Here are some tips to help you with an industrial AC drive start up.

Before You Start

• VFDs are mounted in an appropriate environment and required input circuit protection.
• Install all electrical conduit, if needed, prior to the AC drive start up
• The electrical in/out 3Ø power cable have been pulled and are terminated onto VFDs.
• The AC motors are mounted and are uncoupled from the load, if possible, to facilitate an auto tune of the VFD with access to the motor name plate data.
• The communication signals are pulled and are near the field connection terminals on the VFD.

AC Drive Start Up Steps

• Verify the drive model number to ensure it's the correct model
• Ensure the area surrounding the drive complies with specifications
• Verify that the drive is properly sized to run the motor
• Confirm there is proper circuit protection as specified by national and local code
• Properly wire drive terminals R/L1, S/L2, T/L3 & R/T1. V/T2, W/T3 and control wiring
• Properly ground the drive and tighten control and grounding terminal according to specification
• Program the VFD according to the motor nameplate data and customer’s expectations
