UL/CSA Markings

The ACS800-PC UL and cUL listed.

The drive is suitable for use on a circuit capable of delivering not more than 100 kA

rms symmetrical amperes at the drive nominal voltage (480V maximum).

The drive provides overload protection in accordance with the National Electrical

Code (US). See ACS800 Firmware Manual for setting. Default setting is off; the

setting must be activated at start-up.

The drives are to be used in a heated indoor controlled environment. See section

"Ambient Conditions" for specific limits.

ABB brake choppers, when applied with appropriately sized brake resistors, will

allow the drive to dissipate regenerative energy (normally associated with quickly

decelerating a motor). Proper application of the brake chopper is defined in chapter

"Resistor Braking". This can be applied to a single drive or multiple drives with DC

bus connected to allow a sharing of regenerative energy.
