Safety Notices
WARNING
WARNING
The following general safety precautions must be observed during all phases of
operation of this instrument. Failure to comply with these precautions or with
specific warnings or instructions elsewhere in this manual violates safety
standards of design, manufacture, and intended use of the instrument. Keysight
Technologies assumes no liability of the customer’s failure to comply with the
requirements.
The equipment is for industrial use. Equipment operators are subject to all
applicable safety regulations. Along with the warning and safety notices in this
manual, all relevant safety, accident prevention, and environmental regulations
must also be followed. In particular, the operators of the equipment:
– Must be informed of the relevant safety requirements.
– Must have read and understood the operating manual before using the
– Must use the designated and recommended safety equipment.
General
Do not use this product in any manner not specified by the manufacturer.
The protective features of this product may be impaired if it is used in a
manner not specified in the operating instructions.

Environmental conditions
Never use the instrument outside of the specified environmental conditions
described in the Environmental Characteristics of the RP7900 Series
Operating and Service Guide.
WARNING
Heavy weight
WARNING
WARNING
Danger to hands and feet. To avoid personal injury and damage to the
instrument, always use a sturdy cart or other suitable device to move the
instrument. Do not lift the instrument alone; always use two people to lift
the instrument.
SHOCK HAZARD - Ground the instrument
This product is provided with a protective earth terminal. To minimize shock
hazard, the instrument must be connected to the AC mains through a
grounded power cable, with the ground wire firmly connected to an
electrical ground (safety ground) at the power outlet. Any interruption of the
protective (grounding) conductor or disconnection of the protective earth
terminal will cause a potential shock hazard that could result in injury or
death.
Before applying power
Verify that all safety precautions are taken. All connections must be made
with the unit turned off, and must be performed by qualified personnel who
are aware of the hazards involved. Improper actions can cause fatal injury as
well as equipment damage. Note the instrument's external markings
described under Safety Symbols and Regulatory Markings.

WARNING
SHOCK HAZARD, LETHAL VOLTAGES
WARNING
WARNING
WARNING
WARNING
Many models generate voltages greater than 60 VDC, with some models
rated at 950 VDC! Ensure that all instrument connections, load wiring, and
load connections are either insulated or covered using the safety covers
provided, so that no accidental contact with lethal voltages can occur.
SHOCK HAZARD
Never touch cables or connections immediately after turning off the unit.
Depending on the model, lethal voltages can remain at the output terminals
for several seconds after turn-off. Verify that there is no dangerous voltage
on the output or sense terminals before touching them.
SHOCK HAZARD from external energy sources
Because the instrument can be used as a load to sink current, hazardous
voltages from an external energy source such as a battery may be present on
the output terminals even with the unit turned off. Provision must be made
to disconnect the external energy source before touching the output or
sense terminals.

Do not operate in an explosive atmosphere
Do not operate the instrument in the presence of flammable gases or fumes.
Do not remove the instrument cover
Only qualified, service-trained personnel who are aware of the hazards
involved should remove instrument covers. Always d isconnect the power
cable and any external circuits before removing the instrument cover.
WARNING
Do not modify the instrument
WARNING
WARNING
WARNING
Do not install substitute parts or perform any unauthorized modification to
the product. Return the product to a Keysight Sales and Service Office for
service and repair to ensure that safety features are maintained.
Fuses
The instrument contains an internal fuse, which is not customer accessible.
Cleaning
To prevent electric shock, always disconnect the AC mains before cleaning.
Use a dry cloth or one slightly dampened with water to clean the external
case parts. Do not use detergent or chemical solvents. Do not attempt to
clean internally.
In case of damage
Instruments that are not functioning correctly, appear damaged or defective
should be made inoperative and secured against unintended operation until
they can be repaired by qualified service personnel.

Before, During, and After Troubleshooting
1 Before turning on the unit under test (UUT):
– Make sure all connections are done correctly.
– Connect the 3-phase power cord to the UUT before connecting the plug to
3-phase main power trunk.
2During test:
– DO NOT probe any area of the UUT as there is HIGH RAIL VOLTAGE present
while the UUT is powered ON.
– If you wish to measure any test points, always ensure that the DMM probes
stay on the measurement area before powering on the UUT.
3 After test:
– Turn off the UUT and all other testing equipment.
– Unplug the 3-phase power cord immediately.
– DO NOT touch any location of the UUT as the HIGH RAIL VOLTAGE is slowly
discharging (the RAIL LED is RED).
– Wait 5 minutes or until the RAIL LED is OFF before performing any
disassembly procedure.

preserve rail charge in the event of a line fault.
3-phase AC/DC front end:
The 3-phase AC/DC front end consists of the Power Factor Correction (PFC)
bias-control board, PFC driver board, and PFC inverter board. Its main function is
to convert the 3-phase AC input voltage to the require DC voltage as shown in
table below.
The AC front end will assert a PF signal to the secondary FPGA when the line
conditions are severe enough that the output power should be restricted or if the
rail voltage dips below a ‘power fault’ level. The purpose of this signal is to quickly
notify the regulation board to temporarily latch its output in the event of a brief
line drop out.

PFC inverter board operation
– The inverter boards consists of fuses, relay, big relay, and hall current sensors.
– The AC 3-phase input will go through the fuses. By turning on the bias, the AC
input will go through a small relay with a resistor path in order to have a soft
charge on the capacitor in the driver board. After that, the big relay will be
turned on when you hear the second clicking sound.
– The current passes through the hall sensor into the choke followed by the IGBT
and output capacitors.
PFC driver board operation
– The PFC driver boards consists of photo-detectors and big capacitors. The
gate driver output is influenced by signals from the photo-detector circuitry.
During normal operation, if the supply voltage is above the UVLO threshold,
the output of the photo-detector will drive the IGBTs of the output stage.

Isolation and isolation attic board operation
– The isolation board consists of a H bridge circuitry that can step up and step
down the voltage to the required voltage level. Its main function is to provide
the isolation between the primary and secondary circuits. It receives the DC
voltage from the AC front end and then adjusts the voltage level to 565 V. The
isolation attic board consist of a transformer and over-current protection
circuitry.
– The isolation board protects itself from ‘live’ conditions, such as local over
temperature (OT) and rail over voltage (OV) or low voltage (LV). The source of
a rail OV/LV will either be an issue with its input, an internal malfunction, or a
regulation board malfunction.

Bias board operation
– The bias board is made of a half-bridge LLC with two flying shielded
transformers.
– It receives the PG signal and outputs voltage (425 V or 980 V) from the AC
front end, steps down the voltage, and provides the bias voltages to the
respective modules.
– It communicates using the PG signal from the front-end.
