A. LineGuard CAT 5 Modules (Models: 
MMS-CAT5-LAN-RJ45, MMS-CAT5-POE-
RJ45). See Figure 1.  
These models protect one 8-wire Cat 5 cable 
using RJ45 connectors.  
1.  Simply plug the RJ45 jack from the line input 
cable into the “Line” side of the LineGuard 
unit. 
2.  Using a Cat 5 (or better) patchcord, plug 
one end into the “Equipment” side of the 
LineGuard unit and the other side of the 
patchcord into the equipment to be 
protected. 
3.  Mount the LineGuard unit to a solid surface, 
like plywood. Drill a 3/32 hole for the #6 x 
3/4 screw and eyelets provided. See figure 
3. Attach the screw and the eyelet to the 
wall and slide the LineGuard unit over screw 
and tighten. Add a second screw to bottom 
of the LineGuard unit. 
NOTE:  If the LineGuard is to be used as a 
stand-alone unit, connect a minimum #14 AWG 
wire from the ground terminal tab to common 
earth ground with 1 ohm or less (0.5 ohms 
preferred). Use a single ground for the 
LineGuard unit and the protected equipment to 
eliminate differences in ground potential. 
Additional LineGuard units may also be bonded 
together as shown in figure 4 below (dotted 
outline). 
 
B. LineGuard CAT 6 Modules (Models: 
MMS-CAT6-LAN, MMS-CAT5-POE). See 
Figure 2.  
These models protect one 8-wire Cat 6 cable 
using 110 connectors.  
1.  Remove the LineGuard unit’s cover. 
2.  Strip off 1.5" of the jacket from line input 24 
AWG OSP cable and the protected 
equipment cable. 
3.  Insert the OSP cable (“LINE” side) into the 
clip on the printed circuit board. If a shielded 
cable is used, connect the shield to the clip. 
4.  Punch down the line input pairs on the 110 
connectors (“LINE” side) carefully 
maintaining proper wire twist. 
NOTE: The color code is printed on the PC 
board next to the connector. 
5.  Punch down the protected equipment pairs 
on the opposite 110 connectors 
(“EQUIPMENT” side) carefully maintaining 
proper wire twist. 
NOTE: The color code is printed on the PC 
board next to the connector. 
6.  Position and tightly secure a cable tie on 
each cable to provide strain relief next to 
cable exit holes in the LineGuard unit’s 
housing. 
7.  Replace the cover. 
8.  Mount LineGuard unit to a solid surface, like 
plywood. Drill a 3/32 hole for the #6 x 3/4 
screw and eyelets provided. See figure 4.  
Attach the screw and the eyelet to wall and 
slide the LineGuard unit over screw and 
tighten. Add a second screw to the bottom 
of the LineGuard unit. 
9.  When used as a Primary Surge Suppressor, 
connect the grounding strip to a good earth 
ground with a minimum 10 AWG wire. Use 
the ring lug and the machine screw 
provided. Route wire as direct and as short 
as possible. For Isolated Loop applications, 
connect to a single point ground with a 
minimum 14 AWG wire as shown in figure 4. 
10. Additional LineGuard units may also be 
bonded together as shown in figure 4 
(dotted outline). 
 
LineGuard POE Surge Suppressor Wiring 
Conventions: 
•  Shall be wired per TIA/EIA 568A or 568B.  
•  Power Pairs: Blue, Brown (Clamp at 62V).  
•  Data Pairs: Orange, Green (Clamp at 16V). 
 
C. Start Up. 
After the LineGuard unit has been properly 
installed and connected, turn on the power to 
the LineGuard unit and then the protected 
equipment. The installation is complete.
