1397 AC Input Line Connections

Figure 23 - 1397 - 1.5…30 Hp at 230 VAC, 3…60 Hp at 460 VAC, 7…110 A at 380/415 VAC

ATTENTION: If the AC input power system does not have a neutral or one phase

referenced ground, an isolation transformer with the neutral of the secondary

grounded is highly recommended. If the line-to-line voltages on any phase can

exceed 125% of the nominal line-to-line voltage, an isolation transformer with

the neutral of the secondary grounded, is always required. Failure to observe

these precautions could result in bodily injury or damage to equipment.
