1.7 Safety
1.7.1 Safety notices
Mortal danger - Hazardous voltage
• Electrical equipment operation means that some parts will be under dangerous voltage.
Therefore all parts under voltage must be covered!
• All work on connections must be carried out under zero voltage (input not connected to
voltage sources) and may only be performed by qualied and informed persons. Improper
actions 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.
• This electronic load device uses an inverter and in case of a failure the intermediate
circuit voltage can be present on the DC input, even if there is no voltage source con-
nected - it is recommended to never touch the metal parts of the DC input terminals
with bare hands! There also can be dangerous potential between negative DC input to
PE or positive DC input to PE due to charged X capacitors which either discharge very
slowly or not 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 congure the various protecting features against overcurrent, overpower etc. for sensi-
tive sources to what the currently used application requires

1.7.5 Alarm signals
The device oers various possibilities for signalling alarm conditions, however, not for danger situations. The sig-
nals may be optical (on the display as text) acoustic (piezo buzzer) or electronic (pin/status output of an analog
interface). All alarms will cause the device to switch o the DC input.
The meaning of the signals is as follows:
Signal OT
(OverTemperature)
• Overheating of the device
• DC input will be switched o
• Non-critical
Signal OVP
(OverVoltage)
• Overvoltage shutdown of the DC input occurs due to high voltage entering the device
• Critical! The device and/or the load could be damaged
Signal OCP
(OverCurrent)
• Shutdown of the DC input due to excess of the preset limit
• Non-critical, protects the source from excessive current drain
Signal OPP
(OverPower)
• Shutdown of the DC input due to excess of the preset limit
• Non-critical, protects the source from excessive power drain
Signal PF
(Power Fail)
• DC input shutdown due to AC undervoltage or defect in the AC input
• Critical on overvoltage! AC mains input circuit could be damaged
1.8 Technical data

1.8.3 Specic technical data (230 V models)
(1 Related to the nominal values, the accuracy denes the maximum deviation between an adjusted values and the true (actual) value.
Example: a 80 V model has min. 0.3% voltage accuracy, that is 240 mV. When adjusting the voltage to 5 V, the actual value is allowed to dier max. 240 mV, which
means it might be between 4.76 V and 5.24 V.
(2 Typical value at 100% input voltage and 100% power
(3 Set values as in the display or as data readable via digital interfaces are more accurate than the corresponding value on the DC input. Their accuracy subtracts
from the general accuracy. For actual values it is vice versa. There the display accuracy adds to the general accuracy, so the error (i.e. deviation) will be higher.
4) Already includes the accuracy of the displayed actual resistance

(1 Related to the nominal values, the accuracy denes the maximum deviation between an adjusted values and the true (actual) value.
Example: a 80 V model has min. 0.3% voltage accuracy, that is 240 mV. When adjusting the voltage to 5 V, the actual value is allowed to dier max. 240 mV, which
means it might be between 4.76 V and 5.24 V.
(2 Typical value at 100% input voltage and 100% power
(3 Set values as in the display or as data readable via digital interfaces are more accurate than the corresponding value on the DC input. Their accuracy subtracts
from the general accuracy. For actual values it is vice versa. There the display accuracy adds to the general accuracy, so the error (i.e. deviation) will be higher.

(1 Related to the nominal values, the accuracy denes the maximum deviation between an adjusted values and the true (actual) value.
Example: a 80 V model has min. 0.3% voltage accuracy, that is 240 mV. When adjusting the voltage to 5 V, the actual value is allowed to dier max. 240 mV, which
means it might be between 4.76 V and 5.24 V.
(2 Typical value at 100% input voltage and 100% power
(3 Set values as in the display or as data readable via digital interfaces are more accurate than the corresponding value on the DC input. Their accuracy subtracts
from the general accuracy. For actual values it is vice versa. There the display accuracy adds to the general accuracy, so the error (i.e. deviation) will be higher.
