Main Circuit Wiring

This section gives information about the functions, specifications, and procedures necessary to safely and
correctly wire the main circuit in the drive.
NOTICE: Damage to Equipment. Do not energize and de-energize the drive more frequently than one time each 30 minutes. If
you frequently energize and de-energize the drive, it can cause drive failure.
Note:
Soldered wire connections can become loose over time and cause unsatisfactory drive performance.
