4. Relays, contactors, solenoids or coils of electromechanical brake installed close to the inverters
may occasionally generate interference in the control circuitry. To eliminate this effect, RC
suppressors (with AC power supply) or freewheel diodes (with DC power supply) must be
connected in parallel to the coils of these devices.
5. When using the external HMI (refer to
), the cable that connects to
the inverter must be separated from the other cables in the installation, keeping a minimum
distance of 10 cm (3.95 in).
3.2.6 Cable Separation Distance
Provide separation between the control and the power cables according to
