9.1.2 MCB Control Test
In order to test correct operation of the MCB control, the breaker must
still remain in TEST position. Charge the DC to full level and record the
MCB control and feedback signals, see example in Figure 9-1 below.
Note that signal numbering in the picture may be different in the current
SW version.
Discharge the DC voltage using Emergency OFF button from the
cabinet door or from external emergency OFF. Check that the MCB
control works properly, that feedback signals comes correctly to the SW
and DC is discharged with VLU/RBU.
Charge and close the MCB again and open this time by making a trip to
the drive. (for example changing parameter 32.4 Earth Fault Alarm to
FC1). Record the MCB signals and DC voltage. Check that signal are
correct and that the DC is discharged (short delay, based on rotor time
constant is used before discharging is started).

9.1.3 MCB Emergency Stop/Off
Check emergency stop and off functionality before starting up the drive
and later also while the motor is in running condition!
