Mounting the protective covers
1. Tighten all protective covers (torque: 5 Nm).
2. Ensure that the protective covers are firmly in place.
12.3.1.2 Disassembling and Mounting the Panels
Danger to life due to electric shock or electric arc if live components are touched
• Switch off the inverter and wait at least 15 minutes before opening it to allow the capacitors to discharge
completely.
• Disconnect the inverter (see Section 7, page 96).
Property damage due to rupture of grounding conductors
The components are connected to the inverter via the grounding conductor. If the roof is not disassembled correctly,
the grounding conductors may be pulled out.
• Take care not to damage the grounding conductors during disassembly.
Disassembling the panels
1. Remove the screws of the front panels using a Torx screwdriver (head size T30).
2. Detach the grounding straps from the panels.
3. Remove the panels.
Mounting the panels
Requirement:
☐ The protective covers in the connection area must be mounted (see Section 12.3.1.1, page 163).
Procedure:
1. Attach the grounding straps to the panels of the interface cabinet (torque: 8 Nm to 10 Nm).
2. Ensure that the grounding straps are firmly in place.
3. Attach the panels using a Torx screwdriver (torque: 2 Nm to 3 Nm, head size T30).
