This step-by-step guide shows the manual deactivation of the Citroën C5 X HV system. A second person must be present when you carry out the steps outlined here. Tools and equipment may need to be procured to carry out the work. The "instructed person" (IP) qualification level 1S is not allowed to perform independent activation even after completing the full training process. Deactivation can only be done under the supervision and guidance of a qualified person who possesses at least the qualification specified in DGUV Information 209-093 "Qualifications for work on production vehicles with high-voltage systems" Chapter 5.1.4 (5. Qualification for work on production vehicles; Qualification level 2S: Qualified person). If it is not possible to establish or verify the absence of voltage, the vehicle must be handed over to a person who holds the qualification level 3S (Qualified person for work on live HV systems) according to DGUV-I 209-093.
