Procedure:
1.
Danger to life due to high voltages
• Disconnect the inverter from all voltage sources (see Section 10, page 69).
2. If the enclosure lid of the DC Connection Unit is
closed, remove it as follows: Unscrew all ten screws
with a Torx screwdriver (TX 25) and remove the
enclosure lid carefully forward.
3. Set the screws and the enclosure lid aside and store safely.
4. Remove the swivel nut from the cable gland for the communication cable.
5. Remove the two-hole cable support sleeve from the cable gland and insert the cable into the
enclosure opening of the two-hole cable support sleeve.
6. Press the two-hole cable support sleeve with the cable into the cable gland and guide the
cable to the communication assembly in the DC Connection Unit. Ensure that any unused
enclosure openings of the two-hole cable support sleeve are sealed with sealing plugs.
7. Strip 9 mm of the cable insulation at maximum.
8. Connect the cable to the 3-pole terminal block
according to the circuit diagram, depending on the
operating mode (see Section 6.5.3, page 36).
Ensure that the conductors are plugged completely
into the terminal points up to their insulation.
9. Stick the 3-pole terminal block with the connected
conductors into the MFR slot on the communication
assembly in the inverter.
10. Ensure that the terminal block is securely in place.
11. Ensure that all conductors are correctly connected.
12. Ensure that the conductors sit securely in the terminal points. Tip: To release the conductors,
open the terminal points using a suitable tool.
13. Tighten the swivel nut on the cable gland hand-tight.
