Hi Randy,

Grounding the case to mains ground is for safety. All equipment with direct 
feeds should have their case connected to mains ground (this includes the 
transformer). In the event of a fault, we don't want the case at a 
potential that could be lethal. Should there be a fault, the mains breaker 
will trip and remove all power.

Take care,
Bart
