Danger to life from electric shock due to live voltage
High voltages are present in the live components of the DC subdistribution. Touching live
components results in death or serious injury due to electric shock.
• Disconnect the inverter from all voltage sources on the DC side (see the inverter manual).
• Disconnect the DC subdistribution from voltage sources (see Section 8.2, page 47)
• Disconnect all DC sub-distributions that are connected in parallel in the DC connection area
(see the manual of the respective DC sub-distribution).
