17 3. Installation 3.1. Mounting configurations The NT5C05CA / CB / CC rectifiers are designed for installation in a 1200 A cabinet ( NT6C43CB ) or in a standard frame ( NT6C40 or equivalent ). In this chapter, a different procedure is provided for each mounting method. The rectifiers are shipped loose, not mounted in the frame or cabinet. Upon reception, remove the rectifier from its shipping carton and inspect it for physical damage. Report any damage to your immediate supervisor. 3.

18 Installation CAUTION Preventing damage caused by over-tightening Do not over-tighten nuts and bolts. Over-tightening can strip the threads or break the bolts. Apply the appropriate torque values. CAUTION Personal safety and protecting the equipment Use a dolly truck, forklift, or hoist whenever possible when handling and moving the equipment, as power equipment is heavy. If a forklift is used, do not remove the packing material before having moved the equipment to its fi
