EMC-compliant installation
When installed in accordance with the instructions for EMC-compliant installation MOVITRAC
®
0500
inverters meet the requirements for compliance with EMC Directive 89/336/EEC.
Interference immunity:
MOVITRAC
®
0500 frequency inverters comply with all the immunity requirements of EN 50082-2. In
combination with shielded leads even more stringent levels than those stipulated in the standard are
met.
Interference emission:
Higher levels of interference are permitted for industrial environments. In an industrial environment,
one or several of the below listed measures may be done without, depending on the supply system
specifications and the specifics of the installation.
To meet emission limits for the residential commercial and light industrial environment (class B limit
to EN 55011) we recommend the following measures:
●
Connect an appropriate NF...-... input filter on the line side.
– MOVITRAC
®
0504-231-1-00
→
NF005-231 input filter
– MOVITRAC
®
0508-231-1-00
→
NF008-231 input filter
– Mount the NF.. input filter close to the corresponding MOVITRAC
®
0500, but outside
the minimum ventilation space required.
– Keep the connecting lead between the input filter and the MOVITRAC
®
0500 as short
as possible: a maximum lead length of 400 mm is permissible. Unshielded, twisted-conductor
leads are satisfactory.
●
Provide the input filter and the MOVITRAC
®
0500 with an earth which is effective at RF, i.e.
– Wide-area metallic contact between the inverter housing and ground, for instance with the
sheet metal of the switch cabinet housing.
●
Shield all leads apart from the power cable.
– Laying the cables in separate, earthed metal ducts or conduits is also effective as a shield.
– The shield must be earthed by the most direct possible route, with a wide-area contact to
ground at both ends. If necessary, then one end may be earthed via an interference
suppression capacitor to prevent earth loops. Alternatively, use double-shielded cable with
the outer shield earthed at the MOVITRAC
®
and the inner shield at the other end.
