5. After motor installation is complete a guard of suitable dimensions must be constructed and installed around the motor This guard must prevent personnel from coming in contact with any moving parts of the motor or drive assembly but must allow sufficient cooling air to pass over the motor If a motor mounted brake is installed provide proper safeguards for personnel in case of brake failure WARNING Guards must be installed to form a safe and uncompromised perimeter around rotating parts such as couplings pulleys external fans and unused shaft extensions All parts should be permanently guarded to prevent accidental contact by personnel Accidental contact with body parts or clothing can cause serious or fatal injury When this motor is installed according to these instructions it complies with the EEC Machinery Directive Electromagnetic Compatibility EMC requirements for CE compliance are met when the incoming power is purely sinusoidal HAZARDOUS LOCATIONS Ensure that the motor installed is proper for the location in which it will operate Division 2 motors should never be installed in locations requiring a Division motor Familiarize yourself with the ratings and the specific details of the motors working environment CLASS I Gases Vapors Group A Acetylene Group B Butadiene ethylene oxide hydrogen propylene oxide Group C Acetaldehyde cyclopropane diethel ether ethylene isoprene Group D Acetone acrylonit
