A-2 Transient Protection
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.
• Must be designed to avoid signal degradation for the given interface they are
attached to.
• Be installed in accordance with all applicable local, state, and national electrical codes
and regulation.
