Safety Requirement

1.1 General Safety Summary

Please review the following safety precautions carefully before putting the instrument into operation so as to avoid any personal injury or damage to the instrument and any product connected to it. To prevent potential hazards, please follow the instructions specified in this manual to use the instrument properly.

• Use Proper Power Cord.

Only the exclusive power cord designed for the instrument and authorized for use within the destination country could be used.

• Ground the Instrument.

The instrument is grounded through the Protective Earth lead of the power cord. To avoid electric shock, it is essential to connect the earth terminal of the power cord to the Protective Earth terminal before connecting any inputs or outputs.

• Observe All Terminal Ratings.

To avoid fire or shock hazard, observe all ratings and markers on the instrument and check your manual for more information about ratings before connecting the instrument.

• Use Proper Overvoltage Protection.

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.

• Do Not Operate Without Covers.

Do not operate the instrument with covers or panels removed.

• Do Not Insert Objects Into the Air Outlet.

Do not insert objects into the air outlet, as doing so may cause damage to the instrument.

• Use the Proper Fuse.

Please use the specified fuses.

• Avoid circuit or wire exposure.

Do not touch exposed junctions and components when the instrument is powered on.

• Do Not Operate With Suspected Failures.

If you suspect damage occurs to the instrument, have it inspected by RIGOL authorized personnel before further operations. Any maintenance, adjustment or

DP900 User Guide

Safety Requirement

• Keep Well Ventilation.

• Do Not Operate in Wet Conditions.

• Do Not Operate in an Explosive Atmosphere.

• Keep Instrument Surfaces Clean and Dry.

replacement especially to circuits or accessories must be performed by RIGOL authorized personnel.

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.

To avoid short circuit inside the instrument or electric shock, never operate the instrument in a humid environment.

To avoid personal injuries or damage to the instrument, never operate the instrument in an explosive atmosphere.

To avoid dust or moisture from affecting the performance of the instrument, keep the surfaces of the instrument clean and dry.

• Prevent Electrostatic Impact.

Operate the instrument in an electrostatic discharge protective environment to avoid damage induced by static discharges. Always ground both the internal and external conductors of cables to release static before making connections.

• Use the Battery Properly.

Do not expose the battery (if available) to high temperature or fire. Keep it out of the reach of children. Improper change of a battery (lithium battery) may cause an explosion. Use the RIGOL specified battery only.

• Handle with Caution.

Please handle with care during transportation to avoid damage to keys, knobs, interfaces, and other parts on the panels.

• Do not use this instrument to provide power for the active load.

The backflow current may cause the power control loop to be out of control, which could further damage the devices that receives the power supply from this instrument. Therefore, this instrument is only allowed to provide power for the pure load that does not have the current output function.

1. Check the Input Power

Quick Start

Please make sure that the input AC power fulfills the requirements in

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.

Table 4.3 AC

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

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.

4.7 Power-on Inspection

Press the power key on the front panel to switch on the instrument. During the startup 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 selftest 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.

4.8 Connecting the Outputs

This series power supply provides three-channel outputs, which share the same connection method. Please follow the instructions below to connect the outputs.

Method 1: Connect wires to the front of the terminals as shown in (A).

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.

TIP

As the output terminals of DP932U are safety sockets, “Method 2” is not supported.

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.

4.9 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

specifications (including AC selector setting)
