Notes:
1. An isolation transformer is not required for “LD” controls (115VAC, 1phase).
2. For LD-4, the power requirements cannot be met by 115VAC 1phase input power. It is recommended that a
230VAC input power be used with an isolation transformer to provide 115VAC 3 phase input power for an LD-4.
3. Line power limitations with 1 phase prevents the chassis and drives from delivering full continuous rated output
power.
