ECLIPSE INSTALLATION MANUAL
Installing Lightning Surge Arrestors
ODU 600 has an internal arrestor. An external arrestor at the ODU is not required
unless specified by the site owner or operator.
Whi le an internal matrix-type arr estor is standard on ODU
600, an additional external ODU arrestor may stil l be required
to compl y with local installati on practi ces in regi ons that
experience severe lightni ng strikes.
An arrestor should also be installed at building entry to provide added protection to
the indoor equipment, including that of other vendors. But where specified by the
site owner or operator, it must be installed.
For more information on recommended installation practices for lightning pro-
tection, refer to the Best Practices Guide.
For external arrestor installations, the supplied arrestor (Universal Lightning
Arrestor) is an in-line matrix type. It has a dc-blocked RF path with multiple pro-
tection stages in the parallel dc path. These arrestors are designed to withstand
repeated strikes and in the event they do fail, to hard-fail so as not to cause uncer-
tain or intermittent operation.

Lightning Arrestor Kit
The ULA (Universal Lightning Arrestor), type 108-1118B-A, is a compact cylindrical
inline arrestor.
Two versions are available, N-female to N-female, or N-male to N-female
The ULAs are bi-directional - they can be installed with either connector facing the
ODU.
The ULA kit includes a ground wire, crimp lug, washer, nut and O-ring. The ground
wire is terminated at one end for connection to the ULA, and is un-terminated at the
other to enable correct cutting-to-length and the fitting of the crimp lug.
