Connecting the AC Cable
Qualified person
Requirements:
The grid voltage must be within the permissible range. The exact operating range of the inverter is specified in the operating parameters .
Procedure:
- Disconnect the miniature circuit breaker from all 3 line conductors and secure against reconnection.
- Ensure that the DC load-break switch is in the O position.
- If your country requires the DC load-break switch to be protected against reconnection, secure the DC load-break switch against reconnection with a padlock.
- Unscrew the screws of the enclosure lid with a Torx screwdriver (TX 25) and remove the enclosure lid carefully forward.
- Remove the adhesive tape from the enclosure opening for the AC connection.
- Insert the cable gland M32x1.5 into the opening and tighten it with the counter nut from the inside.
- Route the AC cable into the inverter through the cable gland. If necessary, slightly loosen the swivel nut of the cable gland.
- Dismantle the AC cable.
- Strip off the conductor insulation by 18 mm to 20 mm each.
- If necessary, provide each conductor with a bootlace ferrule.
- Press the locking lever of terminal PE upward, guide conductor PE into the terminal, and press locking lever downward again.
- For connection without a neutral conductor, use the jumper provided to bridge terminal blocks PE and N. For this, press the locking levers of terminals PE and N upward, guide the jumper into the terminals, and press the locking levers downward again.
- Press the locking levers of terminals L1, L2, L3, and if applicable N upward, guide conductors L1, L2, L3, and if applicable N into the terminals according to the labeling, and press the locking levers downward again.
- Ensure that the correct conductors are assigned to all the terminals.
- Ensure that all conductors are securely in place.
