18 How to Install Your Analog Module
Installing the Module
Installation of the analog module consists of:
•
mounting the terminal base unit
•
installing the analog 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 Module on the
Terminal Base Unit on page 2-22.
Mounting the Terminal Base Unit on a DIN Rail
1. Remove the cover plug (if used) 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. Position the terminal base on the 35 x 7.5mm DIN rail A (A-B pt.
no. 199-DR1; 46277-3; EN 50022) at a slight angle with hook B
on the left side of the terminal base hooked into the right side of
the unit on the left. Proceed as follows:
Figure 2.1
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.
Position terminal base at a slight angle and hooked over the
top of the DIN rail.
