Requirements:
☐ The technical requirements of the multifunction relay must be met (see Section 10 "Technical
Data", page 65).
☐ All electrical installations must be carried out in accordance with the local standards and the
National Electrical Code
Requirements on・the conductors:
• Conductor cross-section: 0.2 mm² to 1.5 mm² (24 AWG to 16 AWG)
• The conductor type and wiring method must be appropriate for the application and location.
Procedure:
1.
Danger to life due to high voltages
• Ensure that the inverter is disconnected from all voltage sources (see Section 8,
page 61).
2. Remove the sealing plug from the enclosure opening on the multifunction relay.
3. Insert the conduit fitting into the opening and tighten from the inside using the counter nut.
4. Attach the conduit to the conduit fitting.
5. Guide the conductors from the conduit into the inverter.
6. Strip off the conductor insulation by max. 9 mm (0.35 in).
7. Connect the conductors to the 3-pole terminal block
according to the circuit diagram, depending on the
operating mode (see Section 6.4.3, page 37).
Ensure that the conductors are plugged completely
into the terminal points (round openings) up to their
insulation.
8. Stick the terminal block into the MFR slot on the
communication assembly in the inverter.
9. Ensure that the terminal block is securely in place.
10. Ensure that all conductors are correctly connected.
11. Ensure that the conductors sit securely in the terminal points. Tip: To release the conductors
from the terminal block, open the terminal points using a suitable tool.
