Cooling; Ac Power Source - LeCroy WaveMaster 8600A Operator's Manual

Installation (Overvoltage) Category II refers to local
distribution level, which is applicable to equipment
connected to the mains supply (AC power source).
Installation (Overvoltage) Category I refers to signal
level, which is applicable to equipment measuring
terminals that are connected to source circuits in which
measures are taken to limit transient voltages to an
appropriately low level.
Pollution Degree 2 refers to an operating environment
where normally only dry non-conductive pollution
occurs. Occasionally a temporary conductivity caused
by condensation must be expected.
Protection Class 1 refers to a grounded equipment, in
which protection against electric shock is achieved by
Basic Insulation and by means of a connection to the
protective ground conductor in the building wiring.

Cooling

The instrument relies on forced air cooling with internal
fans and ventilation openings. Care must be taken to
avoid restricting the airflow around the apertures (fan
holes) at the sides and rear of the scope. To ensure
adequate ventilation it is required to leave a 10 cm (4
inch) minimum gap around the sides and rear of the
instrument.
The instrument also has internal fan control circuitry that
regulates the fan speed based on the ambient
temperature. This is performed automatically after
start-up with no manual intervention required.

AC Power Source

100 to 240 Vrms (+/-10%) AC at 50/60 Hz; 115 Vrms
(+/-10%) AC at 400 Hz; Automatic AC voltage selection;
Installation Category: 300V CAT II
No manual voltage selection is required because the
instrument automatically adapts to line voltage.
