ATTENTION
!
Whatever field power you supply is connected
to the internal field-power bus. For example, if
120V ac is applied to the power connections,
there will be 120V ac applied to the modules
through the internal field-power bus.
POINT I/O modules to the right of this module
will have this internal power bus voltage
applied, unless you use a 1734-FPD to interrupt
and change the field power-bus voltage.
