DANGER
Dangertolifefromstoredcharges!
Electric charges may be stored in electrical components even after the system has
been switched off and disconnected from the power supply. Contact with these
componentsmayresultinseriousorfatalinjury.
1. Before working on the specified components, ensure that they have been
completelydisconnectedfromthepowersupply.
2. Allow 10 minutes to elapse in order to ensure that the internal capacitors have
beenfullydischarged.
