 1797-5.2 - September 1999

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.

4. Position the terminal base over the 35 x 7.5mm DIN rail A 

(A-B pt. no. 199-DR1).

!

ATTENTION:  Do not force the terminal base into the 
adjacent modules. Forcing the units together can bend or break 
the hook and allow the units to separate and break 
communication over the backplane.

adapter and the flexbus connector is fully retracted.
