Tsunami MP.11a Antenna Installation Guide 
Check with a qualified electrician if you are in doubt whether the surge arrestor and cable connectors are 
properly grounded. 
Only after you have verified that each of the items is properly grounded, replace the surge arrestor and 
disconnect the cables from the grounding system in exactly the reverse order of the previous steps. 
SURGE ARRESTOR 
The surge arrestor (sometimes referred to as a Lightning Protector) can protect your sensitive outdoor router 
equipment from high-voltage surges caused by discharges and transients at the antenna. 
Figure 7. Surge Arrestor 
To mount the surge arrestor: 
1.  Determine a suitable location for the bracket (item b) as described in “Chapter 1. Preparing for 
Installation” on page 8. 
2.  Use the screws (item c) to attach the bracket to the wall. 
3.  Apply a ring-terminal to the ground wire. Use the bolt, lock-washer, and nut (item d) to connect the 
ground wire (item e) to the mounting bracket. 
4.  The ring-terminal and ground wire are not included, but must be installed by a certified electrician familiar 
with national electricity and safety codes, according to the instructions described in “Grounding System” 
on page 16. 
5.  Insert the surge arrestor (item a) into the bracket as depicted in the preceding figure.
