2.7.4 Brake Chopper
A brake chopper can be supplied for applications that
have a regenerative load. The brake chopper connects to a
brake resistor, which consumes the braking energy,
preventing an overvoltage fault on the DC bus. The
braking chopper is automatically activated when the DC
bus voltage exceeds a specified level, depending on the
nominal voltage of the adjustable frequency drive.
2.7.5 line Power Shield
The line power shield is a Lexan cover installed inside the
enclosure to provide protection according to VBG-4
accident-prevention requirements.
