UL/CSA markings
The ACS800-U7 and the ACS800-07+C129 are C-UL US listed. The ACS800-07+C134 is CSA
marked. The approvals are valid with rated voltages (up to 600 V).
The drive is suitable for use on a circuit capable of delivering not more than 100,000 rms symmetrical
amperes at the drive nominal voltage (600 V maximum for 690 V units) when protected by fuses given
in the NEMA data fuse table. The ampere rating is based on tests done according to UL 508A.
The drive provides overload protection in accordance with the National Electrical Code (US) and
Canadian Electrical Code (Canada). 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.
Equipment warranty and liability
The manufacturer warrants the equipment supplied against defects in design, materials and
workmanship for a period of twelve (12) months after installation or twenty-four (24) months from date
of manufacturing, whichever first occurs. The local ABB office or distributor may grant a warranty period
different to the above and refer to local terms of liability as defined in the supply contract.
The manufacturer is not responsible for
• any costs resulting from a failure if the installation, commissioning, repair, alternation, or ambient
conditions of the drive do not fulfil the requirements specified in the documentation delivered with
the unit and other relevant documentation.
• units subjected to misuse, negligence or accident
• units comprised of materials provided or designs stipulated by the purchaser.
In no event shall the manufacturer, its suppliers or subcontractors be liable for special, indirect,
incidental or consequential damages, losses or penalties.
If you have any questions concerning your ABB drive, please contact the local distributor or ABB office.
