An inverter, as it is, has an Ingress Protection quite low (IP20).

That’s the reason why we need to respect the following criteria of its work environment.

– Ambient temperature:-10°C to 40°C

– Avoid electromagnetic interferences and move it away from interferences sources.

– Avoid droplet, water vapour, dust, dirt and small metal dust penetration.

– Avoid oil, salt and corrosive gas penetration.

– Avoid vibrations.

– Avoid exposure to humidity or rain. Humidity must be below 90% (without condensation).

– Never use it in a dangerous environment (explosive gas, flammable, combustible, liquid of solid).

In order to meet the requirements as much as possible, the variable frequency drive must be integrated in metal or plastic cabinets.

Be careful to the external dimensions of the product by taking into account a sufficient margin for cooling air flow circulation.

A variable frequency drive, as any electronic element, must be protected electrically upstream by a circuit breaker of the right size.
