[. . . ] G7 Adjustable Speed Drive Quick Start Guide Document Number: 51671-003 Date: March, 2005 Introduction Congratulations on the purchase of your new G7 True Torque Control2 Adjustable Speed Drive (ASD). The G7 True Torque Control2 Adjustable Speed Drive is a solid-state AC drive that features True Torque Control2. TIC's Vector Control Algorithm enables the motor to develop high starting torque and provide compensation for motor slip, which results in smooth, quick starts and highly efficient operation. The G7 uses digitally-controlled pulse width modulation. [. . . ] Note: Ensure that the ventilation openings are not obstructed. ASDs produce high-frequency noise -- steps must be taken during installation to avoid the negative effects of noise. Listed below are some examples of measures that will help to combat noise problems. · · · · · · Separate the input and output power conductors of the main circuit. Do not install the input and output wires in the same duct or in parallel with each other, and do not bind them together. Do not install the input or output power conductors of the main circuit and the wires of the control circuit in the same duct or in parallel with each other, and do not bind them together. Use shielded wires or twisted wires for the control circuits. Ensure that the grounding terminals (G/E) of the ASD are securely connected to ground. Connect a surge suppressor to every electromagnetic contactor and every relay installed near the ASD. Install noise filters as required. Connecting the ASD DANGER Refer to the section titled Installation Precautions on pg. 4 and the section titled Lead Length Specifications on pg. 16 before attempting to connect the ASD and the motor to electrical power. System Grounding Proper grounding helps to prevent electrical shock and to reduce electrical noise. The ASD is designed to be grounded in accordance with Article 250 of the 2005 NEC or Section 10/Part One of the Canadian Electrical Code (CEC). The grounding conductor shall be sized in accordance with Article 250-122 of the NEC or Part OneTable 6 of the CEC. Note: The metal of conduit is not an acceptable ground. The input, output, and control lines of the system shall be run in separate metal conduits and each shall have its own ground conductor. Power Connections DANGER L1/R, L2/S, and L3/T are the 3-phase input supply terminals for the ASD. The ASD may be operated from a single-phase supply. When operating using a single-phase supply, use the L1 and L3 terminals. 14 G7 ASD Quick Start Guide T1/U, T2/V, and T3/W are the output terminals of the ASD that connect to the motor. An inductor may be connected across terminals PA and PO to provide additional filtering. When not used, a jumper is connected across these terminals (see Figure 15 on pg. Connect the input and output power lines of the ASD as shown in Figure 4. Note: In the event that the motor rotates in the wrong direction when powered up, reverse any two of the three ASD output power leads connected to the motor. Figure 4. ASD/Motor connection diagram. Connect the 3-phase input power to the input terminals of the ASD at L1/R, L2/S, and L3/T. Connect the output of the ASD to the motor from terminals T1/U, T2/V, and T3/W. [. . . ] Application-specific applicables, wire insulation type, conductor material, and local and regional regulations are but a few of the considerations when selecting the actual lug and wire type to be used with the ASD. Cable/Terminal specifications are based on the rated current of the ASD and Do Not include the 10% Service Factor. Note: For further installation information see the section titled Installation and Connections on pg. 230-volt G7 ASD Cable/Terminal Specifications.
