Electrical installation 119Re-installing the fan carriage of an inverter module(If the inverter module was removed completely instead of only the fan carriage, proceedto section Re-inserting the inverter module into the cubicle below.)The re-installation of the fan carriage is the removal procedure in reverse. See sectionRemoving and reinstalling the fan carriage of an inverter module (page 115).Re-inserting the inverter module into the cubicleFrame 1×R8i + 1×R8i only: This procedure applies to both the supply and invertermodules. However, do not insert the modules before connecting also the input powercables. See page 122.WARNING! Obey the instructions in chapter Safety instructions. If youignore them, injury or death, or damage to the equipment can occur.1. Make sure there are no tools, debris or any other foreign objects in the cubicle.2. If not already in place, attach the module extraction/installation ramp (included) to thebase of the cabinet so that the tabs on the mounting bracket enter the slots on theramp.3. Push the module up the ramp and back into the cubicle.• Keep your fingers away from the edge of the module front plate to avoidpinching.• Keep a constant pressure with one foot on the base of the module to preventthe module from falling on its back.4. Secure the top front of the module with two screws. Tighten to 22 N·m (16 lbf·ft).5. Secure the bottom front of the module with two screws. Tighten to 22 N·m (16 lbf·ft).6. Remove the ramp.7. Attach the DC busbars to the module. Tighten to 70 N·m (52 lbf·ft).8. Reconnect terminal block [X50] at the top of the module.9. Reconnect the wiring and fiber optic cables to the terminals on the front of the module.10. Repeat the procedure for the other inverter modules (or, in the case of frame1×R8i + 1×R8i, the supply module).11. Reinstall the shroud near the top of the cubicle.
