Page 16: Installing The Control Unit Onto A Din Rail
Do not install the control unit adjacent to electromagnetic disturbance sources (for example, relays, contactors, brake choppers, and power cabling). The minimum recommended distance to such components is 200 mm (7.9 in). ABB recommends that you install metallic screening between the control unit and the source of disturbance. - Page 17 Mechanical installation 17 to the figure below. The minimum cross-sectional area of the grounding conductor is 4 mm (12 AWG). Push the control unit to the rail as shown below. It makes a click. Attach the control unit to the rail with screws or end brackets. This prevents accidental movement of the control unit.
