ATTENTION: Only trained and qualified personnel familiar with the drive and associated machinery can plan or implement the installation, startup,
adjustment, and subsequent maintenance or repair of the system. You must have previous experience with and a basic understanding of electrical
terminology, configuration procedures, required equipment, and safety precautions. See the Armor PowerFlex User Manual, publication 35-UM001.
BURN HAZARD: : Surfaces may reach dangerous temperatures. Verify that the device is cool before beginning maintenance and use appropriate
personal protective equipment (PPE).

IMPORTANT
The Armor™ PowerFlex® drive can internally detect a thermal event on its dedicated dynamic brake resistor kits and shut down the Electronic
Motor Disconnect. This eliminates the need for the upstream control devices like the one shown.

AC drives do not typically offer protection for externally mounted dynamic brake resistors. A risk of fire exists if external braking resistors are not
protected from drive component failure, for example, failure of the brake IGBT. In this case, external resistor packages must be protected from an
overtemperature condition using a protective circuit, or equivalent.
