☐ The AC and DC electric circuits are isolated from the enclosure. If required by the National
®
Electrical Code ANSI/NFPA 70 or Canadian Electrical Code
responsible for grounding the system.
☐ The connection requirements of the grid operator must be met.
☐ The grid voltage must be within the permissible range. The exact operating range of the
inverter is specified in the operating parameters.
Procedure:
1. Disconnect the miniature circuit breaker from all 3 line conductors and secure against
reconnection.
2. Ensure that the AC load-break switch and the DC load-break switch are in the O position and
are secured against reconnection.
3. If the enclosure lid of the AC-Connection Unit is
mounted, remove all ten screws of the enclosure lid
(TX 25) and remove the enclosure lid towards the
front.
4. Remove the adhesive tape from the enclosure opening for the AC connection.
5. Insert the conduit fitting into the opening and tighten from the inside using the counter nut.
6. Attach the conduit to the conduit fitting.
7. Guide the conductors from the conduit into the AC-Connection Unit.
8. Connect the equipment grounding conductor either to the connection plate or to the DIN rail
terminal.
9. For the connection to the connection plate: strip the insulation of the equipment grounding
conductor by 27 mm (1.06 in).
10. Slightly loosen one of the screws with which the clip is connected to the connection plate and
completely remove the other screw (TX25).
11. Place the equipment grounding conductor on to the
connection plate, guide the clip over the equipment
grounding conductor and tighten both screws
(TX25, torque: 6 Nm (53 in-lb)). In doing so, make
sure that the conductor is lying on the connection
plate.
12. For the connection to the DIN rail terminal: strip the insulation of the equipment grounding
conductor by 18 mm (0.7 in).
