Connect signal source to MFR
Qualified person
Additionally required material:
Conduit (trade size: 27 mm (1 in) or smaller with suitable reducer bush)
Sealing compound for sealing the join between the conduit and inverter if a weep hole has been added to the conduit
Rain-tight conduit fittings or conduit fittings for wet locations complying with UL 514B (trade size: 27 mm (1 in) or smaller with suitable reducing bush)
Requirements:
The technical requirements of the multifunction relay must be met ( > Technical Data).
Procedure:
- Disconnect the inverter from all voltage sources ( > Disconnecting the Inverter from Voltage Sources).
- Insert the conduit fitting into the opening and tighten from the inside using the counter nut.
- Remove the filler plug from the enclosure opening which is located at the bottom of the inverter.
- Attach the conduit to the conduit fitting.
- Guide the conductors from the conduit into the inverter.
- Strip the insulation off the conductor 6 mm (0.24 in).
- Connect the conductors to the 3-pole terminal block according to the operating mode. Ensure that the conductors are plugged completely into the terminal points up to their insulation.
- Insert the three-pole terminal block with the connected conductors into the MFR slot.
- Ensure that the terminal block is securely in place.
- Ensure that all conductors are correctly connected.
- Ensure that the conductors sit securely in the terminal points. Tip: To release the conductors, open the terminal points using a suitable tool.
- If a weep hole has been added to the conduit, seal the conduit with sealing compound.
