Safety instructionsRead the operating instructions carefully and especially observe the safety information. If you do notfollow the safety instructions and information on proper handling in this manual, we assume no liabilityfor any resulting personal injury or damage to property. Such cases will invalidate the warranty/guarantee.Persons / Product• The lab power supply conforms with protection class I and is suited for connection only to a grounded power outlet(230 V/AC, 50 Hz). Make sure that the ground connection is not defective/interrupted as there is a risk of fatal injury in caseof malfunction.• This product is not a toy, keep it out of the reach of children.Children cannot recognize the dangers that may arise when handling electrical devices. Children may alter settings or insertobjects into the air vents on the lab power supply. This poses a risk of fatal injury due to electric shock! Always use the productout of the reach of children.• Do not leave packaging material lying around carelessly. These may become dangerous playing material for children.• The lab power supply may be set up and used only in dry, closed indoor spaces. It may not become moist or wet. The powersupply may not be exposed to extreme temperatures, direct sunlight, vibrations or mechanical stress.• Use the lab power supply only in mild climates, never in the tropics. Review the section on “Technical data” to see thepermitted ambient conditions for operation.• Choose a location for the lab power supply that is stable, even, clean and sufficient in size.• Do not have any open flames in the direct vicinity of the lab power supply and do not place any containers with liquids onor near the device.• When you carry the lab power supply from a cold to a warm room, condensation may form. This poses the risk of fatal injurydue to electric shock. Thus, always allow the lab power supply to reach room temperature before connecting it to the poweroutlet and turning it on and/or using it.• Before and during use, make sure that your hands, shoes, clothing, the floor and the device itself are dry.• Make sure that the insulation of the lab power supply, of the safety plugs, of all connected cables and of the power cable isnot damaged or destroyed. Avoid using unprotected wires.• The mains outlet must be located near to the device and be easily accessible.• Never pull the mains plug from the socket by pulling at the cable. Always pull it from the mains socket using the intended grips.• Unplug the mains plug from the mains socket if you do not use the device for an extended period of time.• Disconnect the mains plug from the mains socket in thunderstorms for reasons of safety.• Make sure that the mains cable is not squeezed, bent, damaged by sharp edges or put under mechanical stress. Avoidexcessive thermal stress on the mains cable from extreme heat or cold. Do not modify the mains cable. Otherwise the mainscable may be damaged. A damaged mains cable can cause a deadly electric shock.• Do not touch the mains cable if it is damaged. First, power down the respective mains socket (e.g. via the respective circuitbreaker) and then carefully pull the mains plug from the mains socket. Never use the product if the mains cable is damaged.• A damaged mains cable may only be replaced by the manufacturer, a workshop commissioned by the manufacturer or asimilarly qualified person, so as to prevent any danger.• Never plug in or unplug the mains plug when your hands are wet.• Never pour any liquids over electrical devices or put objects filled with liquid right next to the device. If liquid or an object entersthe interior of the device nevertheless, first power down the respective socket (e.g. switch off circuit breaker) and then pullthe mains plug from the mains socket. Do not operate the product anymore afterwards, but take it to a specialist workshop.• When using the device, do not carry any conductive metal objects or jewelry such as chains, bracelets, rings, etc.• Never leave the lab power supply unattended during use.• Shield all connected units from malfunction and from excess voltage.• Connecting several devices in in series may cause dangerous voltage which can pose a risk of fatal injury. Heed the lowvoltage guideline.• During use, the lab power supply produces heat. Never insert any objects into the product’s air vents and do not obstructventilation in any way. The power supply is cooled primarily via convection. Thus, never cover the lab power supply.• In case safe operation is no longer guaranteed, cease use of the device immediately and shield it from unintended use. Safeoperation is no longer guaranteed when:- the power supply is visibly damaged,- the power supply no longer functions,- the power supply was stored for an extended period under adverse conditions or- if the product was damaged during transport.• Do not use the lab power supply as a charger.• The lab power supply is not approved for use on persons or animals.• Opening any covers on the product or removing parts – unless this is possible by hand – may expose voltage-carryingcomponents. This poses the risk of fatal injury due to electric shock!• Disconnect the device from the power outlet before opening it.• Capacitors located in the lab power supply may still be charged even when the device is unplugged.• Only use fuses of the specified type and rated current. The use of mended fuses is not permitted as this poses a fire hazard!• For installations in industrial facilities, follow the accident prevention regulations for electrical systems and equipment of thegovernment safety organization or the corresponding authority for your country.• In schools and educational institutions, hobby and do-it-yourself workshops, the use of the lab power supply must besupervised by trained staff.• Please handle the product carefully. Jolts, impacts or a fall even from a low height can damage the product.• Also observe the safety and operating instructions of any other devices which are connected to the product.Miscellaneous• Consult an expert when in doubt about operation, safety or connection of the device.• Maintenance, modifications and repairs are to be performed exclusively by an expert or at a qualified shop.• If you have questions which remain unanswered by these operating instructions, contact our technical support service orother technical personnel.5.
