Ground the MPS using the provided ground wire. If you anticipate heavy 
surges, you may wish to use a heavier wire or multiple wires. Cut the ground 
wire to the length required to reach from the MPS to a suitable ground, such as 
Davis Instruments’ Grounding Kit (Product #7780). The ground wire should be 
as short as possible. Strip both ends of the ground wire (remove the spade lug 
if necessary) and insert one end into the ground lug. Secure in place by tighten-
ing the ground lug screw. Attach the other end to a suitable ground.
