4.2 Grounding Protection
Electronic circuits are susceptible to voltage surges. The iSIC has on-board transient voltage
suppression devices. Connect the ground lug to a proper electrical ground (i.e. earth ground or a
properly grounded pipe/metal fixture).
For outdoor applications, use the copper wire supplied with the A38 ground kit to connect the
ground lug to the rod‟s ground clamp. The rod should be driven into the ground as deep as
possible and located near the equipment. In addition, make sure the copper wire has no sharp
bends and is as short as possible. Be sure to locate the clamp on the rod before driving it with a
sledgehammer or fence post driver.
