1 General information
With the SK OPR1-AUM control box it is possible to set a connected NORD frequency inverters from the
series SK 200E or SK 750E series frequency inverter into the operating modes "Normal operation" and
"Maintenance mode". Switchover between the modes is carried out by means of a detachable key switch.
The switch setting "No function" also prevents the control of the digital inputs of the frequency inverter.
The control box is designed for permanent connection to the frequency inverter. For this, appropriate
interfaces (SK CU1-STD or SK CU1-MLT for SK 750E or SK CU2-STD for SK 300E) are available as
options. The SK 200E is connected directly to the integrated terminal bar. Further information about the
interfaces can be found in the relevant manual for the frequency inverter.
