Interference emission

With regard to interference emission, the inverter meets the EMC limit values of the standard EN 61800-3:2004. The inverters are suitable for industrial as well as household applications (light industry).

To ensure the best possible electromagnetic compatibility, install the inverters as described in chapter Installation. In doing so, make sure there are good grounding connections for the inverters. Use shielded motor cables to comply with the specifications on interference emission.

The following table defines the conditions for use in drive applications.

Inverter type

Cat. C1 (class B)

Cat. C2 (class A)

Cat. C3

according to EN 61800-3

230 V, 1-phase

LTPBxxxx-2B1-x-xx

No additional filtering required.

Use a shielded motor cable.

230 V, 3-phase

LTPBxxxx-2A3-x-xx

400 V, 3-phase

LTPBxxxx-5A3-x-xx

Use an external filter of type NF LTxxx xxx.

Use a shielded motor cable.

No additional filtering required.

Use a shielded motor cable.

575 V, 3-phase

LTPBxxxx-603-x-xx

 

525 V, 3-phase

LTPBxxxx-U03-x-xx

These devices are not covered by the EMC standard.

Use an external line filter, if necessary, to minimize electromagnetic interference emissions.

However, compliance with the aforementioned limit classes cannot be guaranteed.

Use a shielded motor cable.
