5.1 Power circuit
Operating and measuring voltage area on 3 phase system:
Main voltage: 100 Vac - 480 Vac (±20 %)
Phase voltage: 57.7 Vac - 277 Vac (±20 %)
AUX voltage: 24 Vdc - 110 Vdc (-10 to +15 %)
Frequency: 50 Hz - 60 Hz (±10 %)
Operating and measuring voltage area on 1 phase system:
Phase voltage: 57,7 Vac - 240 Vac (±20 %)
AUX voltage: 24 Vdc - 110 Vdc (-10 to +15 %)
Frequency: 50 Hz - 60 Hz (±10 %)
Phase setting, see the Section 7.
If 1 phase system is used and the voltage level is between 57,7 Vac - 109 Vac the auxiliary power supply
(AUX) must be used.
