Danger to life due to electric shock
• Disconnect the inverter from all voltage sources (see Section 8, page 53).
2. If the enclosure lid of the DC-Connection Unit is
closed, remove it as follows: Unscrew all ten screws
(TX25) and remove the enclosure lid towards the
front.
3. Set the screws and the enclosure lid aside and store safely.
4. When using conduits, perform the following steps:
• Remove the M32 cable glands from the enclosure opening. To do so, unscrew the
counter nut from the inside and remove the cable gland from the enclosure opening.
• Insert the conduit fitting into the opening and tighten from the inside using the counter nut.
• Attach the conduit to the conduit fitting.
• Lead one end of the network cable from the conduit into the inverter.
5. When using the cable glands, perform the following steps:
• Remove the swivel nut from the cable gland for the communication cable.
• Thread the swivel nut over the network cable.
• Remove the two-hole cable support sleeve from the cable gland.
• Remove the sealing plug from one of the enclosure openings of the two-hole cable
support sleeve and insert the network cable into the enclosure opening.
• Press the two-hole cable support sleeve with the cable into the cable gland and guide the
network 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.
6. When using a self-assembly network cable, assemble the RJ45 connector and connect to the
network cable (see connector documentation).
7. Put the RJ45 plug of the cable into one of the
network sockets of the communication assembly.
8. Ensure that the RJ45 plug is securely in place by pulling slightly on the cable.
