In the case of error and for all planned dismantling, disconnect the
supply cable to the capacitor charger (plug X3 on board D927).
For Hybrid/Digital, disconnect the four plugs of battery pack
BK1-BK4 and the 300 V supply cable plug to the capacitor bank.
There is a risk of a lethal electric shock when removing the safety
cover in front of D927.
The voltages at fuse F5 of D927 can be up to 440 V!
