1.7 Safety
1.7.1 Safety notices
Mortal danger - Hazardous voltage
• Electrical equipment operation means that some parts can be under dangerous voltage.
Therefore all parts under voltage must be covered! This basically applies to all models,
though 40 V models according to SELV can’t generate hazardous DC voltage.
• All work on connections must be carried out under zero voltage (output not connected
to load) and may only be performed by qualied and informed persons. Improper ac-
tions can cause fatal injury as well as serious material damage.
• Never touch cables or connectors directly after unplugging from mains supply as the
danger of electric shock remains!
• Never touch the contacts on DC output terminal directly after switching o󰀨 the DC output,
because there still can dangerous voltage present, sinking more or less slowly depend-
ing on the load! There also can be dangerous potential between negative DC output to
PE or positive DC output to PE due to charged X capacitors, which don’t discharge at
all or only very slowly.
• Always follow 5 safety rules when working with electric devices:
• Disconnect completely
• Secure against reconnection
• Verify that the system is dead
• Carry out earthing and short-circuiting
• Provide protection from adjacent live parts
• The equipment must only be used as intended
• The equipment is only approved for use within the connection limits stated on the product label.
• Do not insert any object, particularly metallic, through the ventilator slots
• Avoid any use of liquids near the equipment. Protect the device from wet, damp and conden-
sation.
• For power supplies and battery chargers: do not connect users, particularly low resistance, to
devices under power; sparking may occur which can cause burns as well as damage to the
equipment and to the user.
• For electronic loads: do not connect power sources to equipment under power, sparking may
occur which can cause burns as well as damage to the equipment and to the source.
• ESD regulations must be applied when plugging interface cards or modules into the relative slot
• Interfacecardsormodulesmayonlybeattachedorremovedafterthedeviceisswitchedo󰀨.
It is not necessary to open the device.
• Do not connect external power sources with reversed polarity to DC input or outputs! The
equipment will be damaged.
• For power supply devices: avoid where possible connecting external power sources to the DC
output, and never those that can generate a higher voltage than the nominal voltage of the device.
• For electronic loads: do not connect a power source to the DC input which can generate a volt-
age more than 120% of the nominal input voltage of the load. The equipment is not protected
against over voltage and may be irreparably damaged.
• Never insert a network cable which is connected to Ethernet or its components into the master-
slave socket on the rear side of the device!
• Alwayscongurethevariousprotectingfeaturesagainstovercurrent,overpoweretc.forsensi-
tive loads to what the target application requires!

1.7.5 Alarm signals
Alarm conditions, not danger situations, are signalled on the front of this slave device in form of a red LED “Error”
(also see section 1.8.4.). Because the models of this series are designed to run as slave units in a master-slave
system, the master unit will indicate alarms in its own available ways. Refer to the manual of series PSI 9000 WR
3U for more information about this matter.
The LED collects all of the below listed alarm situations. If there is supervision of the slave units being used, alarms
can be decoded by querying a status from the device via any of the two USB ports.
Global meaning of alarm situation as indicated by LED “Error”:
Signal OT
(OverTemperature)
• Overheating of the device
• DCoutputwillbeswitchedo󰀨
• Non-critical
Signal OVP
(OverVoltage)
• Overvoltage shutdown of the DC output due to high voltage entering the device or gener-
ated by the device itself due to a defect
• Critical! The device and/or the load could be damaged
Signal OCP
(OverCurrent)
• Shutdown of the DC output due to excess of the preset limit
• Non-critical, protects the load from excessive current consumption
Signal OPP

PSI 9000 WR 3U Slave Series
1.9 Construction and function
1.9.1 General description
The electronic high performance power supplies of the PSI 9000 WR 3U Slave are designed to extend the power
of compatible models from series PSI 9000 WR 3U. The slave models are reduced to basic functions and will usu-
ally run in remote control from a master of a master-slave system. They can be added and connected to existing
devices of series PSI 9000 WR 3U.
By default, the devices have an USB port on the rear side which serves various purposes, such as servicing
(rmwareupdates),monitoringduringmaster-slaveoperationorevenremotecontrolwhentheunitisbeingused
in stand-alone operation.
The additional USB port on the front side is used for quick access to all the DC output related parameters and
settings.ThecongurationviathisportcanbedonewiththeincludedsoftwareEA Power Control (on USB stick)
or via any custom made control application.
Thedeviceso󰀨erasstandardthepossibilityforparallelconnectioninSharebusoperationtoachieveaconstant
current sharing, plus a genuine master-slave connection with totalling of the slave units’ values on the master unit
from PSI 9000 WR 3U series. This kind of operation allows for up to 16 units to be combined to a single system
with a total power of up to 240 kW.

