Electrical installation 111multiple inverter cubicles (ie. two cubicles of two modules each), make sure that the motorcabling is identical for both cubicles. ProcedureRemoving the inverter module(s)To allow more room for cabling work, the inverter module can be removed completelyinstead of only the fan carriage.Refer to the drawings below.WARNING! Obey the instructions in chapter Safety instructions. If youignore them, injury or death, or damage to the equipment can occur.1. Do the steps in section Electrical safety precautions (page 19) before you start thework.2. Open the cubicle door.3. Remove the shroud at the top of the cubicle.4. Detach the terminal block [X50] at the top of the module.5. Detach the DC busbars from the module. Make note of the order and position of thescrews and washers.6. Detach the wiring connected to the terminals on the front of the module (including fiberoptic cabling). Move the disconnected wiring aside.7. Attach the module extraction/installation ramp (included) to the base of the cabinet sothat the tabs on the mounting bracket enter the slots on the ramp.WARNING! Do not use the module extraction/installation ramp with plinth heightsover 50 mm.8. Remove the two screws at the bottom front of the module.WARNING! Before you proceed, make sure the cabinet is level, or chock thewheels of the module.9. Remove the two screws at the top front of the module.10. Pull the module carefully out along the ramp. While pulling on the handle with yourright hand, keep a constant pressure with one foot on the base of the module toprevent the module from falling on its back.11. Move the module into a safe location outside the immediate work area and make sureit cannot topple over. Chock the wheels of the module if the floor is not completelylevel.12. Repeat the procedure for the other inverter modules (if any).13. Frame 1×R8i + 1×R8i only: Repeat the procedure for the supply module.14. Frame 1×R8i + 1×R8i only: Remove the LCL filter module as described on page 168.Proceed to Connecting the motor cables (page 117).
