Make sure all the shields are in place, it's in a metal cabinet, and
*MAKE SURE* you have *good* grounds on the whole thing! Don't rely on
the ground on the AC line cord. Find a ground rod, or if you're on a
building roof, at least a water pipe, like the sprinker pipe (NOT the
head!). Use the same ground as the lighting arrestors, ie, run a large
(>8 Ga.) wire from the cabinet rail (not just the cabinet) to the point
where the ground attaches to the arrestor.
