Emerson E Series User Manual

Installation
AC Power Supply Requirements
The examples below show AC power connections for single phase and three
phase E Series Drives. These examples are shown for reference only. Local
electrical codes should be consulted before installation.
Note: The maximum voltage applied to the drive terminals must not exceed
264 VAC phase to phase and phase to PE ground. This can be
accomplished by referencing the AC supply to earth ground.
If the distribution transformer is configured as shown in Figure 11 or Figure
12, the AC power supply can be connected directly to the amplifier terminals.
