6 Electrical Connection
Connect the switch for secure power supply operation
Requirements on･the conductors:
☐ Conductor cross-section: 0.2 mm² to 2.5 mm² (24 AWG to 14 AWG)
☐ The conductor type and wiring method must be appropriate for the application and location.
Procedure:
1. Remove the sealing plug from the opening for connecting the switch for secure power supply
operation.
2. Insert the conduit fitting into the opening and tighten from the inside using the counter nut.
3. Attach the conduit to the conduit fitting.
4. Guide the conductors into the inverter.
5. Strip off the conductor insulation by min. 6 mm (0.24 in) to max. 10 mm (0.39 in).
6. Connect the conductors to the 2-pole terminal
blocks. Ensure that the conductors are plugged
completely into the terminal points up to their
insulation.
7. Stick the terminal block into the slot
battery interface module in the inverter.
8. Ensure that the terminal block is securely in place.
9. Ensure that all conductors are correctly connected.
10. 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.
11. Install the switch in the desired position (e.g. next to the inverter or as switch/outlet
combination optionally at short distance from the inverter).
12. Connect the other end of the two-core cable directly to the switch.
