ATTENTION
!
A transient pulse occurs in transistor output when
the external dc supply voltage is applied to the
output common terminals (for example, via the
master control relay). This can occur regardless of
the processor having power or not. For most
applications, the energy of this pulse is not sufficient
to energize the load. Refer to SLC 500 Modular
Hardware Style User Manual, publication
1747-UM011, for more information on transient
pulses and guidelines to reduce inadvertent
processor operation.
