Auxiliary Logic/Alternate Power Wiring Supply - Emerson Control Techniques EN Series Installation Manual

Do not connect or disconnect AC power by inserting or removing the AC power
connector. Using the connector in this manner, even once, will damage the connector
making it unusable.

Auxiliary Logic/Alternate Power Wiring Supply

Auxiliary Power Supply (APS) allows the drive to retain motor position information and
serial communications when the main AC power supply is disconnected. You must reset the
drive, either using the reset button or a reset input, after AC power is re-applied if the backup
supplies have been active.
