To protect users, the metal instrument panels and cabinet are grounded
through the three-conductor power line cord in accordance with International
Electrotechnical Commission (IEC) requirements.
The three-conductor power line cord, when plugged into a properly grounded
receptacle, grounds the instrument and minimizes shock hazard. A properly
grounded receptacle is one that is connected to a suitable earth ground. Be
sure to verify proper receptacle grounding. The GC requires an isolated
ground.
Connect the GC to a dedicated circuit.
