Dangerous voltages can be present at the motor connection terminals even when the inverter is
switched off. Always use insulated screwdrivers on these terminal fields.
Ensure that the input voltage source is not live before setting up or changing connections to the
unit.
Make sure that the inverter and motor are specified for the correct supply voltage.
In order to access the electrical connections, the SK 200E must be removed from the SK T14 connection
