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!
•
All work on DC connections must be carried out under zero voltage, i.e. DC output not
connected to a load and may only be performed by qualified and informed persons.
Improper actions can cause fatal injury as well as serious material damage.
•
Never touch AC cables or AC connectors and terminal directly after unplugging from
mains supply as the danger of electric shock remains!
•
Never touch the contacts on the DC output terminal directly after switching off the DC
output, because there still can dangerous voltage present, sinking more or less slowly
depending 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.
•
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 modules may only be installed or removed after the device is switched off. 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 configure the various protecting features against overcurrent, overpower etc. for sensi
-
tive loads to what the target application requires!
