Before plugging in the power cable, make sure that the instrument is suitable for the
correct line voltage.
Note
When the mains plug has to be adapted to the local situation, such
adaptation should be done by a qualified technician only.
The instrument has a switched-mode mains power supply that covers most nominal
voltage ranges in use: ac voltages from 100 to 240 V (r.m.s.). This obviates the need to
adapt to the local line voltage. The nominal line frequency is 50 to 60 Hz.
Warning
The instrument shall be disconnected from all voltage sources
when a fuse is to be renewed.
The fuses are located in a fuse holder of the input power module at the rear panel. When
the line fuses need replacing, proceed as follows:
•
disconnect the power cable from the power module.
•
press the clip of the fuseholder and pull out the holder, see illustration.
•
fit new fuses of the correct rating (according to IEC127 T1.6A or CSA/UL 198G
T1.6A) and refit the fuseholder.
Warning
To avoid fire hazards, make sure the instrument fuses are of
the type and current rating specified. Do not use repaired fuses
and/or short-circuited fuseholders. Do not defeat this important
safety feature.
