Figure 22: Extra Surge Protector Installation
The recommended surge protector is the Transient Eliminator, model
TE/JC04C12, manufactured by Advanced Protection Technologies (APT).
The device protects the N2 Bus from indirect lightning. It shunts both
common and normal mode voltage surges to ground repeatedly without
damage to N2 Bus components.
!
CAUTION: The device is capable of protecting the N2 Bus from
indirect
lightning strikes,
not direct
lightning
strikes. A direct strike may cause actual damage to
the bus cable or surrounding property. An indirect
lightning strike may cause induced voltage transients
that could cause electronic malfunction without
visible damage to equipment if the equipment was
not protected.
Use the surge protector with the standard N2 Bus wiring. Do not use it
with any other type wiring, such as leased line. If you need surge
protection for other wire types, contact APT or another transient noise
protection company.
