ATTENTION
A transient pulse occurs in transistor outputs 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 the SLC 500 Modular Hardware
Style Installation and Operation Manual, publication
1747-6.2, for more information on transient pulses and
guidelines to reduce inadvertent processor operation.
