Grounding
Caution A proper earth ground is required for GC operations.
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.
Proper receptacle grounding should be verified.
Make sure the GC is connected to a dedicated receptacle. Use of a dedicator
receptacle reduces interference.
Caution Any interruption of the grounding conductor or disconnection of the power
cord could cause a shock that could result in personal injury.
Line voltage
The GC operates from one of the AC voltage supplies listed in Table 530-1,
depending on the standard voltage of the country from which it was ordered.
GCs are designed to work with a specific voltage; make sure your GC voltage
option is appropriate for your lab. The voltage requirements for your GC are
printed near the power cord attachment.
