Electrical Installation

Electrical Interface—possible permanent damage

• Handle connections and cables with special care!
• Do not kink cable, do not bend around small radii, do not route around sharp edges!
• Do not apply tensile stress, use strain relief!

Motor

By default, the «EC frameless DT» is supplied without connector. It has three individual strands to connect 
to the motor windings 1, 2, and 3 as well as two additional individual strands for the NTC thermistor.
