The supply voltage details can be found on the 4300 & 4380 nameplate.
Please ensure that the unit is suitable for the electrical supply on which it is to
be used. The mains supply for Design Envelope pumps is as follows:
1 × 200-230v ± 10%,
3 × 200-230v ± 10%,
3 × 380-480v ± 10%,
3 × 575-600v ± 10%
Frequency - 50/60Hz
