Model Numbers: CAD32-50A / LC1D09-32A
Important Safety Information
DANGER: HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH. Disconnect all power before servicing equipment. Failure to follow these instructions will result in death or serious injury.
WARNING: HAZARD OF FIRE OR ELECTRIC SHOCK (FOR CONTACTOR WITH UL HI-FAULT SHORT CIRCUIT CURRENT RATINGS ONLY). The opening of the branch-circuit protective device may be an indication that a fault current has been interrupted. To reduce the risk of fire or electric shock, current-carrying parts and the other components of the controller should be examined and replaced if damaged. Failure to follow these instructions can result in death, serious injury, or equipment damage.
WARNING: This product can expose you to chemicals including Antimony oxide (Antimony trioxide), which is known to the State of California to cause cancer. For more information go to www.P65Warnings.ca.gov.
Electrical equipment should be installed, operated, serviced, and maintained only by qualified personnel. No responsibility is assumed by Schneider Electric for any consequences arising out of the use of this material.
