The transformer has multiple tappings on the primary side for the standard range of voltages on which the drive operates. The factory
default wiring connects to the highest voltage tapping on the primary side, and the trip settings for the -FC4 terminal is set
accordingly. The customer can change the tapping provided the correct voltage is applied and the thermal magnetic circuit breaker is
set accordingly.
