1395 Power Connections - Standard Field Voltage

Figure 19 - 1395 - 1…30 Hp, 230VAC / 2…60 Hp, 460VAC Series

ATTENTION: The motor field supply is phase sensitive. To guard against

possible drive/motor damage, assure that the connections are properly made

according to Figure 19

, Figure 20 on page 55, Figure 21 on page 55, and

Figure 22 on page 56

IMPORTANT

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.
