Deployment of ProST in geographical areas that frequently experience severe lightning
storms
The lightning and surge protector protects the ODU-to-IDU CAT 5 cable's six used wires (two -48
VDC wires and four Ethernet Tx and Rx wires) from any electrical surges due to lighting strikes.
The protector is installed outdoors on the CAT 5 cable that connects between the ProST and the IDU
(i.e. SDA-1 Type II or SDA-4S). In other words, two CAT 5 cables are required for the following
connections:
ProST-to-protector connection
Protector-to-IDU connection
Warning: Do not install the lightning and surge protector during adverse weather
conditions when the threat of lightning strike is possible.
Note: The protector unit must be grounded to a low-impedance (low R and low L) ground
system to operate properly.
Note: For pricing and ordering of the PolyPhaser lightning and surge protector, contact
your Airspan representative.
To install the lightning protector:
1. Connect the protector in the direction according to the labels. The end labeled SURGE
accepts the cable from the ProST; the end labeled PROTECTED accepts the cable from the
IDU.
2. Feed the CAT 5 cable through the grommet (for each side). If the RJ-45 connector is
already crimped to the other end, ensure that you have fed the cable through the gland nut
beforehand. The gland nut secures the cable to the grommet.
3. Strip about 0.25" (6.35 mm) of the cable sheath and expose about 0.03" (0.8 mm) of the
strands/wires.
4. Secure the wires to the protector's terminal block using the two spot ties. Each side of the
data and DC assembly has + or – markings to ensure lines entering (surge side) match
lines exiting ( protected side).
5. Mount and ground the protector outdoors with the provided 2 x 8-32 screws according to
the fixing template illustrated below (showing distances between centers of the two
