Figure 13 – Replacement EcoVFC as Master in IST-VFC Compatibility Mode
Note
: IST-VFC operates with 200-250V, 50-60 Hz, single phase power supply. EcoVFC requires 360-440V, 50-60 Hz,
three phase incoming power supply. If three phase power supply is not available, EcoVFC must be replaced with
MagVFC. MagVFC operates with 200-250V, 50-60 Hz, single or three phase power supply.
