Publication 1794-6.5.16 – September 1998
Installation of the Pulse Counter 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 Pulse Counter Module
on the Terminal Base” on page 2–7.
Mounting the Terminal Base Unit on a DIN Rail
!
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.
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). Proceed as follows:
Position terminal base at a slight angle and hooked over the top
of the DIN rail.