PSI 9000 WR 3U Slave Series
1.9.4 The control panel (HMI)
The HMI (Human Machine Interface) consists of six coloured LEDs, a pushbutton and an USB-B port.
1.9.4.1 Status indicators (LED)
The six coloured LEDs on the front indicate various statuses of the device:
LED Colour Indicates what when lit?
Power orange / green Orange = device is in boot phase or internal error occurred
Green = device is ready for operation
Remote green Remote control by master or any of the USB ports is active. In this situation, manual
controlwithbuttonOn/O󰀨islocked.
Error red At least one unacknowledged device alarm is active. The LED can signalise all
alarms as listed in „3.6. Alarms and monitoring“.
CC yellow Constant current regulation (CC) is active. It means, if the LED is not lit it indicates
either CV, CP or CR mode. Also see „3.2. Operating modes“.
On green DC output is switched on
O󰀨 red DCoutputisswitchedo󰀨
1.9.4.2 USB port
The front USB port is easier to access than the one on the rear side and intended for quick setup of DC output
related values and settings. Doing so is only necessary and possible in these two situations:
1. The PSI 9000 WR 3U Slave shall run as stand-alone device which is not controlled by a PSI 9000 WR 3U master.
2. The PSI 9000 WR 3U shall, due to the lack of a suitable PSI 9000 WR 3U master device, be the master of
other PSI 9000 WR 3U Slave devices.
Both situations are only secondary, as the primary and normal function of a PSI 9000 WR 3U Slave is to be a slave
in a master-slave system where it is assigned all required settings and values from the master.
When running any of the above listed situations following applies to the USB port:
• Reducedinstructionsetformaster-slaveconguration,outputvalues(U,I,P,R)andprotec-
tions (OVP, OCP, OPP). For details about the instruction set see „3.5. Remote control“.
• Takingoverremotecontrolinordertochangethecongurationisonlypossiblewhiletheunit
is not online with the master, which either requires to temporarily deactivate master-slave on
themasterortoswitchthemastero󰀨
1.9.4.3 Pushbutton “On / O󰀨”
ThisbuttoncanbeusedtoswitchtheDCoutputonoro󰀨duringmanualcontrol,i.e.thedeviceisnotin
remotecontrolbyamasterorviaanyoftheUSBports(LED“Remote”=o󰀨).Oncepushedtoswitchthe
DC output on, the device would regulate the output to the last values it has stored. Since all the output
related values are not displayed, operating that button has to be done with caution.
1.9.5 USB port type B (rear side)
The USB-B port on the rear side of the device is provided for communication with the device,
i.e. monitoring during master-slave operation or full remote control in stand-alone operation,
aswellasforrmwareupdates.TheincludedUSBcablecanbeusedtoconnectthedevice
to a PC (USB 2.0 or 3.0). The driver is delivered with the device and installs a virtual COM
port. Details for remote control can be found on the web site of the manufacturer or on the
included USB stick.
The device can be addressed via this port either using the international standard ModBus RTU
protocol or by SCPI language. The device recognises the message protocol automatically.
This USB port has no priority over either the other USB port on the front or remote control
from a master unit and can, therefore, only be used for remote control alternatively to these.
However, monitoring is always available.

