Ground the instrument
To minimize shock hazard, the equipment chassis and enclosure must be
connected to an electrical ground. If the equipment is supplied with a
three-conductor ac power cable, the power cable must be either plugged
into an approved three-contact electrical outlet or used with a
three-contact to two-contact adapter. The three-contact to two-contact
adapter must have the grounding wire (green) firmly connected to an
electrical ground (safety ground) at the power outlet. The power jack and
mating plug of the power cable must meet International Electrotechnical
Commission (IEC) safety standards.
