Chapter 1 PowerFlex 7000 Drive Overview
ArcShield Technology The PowerFlex 7000 drive with ArcShield™ technology significantly reduces
arc flash hazards and minimizes the risks that are associated with the
operation and maintenance of electrical equipment. ArcShield technology is
available for AFE Direct-to-Drive configurations and is designed to help
protect employees and minimize unplanned outages and downtime. The
PowerFlex 7000 drive system with ArcShield option is a fully integrated Allen-
Bradley® CENTERLINE® controller and PowerFlex 7000 drive combination.
This safety feature redirects the energy from an arc flash event through the top
of the enclosure. Personnel protection is maintained while in front, at the side,
or behind the enclosure and when the low voltage control door is open.
The PowerFlex 7000 drive with ArcShield technology meets the following
safety standards:
• IEEE C37.20.7
• CSA C22.2 No. 22-11
• EEMAC G14-1
• IEC 62271-200 Annex AA
•IEC 62477-2 (DRAFT)
Arc resistant enclosures contain the pressure from an arc flash event using
reinforced support members, plates, and uses 12-gauge steel for all doors,
sides, roof, and back sheets.
Bolted MV doors with robust door hinges add to the security of the main doors.
An aluminum pressure relief vent on the roof opens to redirect the pressure
upwards. A plenum exhaust system, above the pressure relief vent, channels
the superheated gas, vaporized copper, and steel to a controlled location.
