1.0CONNECTIONS
POWER CONNECTIONS:
POWERTEC Brushless DC motor controllers are supplied with nominal input voltages of 230, 380, and 460VAC. Three phase input power is required. The input is not phase sensitive. Connect the appro- priate power supply to the input fuses at L1, L2, and L3 (check nameplate for proper input voltage and capacity).
Connect the output terminals T1, T2, and T3 to the respective terminals on the Brushless DC motor. It is very important that the T1 terminal on the motor connects to T1 on the drive, T2 of the motor connects to T2 of the drive, and T3 of the motor connects to T3 of the drive. An earth ground wire of the same gauge as the motor power leads or one gauge smaller (no smaller than #14 AWG) must be run from a bolt

in the motor junction box to the ground terminal on the drive. A wire must then be run from the ground terminal on the drive (next to the motor terminals) to an earth ground at or near the power source. The Model 1000 drive does not have the common circuitry connected to earth ground (chassis). In most cases this works best, but in some cases it does not. POWERTEC recommends connecting a short jumper wire from the drive common at any one of the several places available on the terminal strips to a nearby point on the drive chassis or backpanel that will establish this ground. This is more important in applications where multiple drives are connected together or serial communications from a host are used. All other POWERTEC drives have the common grounded by mounting screws on the regulator boards.
