Kijanki,
For the best possible protection the SPD (Surge Protection Device) should be installed in 2 spaces nearest the main breaker or in the case of a main lug only panel the SPD unit should be installed in 2 spaces nearest the panel feed wires that connect to the electrical panel.
It is very important that your main electrical service grounding electrode system is installed and wired correctly. All connections should be mechanically tight and connections are not corroded. Going from memory, IEEE/ANSI recommends a 5 ohm or less soil resistance for a proper/good earth grounding electrode system. Your SPD is only as good as the grounding electrode system resistivity/conductivity connection to mother earth.
Make 100% sure any/all CATV, TV antenna, satellite dish, and phone incoming cables/lines that enter your home from outside are properly grounded, connected, to the main grounding electrode system of the main electrical service of your home. This is a must when dealing with a near by lightning strike.
