1.6 Intended usage
The equipment is intended to be used, if a power supply or battery charger, only as a variable voltage and current
source, or, if an electronic load, only as a variable current sink.
Typical application for a power supply is DC supply to any relevant user, for a battery charger the charging of vari-
ous battery types and for electronic loads the replacement of an ohmic resistor by an adjustable DC current sink
in order to load relevant voltage and current sources of any type.
• 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 40 V models according to SELV can not 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 out-
put, because there still can dangerous voltage present, which has to still to sink to safe
levels by the internal discharge circuit! There also can be dangerous potential between
negative DC output to PE or positive DC output to PE due to charged X capacitors,
which may not discharge at all!
• 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 back side of the device!
• Always congure the various protecting features against overvoltage overpower etc. for sensi-
tive loads to what the currently used application requires

1.7.2 Responsibility of the user
The equipment is in industrial operation. Therefore the operators are governed by the legal safety regulations.
Alongside the warning and safety notices in this manual the relevant safety, accident prevention and environmental
regulations must also be applied. In particular the users of the equipment:
• must be informed of the relevant job safety requirements
• must work to the dened responsibilities for operation, maintenance and cleaning of the equipment
• before starting work must have read and understood the operating manual
• must use the designated and recommended safety equipment.
Furthermore, anyone working with the equipment is responsible for ensuring that the device is at all times techni-
cally t for use.
1.7.3 Responsibility of the operator
Operator is any natural or legal person who uses the equipment or delegates the usage to a third party, and is
responsible during its usage for the safety of the user, other personnel or third parties.
The equipment is in industrial operation. Therefore the operators are governed by the legal safety regulations.
Alongside the warning and safety notices in this manual the relevant safety, accident prevention and environmental
regulations must also be applied. In particular the operator has to
• be acquainted with the relevant job safety requirements
• identify other possible dangers arising from the specic usage conditions at the work station via a risk assessment
• introduce the necessary steps in the operating procedures for the local conditions
• regularly control that the operating procedures are current
• update the operating procedures where necessary to reect changes in regulation, standards or operating con-
ditions.
• dene clearly and unambiguously the responsibilities for operation, maintenance and cleaning of the equipment.
• ensure that all employees who use the equipment have read and understood the manual. Furthermore the users
are to be regularly schooled in working with the equipment and the possible dangers.
• provide all personnel who work with the equipment with the designated and recommended safety equipment
Furthermore, the operator is responsible for ensuring that the device is at all times technically t for use.
1.7.4 User requirements
Any activity with equipment of this type may only be performed by persons who are able to work correctly and
reliably and satisfy the requirements of the job.
• Persons whose reaction capability is negatively inuenced by e.g. drugs, alcohol or medication may not operate
the equipment.
• Age or job related regulations valid at the operating site must always be applied.
Danger for unqualied users
Improper operation can cause person or object damage. Only persons who have the necessary
training, knowledge and experience may use the equipment.
Delegated persons are those who have been properly and demonstrably instructed in their tasks and the atten-
dant dangers.
Qualied persons are those who are able through training, knowledge and experience as well as knowledge of
the specic details to carry out all the required tasks, identify dangers and avoid personal and other risks.

1.7.5 Alarm signals
The equipment o󰀨ers various possibilities for signalling alarm conditions, however, not for danger situations. They
are signalled optically (on the display as text) and electronically (pin/status output of an analog interface) and
digitally (digital interface). All alarms will cause the device to switch o󰀨 the DC output.
The meaning of the signals is as follows:
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
(OverPower)
• Shutdown of the DC output due to excess of the preset limit
• Non-critical, protects the load from excessive power consumption
Signal PF
(Power Fail)
• DC output shutdown due to AC undervoltage or defect in the AC input
• Critical on overvoltage! AC input circuit could be damaged
1.8 Technical Data
1.8.1 Approved operating conditions
• Use only inside dry buildings

(1 Related to the nominal values, the accuracy denes the maximum deviation between an adjusted values and the true (actual) value.
(2 The display error adds to the error of the related actual value on the DC output
