Connecting ExtVtg
Qualified person
Always connect the cable to the ExtVtg connection as follows.
Additionally required material (not included in the scope of delivery):
- Suitable bootlace ferrules if using stranded wire
Cable requirements:
- Copper wire
- Conductor cross-section: 0.2 mm² to 2.5 mm²
- The cable length must be less than 3 m.
Procedure:
- On the Sunny Island, attach the M20 cable gland to the PE/ExtVtg enclosure opening with the counter nut (torque: 5 Nm).
- Strip 7 mm of the cable insulation.
- Lead the cable through the cable gland into the Sunny Island.
- Connect the insulated conductors to the 2-pole terminal blocks included in the scope of delivery (torque: 0.5 Nm to 0.6 Nm, blade width: 1 mm):
Connect the line conductor to terminal ExtVtg L.
Connect the neutral conductor to terminal ExtVtg N.
- Ensure that the conductors are plugged completely into the terminals up to the insulation.
- In accordance with the labelling, plug the 2-pole terminal block into the connection ExtVtg on the inverter until the terminal block audibly snaps into place.
- Ensure that the seal insert is positioned correctly in the cable gland.
- Tighten the swivel nut of the cable gland (torque: 2.6 Nm).
