Vari-Green® Motor
The SP/CSP-A700-VG and SP/CSP-A1050-VG models utilize a Vari-Green® motor. The Vari-Green motor is an electronically commutated (EC) motor that uses AC input power and internally converts it to a DC power supply which provides an 80% turndown capability and increased energy savings.
Textual Description of Motor Image: A green, cylindrical electric motor with red and black wires connected to a terminal block, and a smaller white wire bundle. It is mounted on a metal bracket.
Tri-Voltage: 115V or 208-230/277V
ATTENTION
The motor is prewired at the factory for 115V operation. If disconnected, red jumper wire has 120 VAC potential. Ensure leads are capped/covered with the supplied caps in the hardware package.
The tri-voltage feature allows the motor to operate at 115/208-230/277V. The operating voltage is selected via the voltage jumper wire.
When the jumper wire is connected, the motor operates at 115V. Textual Description of Figure 1: Two wires are shown connected together with a wire nut. One wire is red, and the other is black. This configuration indicates 115V operation.
When the jumper wire is disconnected and capped, the motor operates at 208-230/277V. Textual Description of Figure 2: A red wire is shown capped with a plastic connector, and a black wire is also capped. This configuration indicates 208-230/277V operation.
Balance Dial
The speed control dial (P/N 385806) is mounted on the power pack bracket and is to be plugged into the 9-pin connector on the motor. To increase speed, rotate the dial clockwise. To decrease speed, rotate the dial counterclockwise. From 0-1.9V the motor will be off and will operate in the 2-10V range. See Figure 3 for dial mounting location.
