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.
