ATTENTION: You are strongly advised to read this chapter thoroughly before
installing your oscilloscope.
2.1 SAFETY INSTRUCTIONS
2.1.1 EARTHING (GROUNDING)
Before any connection to the inputs is made, the instrument must be connected
to protective earth (ground) via the three-core mains (line) cable. The mains
(line) plug must be inserted only into a socket outlet provided with a protective
earth (ground) contact. The protective action must not be negated by the use of
an extension cord without protective conductor.
WARNING: Any Interruption ot the protective conductor Inside or outside
the instrument is likely to make the Instrument dangerous.
Intentional Interruption Is prohibited.
When an instrument is brought from a cold into a warm environment,
condensation may cause a hazardous condition. Therefore, make sure that the
earthing (grounding) requirements are strictly adhered to.
2.1.2 MAINS (LINE) VOLTAGE CORD AND FUSES
Different power cords are available for the various local mains (line) voltage
outlets. The power cord version delivered is determined by the particular
instrument version ordered.
NOTE: If the mains (line) plug has to be adapted to the local situation,
such adaptation should be done only by a qualified technician.
This oscilloscope has a tapless switched-mode power supply that covers most
nominal voltage ranges in use:
AC voltages from 100 V-..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.
WARNING: The Instrument shall be disconnected from all voltage sources
when renewing a fuse.
Mains (line) fuse rating: 1,6 AT delayed-action, 250 V
(for ordering code, see page i).
