• In commercial institutions, the accident prevention regulations of
the Employer's Liability Insurance Association for Electrical Sys-
tems and Operating Materials are to be observed.
• In schools and training centres as well as at hobby and DIY work-
shops, the use of power packs must be supervised by adequate-
ly trained personnel in a responsible manner.
• For safety and licensing (CE) reasons, unauthorised conversion
and/or modifications to the product are not permitted.
• Do not expose the device to high temperatures, dampness or
strong vibration or excessive mechanical loads.
• Never touch the device or the plug with wet or moist hands. There
is risk of a fatal electric shock!
• Live components may be exposed if covers are opened or parts
are removed unless this can be done by hand.
• Before opening, disconnect the device from all voltage sources.
• Never switch the device on immediately after having taken it from

adequately ventilated. Do not cover the ventilation apertures of
the device!
• Use fuses of the type and rated current specified only. Use of
repaired fuses is not permitted.
• Make sure that the earth wire is not interrupted as, in case of an
error, there could be danger to life. Further, ensure that the insu-
lation is neither damaged nor destroyed.
