* Factory Programmed as follows: For 208-230v / 60 Hz = 208, 460v /

60 Hz = 460, 200-230v / 50 Hz = 200, 380 / 50 Hz = 400.

† Motor Nameplate Amps. Factory programmed per Programmed Set-

tings in Table 6. This value should always be compared to the actual
motor nameplate value before start-up.

** Maximum Output Amps — Factory programmed per Table 6.
