Trapped key interlock (option)
The drive can be part of a trapped key interlocking system (1 in Fig. 3-11). The interlocking
system ensures that access to drive system equipment is only possible in a predefined and
safe sequence.
The key interlocks are not supplied. If the option is ordered, the drive is prepared for
the installation.

Protection IGCTs
The drive features a fuseless protection design. The IGCTs are placed between the rectifier and
the DC link. If a severe fault occurs, the IGCTs directly isolate the inverter from the main
power supply.
For information on the installation and type of key interlocks supported, see
"Mechanical interlock" [10].
