Installing Ethernet Lightning Arrestors
If you have determined that it is appropriate to install lightning protection for your system,
the following general industry practices are provided as a guideline only:
Installing the Line Protector Unit
This section describes the steps required to install the Ethernet line protector. It is
recommended to pre-wire the LP device and test all connections before final outdoor
installation. Connect the LP unit according to the direction it is labeled. Each side of the
unit has been labeled SURGE and PROTECTED for this purpose. Do not switch
Ethernet wires from input to output. The unit may be mounted/grounded on a nearby
plate or bulkhead panel that is bonded to an earth-ground system.
Installing the POE Line Protector Unit
Do not install during adverse weather conditions when the threat of a
lightning strike is possible.
Connect this unit in the direction it is labeled. Each side of the unit has been labeled
SURGE and PROTECTED for this purpose. Do not switch Ethernet wires coming in and
going out. For
–
IG (isolated ground) units, they are marked 2 X FEED and 2 X RTN
(RETURN). The unit may be mounted/grounded on a nearby plate or bulkhead panel
that is bonded to an earth-ground system.
1
. Mounting: Ground the unit with provided 2 X 8-32 screws to the pattern below.
2
. Terminal Block: Wire gauge; 16-
28 AWG. Wire strip length; 0.25”. Tightening
torque; 2.21 lb-in. (0.25 N-m).
3
. Lid: 4 X M4 X 20 mm screws. Be sure the neoprene gasket on the lid is not loose and
is properly fitted into the groove. Tightening torque; 11 lb-in. (1.24 N-m).
Outdoor Units: Be sure all conduit fittings are used and torqued to meet environmental
specifications. Conduit fittings have O-rings to ensure environmental seal.
FOR CORRECT OPERATION, IT IS VERY IMPORTANT THAT THE
LINE PROTECTOR IS PROPERLY CONNECTED TO A LOW IMPEDANCE (LOW R
AND LOW L) GROUND SYSTEM.

Note: LP terminal block assignment is identical for both screw-type and 110Connect.
