AC output cable connection procedure
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.
WARNING! Do the steps in section Electrical safety precautions on page 12
before you start the work.
Refer to Planning the electrical installation on page 57 and Dimension drawings on page
117.
1. Remove the shroud from the output 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.
• Remove the screws of the inner cover.
• 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.
3. If it is a shielded cable, prepare the cable ends and do the grounding at the cabinet
entry. Connect the twisted shield of the AC output cables to the cabinet PE (ground)
busbar with a cable lug.
4. Connect the phase conductors to terminals L1, L2 and L3.
5. If it is present, connect the separate PE/grounding conductor to the cabinet PE
(ground) busbar.
6. Install the cable lead-through and make sure that its ingress protection level matches
the inverter ingress protection level.
