Ground the Instrument
To avoid electric shock, the instrument chassis and cabinet must be
grounded with the supplied power cable's grounding prong.
Do NOT Operate in an Explosive Atmosphere

disconnect the power and discharge circuits before touching them.

To avoid the danger of introducing additional hazards, do not install
substitute parts or perform unauthorized modifications to the instrument.
