terminal base unit.
2. Check to make sure that the 16 pins in the male connector on the
adjacent device are straight and in line so that the mating female
connector on this terminal base unit will mate correctly.
3. Make certain that the female flexbus connector is fully retracted into
the base unit.

ATTENTION: Make certain that you power this terminal base
module combination with an instrinsically safe power supply. Do
not exceed the values listed in the specifications for the terminal
base or module.
Do not use the unused terminals on the terminal base unit. Using
the terminals as supporting terminals can result in damage to
modules and/or unintended operation of your system.

ATTENTION: Do not remove or replace a terminal base unit
when power is applied. Interruption of the flexbus can result in
unintended operation or machine motion.
