High voltage is present inside this instrument. To avoid electric-shock hazard,
operating personnel must not remove the protective cover. Do not disconnect the Earth connection. Any
interruption of the grounding connection can create an electric shock hazard. Before making external
connections, always ground the B42 first by connecting the control panel to ground.
