General Safety Considerations
WARNING
The instructions in this document are for use by qualified personnel
only.Toavoid electrical shock, do not perform any servicing unless
you are qualified 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 five 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 lik
ely to mak
ethe instrument dangerous.
Intentional interruption is prohibited.
For continued protection against fire 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, mak
esure it has been
properly grounded through the protectiv
econductor of the ac po
w
er
cable to asock
et outlet pro
vided with protectiv
eearthcontact.
Any interruption of the protectiv
e(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.
Failure to set the ac power input to the correct voltage could cause
damage to the instrument when the ac power cable is plugged in.
