2.9.2.5
Phase Rotation
Rectifier modules are not sensitive to phase rotation.
2.9.2.6
Phase Voltage
The Input Phase Voltage is detailed in Table 2–16.
Nominal voltage is a.c. r.m.s, 3 phase, 3-wire and earth/ground.
The equipment will operate with a variation of ±10% of the nominal supply voltage. For supply voltages below
the nominal, there will be a corresponding reduction in maximum output power. The equipment can operate
up to a maximum of +15% variation on the nominal supplies for a maximum of 30 cycles duration without the
equipment tripping though reduced performance may be observed.
