After completion of the installation work, make sure to check all control and power
connections again before switching on the mains voltage. If all electrical connections
are correct, make sure that the frequency inverter is not enabled. After power-up,
the frequency inverter carries out a self-test and the relay output (X10) reports
"Fault".

Control inputs S1IND (STOA) and S7IND (STOB) open
After a few seconds, the self-test is complete, the relay (X10) picks up and signals
"no fault ".
If the unit is in "as-delivered" condition or after resetting the unit to the factory set-
tings, the guided commissioning procedure is started automatically. On the control
unit, the “SetUP“ menu from the menu branch CTRL is displayed.
