Making Robust and Lasting Connections
Regardless of the grounding point you use, make sure the connections are capable of retaining low resistance
and integrity over time and with exposure to the elements by use of an antioxidant compound. For protection
against corrosion and rust, wrap all connections with a product such as Scotch
®
130C or 2228 Rubber Mastic
Tape.
Grounding Checklist
When grounding a SecureMesh WAN device, use the following checklist to confirm that your installation is
adequately protected from power surges and lightning.
•
Install all lightning and surge protection devices in accordance with UL 96A installation requirements for
lightning protection systems and the NFPA 780 standard for lightning protection.
•
Connect a ground wire from the SecureMesh WAN device to a ground system on the utility pole, tower,
or building.
•
When using outdoor Ethernet cable, use UV protected,
Shielded Twisted Pair (STP) CAT5e cabling that includes a
drain wire. The drain wire and cable shield should be
connected to the appropriate ground location on the
SecureMesh WAN device; typically the ground lug inside the
surge protector or the ground point on the outside of the device.
Leave the other end of the drain wire at the power source
unconnected.
•
Use the proper size down lead to connect the SecureMesh
WAN device on a roof or tower to the ground system.
•
Whenever possible, verify that all points of the ground system
are tied together with less than 5 ohms resistance between any
two points.
For Towers and Rooftops
•
Use the proper size down lead to connect the SecureMesh WAN device on a roof or tower to the
ground system.
•
Run the CAT5e cable inside the tower structure, tying the cable to the tower leg at every 4 feet of
length. For increased protection, run the CAT5e cable through metallic conduit installed on the tower.
