Procedure:
1. If the conductor is installed in a separate conduit, mount the conduit to the enclosure opening:
• Remove the sealing plugs from the network connection opening on the inverter.
• Insert the conduit fitting into the opening and tighten from the inside using the counter nut.
• Attach the conduit to the conduit fitting.
2. Guide the conductors from the conduit into the inverter. In the process, install the conductors in
the inverter such that they do not come into contact with AC conductor.
3. Strip off the conductor insulation by 7 mm (0.28 in).
4. In the case of fine stranded wire, provide the conductors with a bootlace ferrule.
The terminal block with resistor must be inserted for proper operation.
5.
If the terminal block with resistor is not inserted, the system will not function properly.
• Plug the 4-pole terminal block with
inserted resistor into the jack RSI/SPS on
the module.
6. Connect the conductors to the terminal points of the
terminal block in accordance with the labeling and
tighten the screw terminals with the screwdriver.
7. Ensure that the conductors sit securely in the terminal point of the terminal block.
