Risk of burns when touching the DC protective cover
The DC protective cover can get hot during operation.
• Do not touch the DC protective cover.
9. Use an appropriate measuring device to ensure that
no voltage is present at the AC terminal block
between L1 and N, L2 and N, and L3 and N.
Insert the test probe into each round opening of the
terminal.
10. Use an appropriate measuring device to ensure that no voltage is present at the AC terminal
block between L1 and PE, L2 and PE, and L3 and PE. Insert the test probe into each round
opening of the terminal.
11. If you are using the multifunction relay, ensure that no voltage is present between any of the
terminals on the multifunction relay and PE on the AC terminal block.
12. Use a current clamp to ensure that no current is present in the DC cables.
13. Note the position of the DC connector in order to be able to connect it again later in the same
position.
14.
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.
