WA1K2K-OM-E RevB 5

 Installation (Overvoltage) Categories II (Mains Supply Connector)

& I (Measuring Terminals).

 Pollution Degree 2.
 Protection Class I.

PLEASE NOTE THE FOLLOWING:

 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. Conductivity
caused by temporary condensation should 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 ground conductor
in the building wiring.

Cooling

The instrument relies on forced air cooling with an internal fan and
ventilation openings. Care must be taken to avoid restricting the airflow
around the apertures (fan holes) at the sides of the oscilloscope. Ensure
adequate ventilation by leaving the required 5 cm (2 inch) minimum gap
around the sides of the instrument.

CAUTION

Do not block the ventilation holes located on both sides of the
oscilloscope.

CAUTION

Do not allow any foreign matter to enter the oscilloscope through the
ventilation holes, etc.

AC Power Source

100 to 240 VAC (±10%) at 50/60/400 Hz (+10%); Installation Category:
300V CAT II

No manual voltage selection is required because the instrument
automatically adapts to line voltage.

Power Consumption

< 50 Watts for all models (depending on accessories installed - probes,
USB devices, etc.).

Power consumption in Standby Mode: < 5 Watts.

Power and Ground Connections

The instrument is provided with a 10A/250V 18AWG rated grounded
cord set containing a molded three-terminal polarized plug and a
standard IEC-60320 (Type C13) connector for making line voltage and
safety ground connections. The AC inlet ground terminal is connected
directly to the frame of the instrument. For adequate protection against
electrical shock hazard, the power cord plug must be inserted into a
mating AC outlet containing a safety ground contact.

WARNING - Electrical Shock Hazard

Only use the power cord provided with your instrument.

Any interruption of the protective conductor inside or outside of the
oscilloscope, or disconnection of the safety ground terminal creates a
hazardous situation. Intentional interruption is prohibited.

In Standby mode, the oscilloscope is still connected to the AC supply. The
instrument can only be placed in a complete Power Off state by flipping
the main power switch on the rear of the instrument (if provided) to the
off (Zero) position or by removing the power cord. In cases where no
main power switch is provided, removing the main power cord is the
disconnect device.
