Data Line Transient Protection
The nature of the transient phenomenon may extend to the data communication
lines connected to this equipment. It is the responsibility of the customer to
install and connect a data line transient suppression system to correct or prevent
any deficiencies. Such systems must meet the following minimum
requirements:
•
Be aware of the voltage limiting type and must self-recover after passage of
the transient.
•
Insert less than 5 ohms resistance and minimal inductive and capacitive
loading at the operating frequency for non-MIRLAN data lines, in order to
avoid signal degradation.
•
Be installed in accordance with all applicable local, state, and national
electrical codes and regulation.
Note: In certain countries, NCR is able to supply both power and data line transient
suppressors as well as a comprehensive line of power conditioning equipment.
For application data, contact your NCR Customer Services Division
Representative.
