This chapter gives a description of the manual. This manual is applicable for low voltage AC and DC drive systems. The drive system in this manual consists of the supply transformer, input power cable of the drive, the variable speed drive (frequency converter), motor cable and motor. Each DISTRIBUTION BOX and controller must be grounded. The grounding system provides a low-impedance path for fault current and limits the voltage rise on the normally non-current-carrying metallic components of the electrical distribution system. The voltage, system arrangement, loads connected, and continuity of. Navigating the grounding and bonding of electrical systems can be a tall task unless you have taken the time to familiarize yourself with the requirements of Article 250 of NFPA 70 ®, National Electrical Code® (NEC ®). Where should you start? The following are some common questions from individuals.
