The Y adapters must not be used to interrupt the DC circuit.
• Do not use the Y adapters in the immediate vicinity of the inverter. The adapters must not
be visible or freely accessible.
• In order to interrupt the DC circuit, always disconnect the inverter as described in this
document (see Section 10, page 54).

1. Ensure that the circuit breaker is switched off and that it cannot be accidentally reconnected.
2. If the enclosure lid is mounted, remove it as follows:
• Turn the DC load-break switch towards OFF until it snaps into place at position O.
• Unscrew all the screws of the enclosure lid using an Allen key (AF 5) and remove the
enclosure lid. Ensure that the conical spring washers are not lost.
3. Ensure that no ground fault is present.
4. Flip the DC contact protection up and press
firmly until it snaps into place.
