3.4.1 AC Input Voltage Taps
The factory configured input voltage is shown in the serial tag label at the back of the power
source cabinet. If it is required to change the factory set input voltage configuration, a new EMI
filter and circuit breaker may have to be installed depending on what filter and breaker was
originally installed. Refer to the table below for input wiring configuration settings and EMI filter
and CB part numbers.
