Best practice in making a ground connection from Ed are to insure a non resistive connection to a known and tested ground in
a well built electrical installation or connect the ground lug of PC to a metallic water pipe going to earth or to a rod deeply
planted to earth.
Connection to ground should be verified regularly. If connection to ground is not well established and maintained, electrical
surge protection of phone lines is absent.
Alternative for ground posts directly on Ed are: pin 1 or relay connector J10 or mounting hols at the far right (when look at board
top component side). Consult MCDI prior to using mounting holes as ground post.
