SINGLE/THREE PH
This parameter allows the installer to
configure the E3 for single-phase or three-
phase mode. When set to single-phase
mode, the E3 will report L3 monitoring
parameters as 0 and only use L1 and L2 to
calculate Average, Imbalance, and total
monitoring parameters.

FLA SETTING
The motor’s full load current rating is
programmed in this parameter. Refer to
Chapter 3 for instructions related to service
factor, maximum continuous rated (MCR)
motors, and wye-delta (star-delta)
applications.
This parameter is used to program the low-
speed FLA value of a two-speed motor.
