working with AC supply voltage. See also
Suitable MC cable sockets for connecting cables are included in the equipment sup-
plied.
1. Make sure that the connected mains supply is sufficiently fused for the maximum
permissible continuous current voltage of the R&S
ENV4200 as listed in the data
sheet.

DANGER!
Risk of electric shock. Make sure that the R&S
ENV4200 is connected
to the protective ground terminal before you connect the R&S

power source. The protective ground connection must remain until you have dis-
connected the R&S
ENV4200 from the power supply.
