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 qualied 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.
• Never touch a blank contact on the DC input right after usage of the device, because
between DC- and DC+ there is potential against ground (PE) which needs some time
to discharge!
• 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 off.
It is not necessary to open the device.
• Do not connect external power sources with reversed polarity to DC inputs 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.

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.
