The I/O wiring and N2 Bus must be “clean,” without electrical noise
transients from nearby lighting, heavy equipment switching, or inductive
loads being driven.
For the N2 Bus, the Transient Eliminator, model TE/JC04C12, made by
Advanced Protection Technologies (APT) is recommended. Refer to the
N2 Communications Bus Technical Bulletin in FAN 636, 628.1, or 1628.1
for more information.
