6.3.5 Voltage circuit connection
If a 220 V or higher circuit is used, use a transformer.
The transformer which has primary voltage of VT less than 6600V and secondary voltage of VT not more than
220V can be used. For connection to P1 to P3 terminals on RE81WH, connect the secondary of transformer.
Make sure that terminal symbols are correct.
In order to perform maintenance work such as changing the wire layout and replacing equipment, we
recommend that you connect protective device (breaker) for the voltage input circuit (P1, P2, and P3 terminals).
