4-6 HARDWARE DESCRIPTION Voltage Feedback Circuit Boards Voltage feedback boards are located in the converter cabinet on the far left side mounted on a vertical glass polyester channel. The boards consist of series connected resistors for sensing input voltage, DC link voltage, and output voltage. Cooling Fans There are several different arrangements of cooling fans. Fans are required to remove heat from the drive to ensure proper operation of its components. The fans draw air into the drive through the vented lower doors and exhaust it through vented enclosures at the top of the drive. 1557-UM050F-EN-P – June 2013
