1.
It's efficient to install within 5m from power switchboard of the facilities to protect from lightning strike, surge etc and 10m from protecting facilities
2.
Turn-off power breaker of eca3G, turn-off main breaker of switchboard and connect main breaker and eca3G ( cable standard : 4mm2 - 10mm2, cable length : within 5m )
3.
Connect grounding cable to grounding terminal of facility to protect and connect to grounding cable connecting bolt of eca3G.
(* connection cable standard : over 4mm2, length : within 10m recommended)
4.
In case grounding of protecting facility is connected to MGB ( Main Ground Board ) , connect grounding to eca3G and connect to MGB firmly that grounding of protected facility is connected.
5.
Connect coaxial cable of CCTV facility to coaxial cable 1st(in), 2nd(out)terminal of eca3G.
6.
If lightning rod is installed, connect grounding cable of more than 35mm2 to grounding cable which is connected to lightning reduction cable so that make electric connection better to MGB of eca3G ( grounding cable standard : over 35mm2 )
7. Turn-on main breaker of switchboard and power breaker switch of eca3G.