PSI 9000 WR 3U Slave Series
1.9.6 “Share” connector
The 2 pole WAGO socket “Share” on the rear side of the device is provided for con-
nection to equally named sockets on compatible power supplies series to achieve
a balanced load current distribution during parallel connection and constant voltage
operation. The socket is also used to connect the power supply to compatible elec-
tronic loads, in order to build a two-quadrants operation setup. Following power supply
and electronic load series are compatible on the so-called “Share bus”:
• PSI 9000 WR 3U / PSI 9000 3U SLAVE
• PSI 9000 2U - 24U
• ELR 9000
• EL 9000 B / EL 9000 B HP / EL 9000 B 2Q
• PSE 9000
• PS 9000 1U / 2U / 3U *
* From hardware revision 2, see type label of those series (in case it does not show “Revision” on type label, it is revision 1)
1.9.7 “Sense” connector (remote sensing)
The devices of series PSI 9000 WR 3U Slave are supposed to run as slave units in a
master-slave system where the remote sensing feature is only used and connected
to the master unit. For stand-alone operation outside of a master-slave setup this
feature can be wired and used on the Slave mode as well.
In order to compensate for voltage drops along the DC cables to the load, the Sense
input can be connected to the load. The maximum possible compensation is given
inthetechnicalspecications.
In order to ensure safety and to comply to international directives, insulation of high
voltage models, i. e. such with a nominal voltage of 500 V or higher, is ensured by
using only the two outer pins of the 4-pole terminal. The inner two pins, marked with
NC, must remain unconnected.
1.9.8 Master-Slave bus
A further port is provided on the rear side of the device, comprising two RJ45 sockets,
which enables multiple identical devices to be connected via a digital bus to create a
master-slave system. For a PSI 9000 WR 3U Slave device this interface is essential,
becauseitisconguredandcontrolledregardingvaluesandstatusviathisportby
a master unit.
Connection is made using standard CAT5 cables. These can theoretically have a
length of up to 1200 m, but it is recommended to keep the connections as short as
possible.

PSI 9000 WR 3U Slave Series
2. Installation & commissioning
2.1 Transport and storage
2.1.1 Transport
• The handles on the front side of the device are not for carrying!
• Because of its weight, transport by hand should be avoided where possible. If unavoidable then
only the housing should be held and not on the exterior parts (handles, DC output terminal,
rotary knobs).
• Do not transport when switched on or connected!
• When relocating the equipment use of the original packing is recommended
• The device should always be carried and mounted horizontally
• Use suitable safety clothing, especially safety shoes, when carrying the equipment, as due to
its weight a fall can have serious consequences.
2.1.2 Packaging
It is recommended to keep the complete transport packaging for the lifetime of the device for relocation or return
to the manufacturer for repair. Otherwise the packaging should be disposed of in an environmentally friendly way.
2.1.3 Storage
In case of long term storage of the equipment it is recommended to use the original packaging or similar. Storage
must be in dry rooms, if possible in sealed packaging, to avoid corrosion, especially internal, through humidity.
2.2 Unpacking and visual check
After every transport, with or without packaging, or before commissioning, the equipment should be visually
inspected for damage and completeness using the delivery note and/or parts list (see section „1.9.3. Scope of
delivery“). An obviously damaged device (e.g. loose parts inside, damage outside) must under no circumstances
be put in operation.
2.3 Installation
2.3.1 Safety procedures before installation and use
• The device may, according to model, have a considerable weight. Therefore the proposed
location of the equipment (table, cabinet, shelf, 19” rack) must be able to support the weight
without restriction.
• When using a 19” rack, rails suitable for the width of the housing and the weight of the device
are to be used (see „1.8.3. Specic technical data“
• Before connecting to the mains ensure that the supply voltage is as shown on the product
label. Overvoltage on the AC supply can cause equipment damage.
2.3.2 Preparation
2.3.2.1 Planning the master-slave system
Before any further planning of installation and wiring it’s recommend to decide how the master-slave system shall
becongured.Thesmallestsetupwouldconsistof1xPSI9000WR3Uand1xPSI9000WR3USlave.Both,
master and slave unit, must be of same rating regarding voltage, current and power. Because the PSI 9000 WR
3U Slave models are only available with 15 kW power, they will only match the corresponding models of PSI 9000
WR3Useries.“Match”ishererelatedtotheuseofthemaster-slavebus,whichwouldn’tacceptdi󰀨erentmodels.
It means, that paralleling a PSI 9080-170 WR 3U with a PSI 9080-510 WR 3U is technically possible and accept-
able (due to the same voltage rating), but not supported regarding master-slave.
