WARNING!
• DO NOT connect ncomng AC power to output termnals U, V, W, or termnals
B+, B-! Severe damage to the drve wll result .
• Leakage current may exceed 3 .5 mA AC . Mnmum sze of the protectve earth
(PE) conductor shall comply wth local safety regulatons for hgh leakage current
equpment .
NOTE
• WIRE AND GROUND IN ACCORDANCE WITH NEC OR CEC, AND ALL
APPLICABLE LOCAL CODES .
• Motor wres MUST be run n a separate steel condut away from control wrng
and ncomng AC power wrng .
• Do not nstall contactors between the drve and the motor wthout consultng AC
Technology for more nformaton . Falure to do so may result n drve damage .
• Use only UL and CSA lsted and approved wre .
• Mnmum wre voltage ratng s 300 V for 120, 208, and 240 Vac systems, and
600 V for 400 and 480 Vac systems .
• Wre gauge must be based on a mnmum of 125% of the rated nput/output current
of the drve, and a mnmum 75°C nsulaton ratng . Use copper wre only .
