WARNING: When installing 6-lead motors extra care must be used to ensure lead identification at the surface. Leads must be marked and connected per diagram. Motor leads are not connected red to red, yellow to yellow, etc.
Each motor lead is numbered with two markers, one near each end. To reverse rotation, interchange any two line connections.
There are a number of different types of phase converters available. Each generates three-phase power from a single-phase power line.
In all phase converters, the voltage balance is critical to current balance. Although some phase converters may be well balanced at one point on the system-operating curve, submersible pumping systems often operate at differing points on the curve as water levels and operating pressures fluctuate. Other converters may be well balanced at varying loads, but their output may vary widely with fluctuations in the input voltage.
The following guidelines have been established for submersible installations to be warrantable when used with a phase converter.
