2 INSTALLATION INSTRUCTIONS
Attention: You are strongly advised to read this chapter thoroughly before
installing your oscilloscope.
2.1 SAFETY INSTRUCTIONS
2.1.1 Protective earthing
Before any connection to the input connectors is made, the instrument shall be
connected to a protective earth conductor via the three-core mains cable; the
mains plug shall be inserted only into a socket outlet provided with a protective
earth contact. The protective action shall not be negated by the use of an
extension cord without protective conductor.
WARNING: Any interruption of the protective conductor inside or outside
the instrument is likely to make the instrument dangerous.
Intentional interruption is prohibited.
WARNING: When an instrument is brought from a cold into a warm
environment, condensation may cause a hazardous
condition. Therefore, make sure that the grounding
requirements are strictly adhered to.
2.1.2 Mains voltage cord, mains voltage range and fuses
Before inserting the mains plug into the mains socket, make sure that the
instrument is suitable for the local mains voltage.
NOTE: When the mains plug has to be adapted to the local situation, such
adaption should be done by a qualified technician only.
WARNING: The instrument shall be disconnected from all voltage
sources when a fuse is to be renewed.
The oscilloscope has a tapless switched-mode power supply that covers most
nominal voltage ranges in use: ac voltages from 100 ... 240 V (r.m.s.). This
obviates the need to adapt to the local mains (line) voltage. The nominal mains
(line) frequency range is 50 Hz ... 400 Hz.
Line fuse rating: 3.15 AT delayed action, 250 V (for ordering code see
"INITIAL INSPECTION").
