5. Relays, contactors, solenoids or coils of electromechanical brakes installed close to the inverter may eventually
create interferences in the control circuitry. To eliminate this effect, RC suppressors (with AC power supply)
or free-wheel diodes (with DC power supply) shall be connected in parallel to the coils of these devices.
6. On inverters of frame size D IP2X/Nema1, a shield kit is supplied for better organization of the cables of the
communication network. For further information, refer to the installation data sheet supplied with the kit.
