NOTICE!
OPERATOR RESPONSIBILITY
According to the EN 61800–3 standard for variable-speed
drive systems, the operator is responsible for ensuring
EMC compliance. Manufacturers can offer solutions for
operation conforming to the standard. Operators are
responsible for applying these solutions, and for paying
the associated costs.
There are 2 options for ensuring electromagnetic compati-
bility.
•
Eliminate or minimize interference at the source
of emitted interference.
•
Increase the immunity to interference in devices
affected by its reception.
RFI filters
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 filters.

NOTICE!
RADIO INTERFERENCE
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 E1h–E4h drives control and relay terminals comply with
PELV (excluding grounded Delta leg above 400 V).
Galvanic (ensured) isolation is obtained by fulfilling
requirements for higher isolation and by providing the
relevant creepage/clearance distances. These requirements
are described in the EN 61800–5–1 standard.
Electrical isolation is provided as shown (see Figure 10.26).
The components described comply with both PELV and the
galvanic isolation requirements.
