Alternative 2 – Using the holes inside the cabinet1. Attach the cabinet to the floor through the bottomattaching holes with M10 to M12 (3/8” to 1/2”) bolts.The recommended maximum distance betweenthe front edge attaching points is 800 mm (31.5”).2. If the back attaching holes are not accessible, at-tach the cabinet at the top to wall with L-brackets(not included in the delivery) using the lifting lugattaching holes.M16Miscellaneous￭ Cable duct in the floor below the cabinetA cable duct can be constructed below the 500 mm wide middle part of the cabinet. Thecabinet weight lies on the two 50 mm wide transverse sections which the floor must carry.Prevent the cooling air flow from the cable duct to the cabinet by bottom plates. To ensurethe degree of protection for the cabinet, use the original bottom plates delivered with theunit. With user-defined cable entries, take care of the degree of protection, fire protectionand EMC compliance.500 (19.68”) 50 (1.97”)500 (19.68”)50 (1.97”)￭ Arc weldingABB does not recommend attaching the cabinet by arc welding. However, if arc welding isthe only option, connect the return conductor of the welding equipment to the cabinet frameat the bottom within 0.5 meters (1’6”) of the welding point.Note:The thickness of the zinc plating of the cabinet frame is 100 to 200 micrometers (4 to 8 mil).WARNING!Make sure that the return wire is connected correctly. Welding current must notreturn via any component or cabling of the drive. If the welding return wire isMechanical installation 53
