Operation on two phases

The power supply can also be used on two phases of a three-phase system. Such a phase-to-phase connection is permissible as long as the supply voltage is below 240 V+10 %.

Make sure that the conductor connected to the N terminal is fused appropriately.

The maximum permissible voltage between one phase and the PE must be below 300 Vac.
