1 General
This document specifies the EM133 CANopen messaging protocol used to transfer data
between a master CANopen station and the EM133. Refer to the EM133 Installation and
Operation Manual for information on configuring communication parameters and electrical
connections.
IMPORTANT
In 3-wire connection schemes, the unbalanced current and phase readings for power
factor, active power, and reactive power will be zeros, because they have no meaning.
Only the total three-phase power values will be shown.
