Example

[1]

The mechanical installation of a drive unit with hollow shaft does not create a conductive connection of drive unit and mounting plate. In this case, a low-impedance, Hf-capable equipotential bonding with HF litz wire is required. The mechanical installation of a drive unit without hollow shaft creates a conductive connection of drive unit and mounting plate. In this case, the entire contact surface must be electrically conductive (e.g. unpainted).

The contact surfaces must be electrically conductive (e.g. unpainted). For improved low-impedance grounding at high frequencies, SEW‑EURODRIVE recommends using corrosion-resistant connecting elements. Tighten the M5 screw with a tightening torque of 2.0 Nm – 2.5 Nm.
