Connecting to the Power Supply
This is a Safety Class I instrument (provided with a protective
earthing ground, incorporated in the power cord). The mains plug
shall only be inserted in a socket outlet provided with a protective
earth contact. Any interruption of the protective conductor inside or
outside of the instrument is likely to make the instrument dangerous.
Intentional interruption is prohibited.
The mains switch fitted to the instrument is a single pole device and
must not be used as the disconnect device. An IEC320 coupler
(mains input power cord) is intended as the main disconnect device.
The switch is marked I and 0. The I indicates on and the O indicates
off. Do not position the instrument such that access to the coupler is
impaired.
Before switching on this instrument, make sure that the line supply
voltage is in the specified ranges. Mains supply voltage fluctuations
should not exceed +/- 10% of the nominal line voltage. Range
selection is automatic.
