A-2 Appendix A: Transient Protection

Be listed by the accepted safety organization for the country involved (UL, CSA, VDE, ETL, and so on) and the installation must conform to local, state, and national electrical codes and regulations.

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 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 regulations.

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.
