General Safety Considerations
WARNING
The instructions in this document are for use by qualied personnel
only.To avoid electrical shock, do not perform any servicing unless you
are qualied to do so.
The opening of covers or removal of parts is likely to expose dangerous
voltages. Disconnect the instrument from all voltage sources while it is
being opened.
The power cord is connected to internal capacitors that may remain live
for ve seconds after disconnecting the plug from its power supply.
This is a Safety Class 1 Product (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.
For continued protection against re hazard, replace fuse only with
same type and ratings, (type nA/nV). The use of other fuses or materials
is prohibited.
W
ARNING
Before this instrument is switched on, make sure it has been properly
grounded through the protective conductor of the ac power cable to a
socket outlet provided with protective earth contact.
Any interruption of the protective (grounding) conductor, inside
or outside the instrument, or disconnection of the protective earth
terminal can result in personal injury
.
Before this instrument is switched on, make sure its primary power
circuitry has been adapted to the voltage of the ac power source
.
F
ailure to set the ac power input to the correct voltage could cause
damage to the instrument when the ac power cable is plugged in.
