• Thelabpowersupplymaybesetupandusedonlyindry,closedindoorspaces.Itmaynotbecomemoistorwet.Thepower
supply 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the
permitted ambient conditions for operation.
• Choosealocationforthelabpowersupplythatisstable,even,cleanandsufcientinsize.
• Donothaveanyopenamesinthedirectvicinityofthelabpowersupplyanddonotplaceanycontainerswithliquidson
or near the device.

duetoelectricshock.Thus,alwaysallowthelabpowersupplytoreachroomtemperaturebeforeconnectingittothepower
outlet and turning it on and/or using it.
• Beforeandduringuse,makesurethatyourhands,shoes,clothing,theoor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is
not 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.Avoid
excessive thermal stress on the mains cable from extreme heat or cold. Do not modify the mains cable. Otherwise the mains
cable 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 circuit
breaker) 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 a
similarlyqualied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lledwithliquidrightnexttothedevice.Ifliquidoranobjectenters

the 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 low
voltage guideline.
• During use, the lab power supply produces heat. Never insert any objects into the product’s air vents and do not obstruct
ventilation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. Safe
operation 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-carrying
components.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speciedtypeandratedcurrent.Theuseofmendedfusesisnotpermittedasthisposesarehazard!
• For installations in industrial facilities, follow the accident prevention regulations for electrical systems and equipment of the
government 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 be
supervised 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
