SDA Operator’s Manual
Power Consumption
SDA 6020, 4020, 9000, 11000, 13000, 18000: 800 watts
(800 VA) depending on accessories installed (internal printer,
probes, PC port plug-ins, etc.)
SDA 4000A, 5000A, 6000A: 650 watts (650 VA)
The power supply of the scope is protected against
short circuit and overload by a 5x20 mm fuse (T10.0
A/250 V). See “Fuse Replacement” section for
replacement instructions.
Power and Ground Connections
The instrument is provided with a grounded cord set
containing a molded three-terminal polarized plug and a
standard IEC320 (Type C13) connector for making line
voltage and safety ground connection. 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!
Any interruption of the protective
conductor inside or outside of the
scope, or disconnection of the safety
ground terminal creates a hazardous
situation.
Intentional interruption is prohibited.
In Standby mode the scope is still connected to the AC
supply. The instrument can only be placed in a complete
Power Off state by physically disconnecting the power
cord from the AC supply.
The scope should be positioned to allow easy access to
the socket-outlet. To disconnect the scope from the AC
supply, unplug the instrument’s power cord from the AC
outlet after the scope is placed in Standby state.
See “Standby (Power) Switch and Scope Operational
States” section for more information.
CAUTION
The outer shells of the front panel
terminals (CH1, CH2, CH3, CH4, AUX
IN, AUX OUT) are connected to the
instrument’s chassis and therefore
to the safety ground.
