WARNING! Obey the inverter safety instructions. If you ignore them, injury or
death, or damage to the equipment can occur. If you are not a qualified
electrician, do not do installation or maintenance work.

1. Remove the shroud from the input power terminals.
• Remove the screws at the bottom of the outer shroud.
• Pull the outer shroud slightly up and away from the inverter. A suction-cup tool
helps to remove and install the outer shrouds.

• Carefully pull to remove the inner cover. Prevent damage to the sealing gasket.
• Remove the cable lead-throughs.
2. Feed the cables into the cabinet.

lug.
4. Connect the DC- conductor to terminal DC- and the DC+ conductor to terminal DC+.
5. If there is a separate PE conductor, connect it to the cabinet grounding terminal.
6. Install the cable lead-through and make sure that its ingress protection level matches
the inverter ingress protection level.
