7 Commissioning
Only the requirements for functional safety will be dealt with here. A detailed section regarding the
commissioning of the standard functions of the SK 200E frequency inverter can be found in the manual BU
0200 GB.
ATTENTION
DANGER TO LIFE!
The frequency inverter is not equipped with a line main switch and is therefore always live when
connected to the power supply. Live voltages may therefore be connected to a connected motor
at standstill.
For the implementation of a safety function (STO or SS1), in addition to a safe shut-down method, a digital
input is used, which should be assigned a special function. Because of this, when commissioning, a PC with
an RS232/458 interface, or alternatively a SimpleBox/ParameterBox is required for parameterisation.
Configuration by means of the DIP switches alone is not possible!
Care must be taken that the DIP switches "I/O" (S1:4 and S1:5) are in the position "0" ("off"). It is only in this
position that the digital inputs can be assigned the function "Disable Voltage" [10] or "Fast Stop" [11] via the
parameters P420 [-
01]…[-04] (see Section "Parameterisation").
