No voltage selection is required, since the instrument automatically
adapts to the line voltage present.
Fuses
The power supply of the LSA1000 is protected against short-circuit
and overload by me
ans of two 5x20mm“T”-rated 5 amp, 250 V AC
fuses, located above the mains plug on the rear panel.
Disconnect the power cord before inspecting or replacing a fuse.
Open the fuse box by inserting a small screwdriver under the plastic
cover and prying it open.
WARNING
For continued fire protection at all line voltages, replace only
with fuses of the specified type and rating (see above).
For continued fire protection at all line voltages, replace only with
fuses of the specified type and rating (
see above).
Ground
The LSA1000 has been designed to operate from a single-phase
power source, with one of the current-carrying conductors (neutral
conductor) at ground (earth) potential. Maintain the ground line to
avoid an electric shock.
None of the current-carrying conductors may exceed 250 V rms with
respect to ground potential. The LSA1000 is provided with a three-
wire electrical cord containing a three-terminal polarized plug for
mains voltage and safety ground connection. The plug's ground
terminal is connected directly to the frame of the unit. For adequate
protection against electrical hazard, this plug must be inserted into a
mating outlet containing a safety ground contact.
Cleaning and Maintenance
Maintenance and repairs should be carried out exclusively by a
LeCroy technician (
see Chapter 1 ). Cleaning should be limited to the
exterior of the instrument only, using a damp, soft cloth. Do not use
chemicals or abrasive elements. Under no circumstances should
moisture be allowed to penetrate the instrument. To avoid electric
shocks, disconnect the instrument from the power supply before
cleaning.
CAUTION
Electric shock hazard: To avoid personal injury, do not
remove covers. No user-serviceable parts inside. Leave
repair to qualified personnel.
Power On
Connect the instrument to the power outlet and switch it on using the
main On/Off switch, located on the rear panel followed by the
