2-4 How to Install Your Frequency Input Module
Installing the Module
Installation of the frequency input module consists of:
• mounting the terminal base unit
• installing the 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 Frequency Input Module on the
Terminal Base” on page 2-7.
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) 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:

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.
