◆ Protection of Main Circuit Terminals
When you wire the main circuit terminals, do not let cable ends go near terminals or the drive. If you use crimped
terminals, make sure that you also use insulation caps.
◆ 6-Phase/12-Pulse Rectification
■ Installing Transformer
Install a 6-Phase/12-Pulse isolation transformer with output windings phase-shifted by 30 electrical degrees or install
a Hybrid 6-Phase topology on the power supply.
