8 ISSUED: September 2005 WE-GS-E Rev A
Note:
The design of the scope has been verified to conform to
EN 61010-1 safety standard per the following limits:
Installation (Overvoltage) Categories II (Mains Supply
Connector) & I (Measuring Terminals)
Pollution Degree 2
Protection Class I
Installation (Overvoltage) Category II refers to
local distribution level, which is applicable for
equipment connected to the mains supply (AC
power source).
Installation (Overvoltage) Category I refers to
signal level, which is applicable for 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 grounded
equipment, in which protection against electric
shock is achieved by Basic Insulation and by
means of a connection to the protective
earthing conductor in the building wiring.
Cooling
CAUTION
Do not block the ventilation holes located on
both sides and rear of the scope.
The scope 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.
CAUTION
Do not allow any foreign matter to enter the
scope through the ventilation holes, etc.
