Each chassis in the system must be grounded separately using the procedure listed below.
1. Loosen the screw.
2. Insert a grounding wire (user supplied).
3. Tighten the screw.
4. Connect the grounding wire to earth ground.
Proper grounding is very important to protect the system from external
noise and to reduce the risk of electrocution in the event of a lightning
strike.
