electric shock. When electric devices are operated, certain components in these devices
are always under dangerous tension.
Warning
Dangerous voltage
High voltage!
Danger of death or serious bodily injury due to electric shock!
For operation the relevant DIN, VDE, EN und IEC regulations, as well as all national and
local safety and accident prevention regulations must always be observed. The system
manufacturer or the user is responsible for ensuring that these regulations are observed.
Warning
Before switching the device on, fit the covers and protective
screens so that the device cannot be touched.
For built-in devices, make sure that there is an external housing,
such as a control cabinet, to ensure that the electric components
cannot be touched.
The standards EN 60204-1 and EN 50178 must be observed.
Warning
Ensure that the minimum copper cross section is used for the entire
length of the protective earth conductor in accordance with stan-
dard EN 60204.
Warning
Before commissioning, also for brief measuring and test pur-
poses, always connect the protective conductor to all electric
devices or connect to an earth cable in accordance with the
connection diagram.
Otherwise, high voltages may occur on the housing. These could
cause an electric shock.
Warning
Do not touch the electrical connection points of the components
when the device is switched on.
Warning
Before touching electric components with voltages over 50 V,
disconnect the device from the mains or voltage source.
Protect the device against being switched on again.
