Danger to life due to electric shock when touching exposed DC
conductors or DC plug contacts if the DC connectors are damaged or
loose
The DC connectors can break or become damaged, become free of the DC cables, or no
longer be connected correctly if the DC connectors are released and disconnected
incorrectly. This can result in the DC conductors or DC plug contacts being exposed.
Touching live DC conductors or DC plug connectors will result in death or serious injury due
to electric shock.
• Wear insulated gloves and use insulated tools when working on the DC connectors.
• Ensure that the DC connectors are in perfect condition and that none of the DC
conductors or DC plug contacts are exposed.
• Carefully release and remove the DC connectors as described in the following.
11. Unlock the DC connector using the corresponding
unlocking tool and remove (refer to the
manufacturer manual for further information).
12. Ensure that no voltage is present at the DC inputs on
the inverter using a suitable measuring device.
13. Unscrew (TX25) all 10 screws of the enclosure lid of
the AC-Connection Unit and remove the enclosure
lid carefully towards the front.
14. Set the screws and the enclosure lid aside and store safely.
15. Ensure there is no voltage on the AC terminal block between L1 and N, L2 and N, and L3 and
N using a suitable measuring device. To do so, insert the test probe (maximum diameter:
2.5 mm (0.078 in)) into the measuring points of the respective terminal blocks.
16. Ensure that there is no voltage on the AC terminal block between L1 and grounding
conductor, L2 and grounding conductor, and L3 and grounding conductor using a suitable
measuring device. To do so, insert the test probe (maximum diameter: 2.5 mm (0.078 in)) into
the measuring points of the respective terminal blocks.
