15. Ensure the conductors are plugged into the terminal
points (round openings) as far as is will go and not
into the actuation shafts (rectangular openings).
16. Ensure that the terminal points are allocated to the correct conductors.
17. Ensure that the conductors are plugged completely into the terminal points up to their
insulation.
18. Install outlet in desired position (e.g. next to the inverter or as switch/outlet combination
optionally at short distance from the inverter (to max. 10 m (33 ft))).
19. Connect the other end of the cable using it directly as energy supply to the outlet.
Connect the switch for secure power supply operation
Connection overview
Requirements for 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.
☐ Maximum length of conductors: 10 m (33 ft)
Procedure:
1. Ensure that the inverter is disconnected from all voltage sources (see Section 8, page 65).
2. Remove the sealing plug from the opening for connecting the switch for secure power supply
operation.
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 into the inverter.
6. Strip off the conductor insulation by min. 6 mm (0.24 in) to max. 10 mm (0.39 in).
7. Connect the conductors to the 2-pole terminal
blocks. Ensure that the conductors are plugged
completely into the terminal points up to their
insulation.
