1.3 Measurement Category
Measurement Category
This instrument can make measurements in Measurement Category I.
WARNING
This instrument can only be used for measurements within its specified measurement
categories.
Measurement Category Definitions
• Measurement category I is for measurements performed on circuits not directly
connected to MAINS. Examples are measurements on circuits not derived from
MAINS, and specially protected (internal) MAINS derived circuits. In the latter
case, transient stresses are variable. Thus, you must know the transient withstand
capability of the equipment.
• Measurement category II is for measurements performed on circuits directly
connected to low voltage installation. Examples are measurements on household
appliances, portable tools and similar equipment.
• Measurement category III is for measurements performed in the building
installation. Examples are measurements on distribution boards, circuit-breakers,
wiring (including cables, bus-bars, junction boxes, switches and socket-outlets) in
the fixed installation, and equipment for industrial use and some other
Safety Requirement

equipment. For example, stationary motors with permanent connection to a
fixed installation.
• Measurement category IV is for measurements performed at the source of a
low-voltage installation. Examples are electricity meters and measurements on
primary overcurrent protection devices and ripple control units.
1.4 Ventilation Requirement
This instrument uses a fan to force cooling. Please make sure that the air inlet and
outlet areas are free from obstructions and have free air. When using the instrument
in a bench-top or rack setting, provide at least 10 cm clearance beside, above and
behind the instrument for adequate ventilation.
CAUTION
Inadequate ventilation may cause an increase of temperature in the instrument, which
would cause damage to the instrument. So please keep the instrument well ventilated and
inspect the air outlet and the fan regularly.

Protection Level Against Electric Shock
ESD ±8kV
Installation (Overvoltage) Category
This product is powered by mains conforming to installation (overvoltage) category II.
WARNING
Ensure that no overvoltage (such as that caused by a bolt of lightning) can reach the
product. Otherwise, the operator might be exposed to the danger of an electric shock.
Installation (Overvoltage) Category Definitions
Installation (overvoltage) category I refers to signal level which is applicable to
equipment measurement terminals connected to the source circuit. Among these
terminals, precautions are done to limit the transient voltage to a low level.
Installation (overvoltage) category II refers to the local power distribution level which
is applicable to equipment connected to the AC line (AC power).
Pollution Degree
Pollution Degree 2
Pollution Degree Definition
• Pollution Degree 1: No pollution or only dry, nonconductive pollution occurs.
The pollution has no effect. For example, a clean room or air-conditioned office
environment.
• Pollution Degree 2: Normally only nonconductive pollution occurs. Temporary
conductivity caused by condensation is to be expected. For example, indoor
environment.
• Pollution Degree 3: Conductive pollution or dry nonconductive pollution that
becomes conductive due to condensation occurs. To be found in industrial
environment or construction sites (harsh environments). For example, sheltered
outdoor environment.
• Pollution Degree 4: The pollution generates persistent conductivity caused by
conductive dust, rain, or snow. For example, outdoor areas.

5To Prepare for Use
5.1 Connecting to Power
DP2000 series power supply supports various AC power inputs. The AC selector
setting on the rear panel differs when input power is different, as shown in the table
below.
Table 5.1 AC input power specifications (including AC selector setting)
AC input power AC selector
100 Vac±10%, 50 Hz to 60 Hz 100
120 Vac±10%, 50 Hz to 60 Hz 120
220 Vac±10%, 50 Hz to 60 Hz 220
230 Vac±10% (Max. 250 Vac), 50 Hz to 60 Hz 230
Please connect the power strictly following the steps below.
1. Check the Input Power
Please make sure that the input AC power fulfills the requirements in
Table 5.1 AC
input power specifications (including AC selector setting) .
2. Check the AC Voltage Selector on the Rear Panel
Please make sure that the AC voltage selector (100, 120, 220, or 230) on the rear
panel is set to match the actual input voltage. To change the input AC voltage
selector on the power supply, use the two AC selector switches on the rear panel of
the power supply as shown below.
Please set the switches following the diagram above. For example, to select 100 V,
slide both switches to the left; to select 220 V, slide the upper switch to the left and
the lower switch to the right.
To Prepare for Use
16 Copyright ©RIGOL TECHNOLOGIES CO., LTD. All rights reserved.

3. Check the Fuse
The instrument has been equipped with the specified fuse when it leaves factory.
Please make sure that the fuse matches the actual input voltage by referring to
“Input power requirement” or
Replacing the Fuse .
4. Connect to AC Power
Please connect the instrument to AC power using the power cord provided in the
accessories.
WARNING
To avoid electric shock, please make sure that the instrument is correctly grounded.
5.2 Power-on Inspection
Press the power key on the front panel to switch on the instrument. During the start-
up process, the instrument performs a series of self-tests. If the instrument passes the
self-test, the welcome interface will be displayed; otherwise, the corresponding self-
test failure information will be displayed.
TIP
If you want to power on the instrument again after powering it off, please make sure that the
time interval between the two power-on operations is greater than 5 s.
5.3 Connecting the Outputs
This series power supply is equipped with front and rear output terminals. This
section describes how to make front and rear connections.
Front Outputs Connections
Method 1: Connect wires to the front of the terminals as shown in (A).
To Prepare for Use
Copyright ©RIGOL TECHNOLOGIES CO., LTD. All rights reserved. 17

Method 2: Rotate the terminal block screws counter-clockwise and connect wires to
the terminals in location (B). Then rotate the screws clockwise to tighten the wires.
This method can help avoid errors caused by the terminal resistance.
CAUTION
Turn off AC power before making front panel connections. All wires and straps must be
properly connected to prevent currents from damaging the loads.
Rear Outputs Connections
Insert the connector plug into the rear terminal. Secure the connector by tightening
the locking screws.
CAUTION
Turn off AC power before making rear panel connections. All wires and straps must be
properly connected to prevent currents from damaging the loads.
TIP
Do not use both front and rear panel output terminals concurrently.
5.4 Replacing the Fuse
The fuse rating required depends on the instrument model and actual input voltage,
as shown in the table below. You can also refer to Table 5.1 AC input power
specifications (including AC selector setting) .
