Apieceofequipmentwhichisintendedfordisposalmust,accordingtoEuropeanlawsandregulations(ElektroG,
WEEE)bereturnedtothemanufacturerforscrapping,unlessthepersonoperatingthepieceofequipmentoran-
other,delegatedpersonisconductingthedisposal.Ourequipmentfallsundertheseregulationsandisaccordingly
marked with the following symbol:
The device contains a Lithium battery cell. Disposal of that battery follows the above stated rule
orspeciclocalregulations.
1.5 Product key
Not abailable
1.6 Intended usage
Theequipment isintended tobe usedonly asa variablevoltage andcurrent sourceor onlyas avariablecurrent sink.
TypicalapplicationforavoltagesourceisDCpowersupplytoanyrelevantuser,includingwhenusedasbattery
chargertotestchargevariousbatterytypes,andforcurrentsinksthereplacementofanohmicresistorbyan
adjustable electronic DC load in order to load relevant voltage and current sources of any type.
AdditionallytothefunctionalityoftheequipmentassourceorsinkofelectricalenergyontheDCside,allmodelsin
thisseriesarealsoso-calledrecuperatingdevicesandthusnotjustdrainenergyontheACside,butalsosource
energy when being sinks on the DC side. This is where the term “bidirectional” comes from. In sink mode the de-
vicesbecomeenergyrecoverers,butarenotdenedorconsideredasenergygenerationequipment.
• Claims of any sort due to damage caused by non-intended usage will not be accepted
• All damage caused by non-intended usage is solely the responsibility of the operator

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 60 V models according to SELV can’t generate hazardous DC voltage.
• Never touch cables or connectors directly after unplugging from mains supply as the
danger of electric shock remains!
• Never touch the contacts on DC terminal directly after switching the device o󰀨, because
when running in source mode there still can be dangerous voltage present, sinking more
or less slowly depending on the load!
• There can be dangerous potential between DC minus to PE or DC plus to PE due to
charged X capacitors, even when the DC output/input is not switched on and the device is
still running. Never touch PE and any of the DC poles at the same time with bare hands!
• 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
• In situations where the device works in source mode, with a voltage > 0 adjusted and
the DC output being on, the output voltage can remain at the last setting after switching
the DC output o󰀨 again, in case the set value of current for the internal load (sink mode)
is set to 0
• Even with the DC terminal being switched o󰀨, the device can generate a small, not load-
able voltage (< 2 V) on this terminal!
• The equipment must only be used as intended
• Theequipment is onlyapprovedfor use withinthe connection limitsstated on the productlabel.
• 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.
• Whenoperatingthedeviceaspowersupply:donotconnectloads,particularlysuchwithlow
resistance,tothedevicewhiletheDCoutputisswitchedon;sparkingmayoccurwhichcan
cause burns as well as damage to the equipment and to the load.
• Whenoperating thedeviceas electronicload: do notconnect powersources to thedevice while
theDCinputisswitchedon;sparkingmayoccurwhichcancauseburnsaswellasdamageto
the equipment and to the source.
• ESDregulations must beapplied whenplugginginterface cardsor modules intothe relative slot
• Interfacecardsormodulesmayonlybeattachedorremovedafterthedeviceisswitchedo󰀨.
It’s not necessary to open the device.
• Donot connectexternal powersources withreversed polarityto theDC terminal!Theequipment
willbedamaged,evenwhencompletelypoweredo󰀨.
• Never connect external power sources to the DC terminal that can generate a higher voltage
than the rated voltage of the device!
• Never insert a network cable which is connected to Ethernet or its components into the mas-
ter-slave sockets on the rear side of the device!
• Alwayscongurethevariousprotectingfeaturesagainstovercurrent,overpoweretc.forsen-
sitive loads to what the target application requires!
• When operating the device as electronic load: always make sure that the energy recovery can
feed back the inverted energy and that it does not switch to isolated operation. For situations
ofisolatedoperationasupervisiondevice(AIU,gridandplatprotection)hastobeinstalled
• It’s not allowed to run the device onAC sources such as generators or UPS equipment. It must
only be connected to a power grid!
