Basic safety notes

05/STM-48V/en/2011-04-01/CW

Risk of burns due to contact with hot surfaces!

During operation, the surface temperature of the STM may ex-
ceed +85°C (+185°F).



Allow the module to cool down to at least +40°C (+104°F)
before working on the module.



Measure the surface temperature before touching the module.



Wear protective gloves, if necessary.

Risk of electric shock due to contact with live parts!



Before conducting work on the machine and the auxiliary
equipment, disconnect them from the power supply and make
sure they cannot be accidentally switched back on again.



Wait until the frequency converter is discharged.
