10.15.4 EMC Compatibility
N O T I C E
OPERATOR RESPONSIBILITY
According to the EN 61800-3 standard for variable-speed drive systems, the operator is responsible for ensuring EMC compliance.
Manufacturers can oer solutions for operation conforming to the standard. Operators are responsible for applying these solu-
tions and for paying the associated costs.
There are 2 options for ensuring electromagnetic compatibility:
Eliminate or minimize interference at the source of emitted interference.
Increase the immunity to interference in devices aected by its reception.
RFI lters
The goal is to obtain systems that operate stably without radio frequency interference between components. To achieve a high level
of immunity, use drives with high-quality RFI lters.
N O T I C E
In a residential environment, this product can cause radio interference, in which case supplementary mitigation measures may be
required.
PELV and galvanic isolation compliance
All control and relay terminals comply with PELV (excluding grounded Delta leg above 400 V). To obtain galvanic (ensured) isolation,
fulll requirements for higher isolation and provide the relevant creepage/clearance distances. These requirements are described in
EN 61800-5.1.
Electrical isolation is provided as shown in Illustration 80. The components described comply with both PELV and the galvanic isola-
tion requirements.
