Connecting Relay 1 and Relay 2

Qualified person

If you are using a multifunction relay, always connect it as follows:

Switching Behavior of the Slaves

In case of a fault, the multifunction relays of the slaves switch less reliably than the multifunction relays of the masters. In case of a fault, the slaves wait for the master to confirm the fault.

Additionally required material (not included in the scope of delivery):

  • Suitable bootlace ferrules if using stranded wire

Requirements:

Cable requirements:

  • Copper wire
  • Conductor cross-section: 0.2 mm² to 2.5 mm²

Procedure:

  1. Break through a suitable location in the cable feed-through plate with a sharp object.
  2. Strip 7 mm of the cable insulation.
  3. Lead the cable through the hole in the cable feed-through plate into the Sunny Island.

  4. WARNING

    Danger to life from electric shock due to incorrect insulation

    In the case of faulty insulation, supposedly de-energized parts or cables may be live. Touching live components or cables can result in death or serious injury due to electric shock.

    1. When connecting cables to Relay 1 and Relay 2, always insert a silicone tube.
    2. Always connect the cables to Relay 1 and Relay 2 as described in the following.

  5. Cut a silicon tube to the length of the cable in the Sunny Island.
  6. Pull the silicone tube over the cable. In this way, the cable is double-insulated.
  7. Lead the cable into the Sunny Island making sure that it does not touch any data cables.
  8. Connect the insulated conductors to the 3-pole terminal blocks included in the scope of delivery (torque: 0.5 Nm to 0.6 Nm, blade width: 1 mm). Observe the correct assignment of the connections when doing so.

    Closed when idle

    C

    Change-over contact

    NO

    Open when idle

  9. Ensure that the conductors are plugged completely into the terminals up to the insulation.
  10. In accordance with the labeling, plug the 3-pole terminal block into the connection Relay1 or Relay2 on the inverter until the terminal block audibly snaps into place.
