Make sure that all 4 EMC seals are present in the
upper enclosure lid and that they are correctly
positioned. The metal braiding of the EMC seals
must point outwards.
EMC seals
EMC seals are only installed in inverters of type STP 15000TLHE-10 / STP 20000TLHE-10.
Without EMC seals, the STP 15000TLHE-10 / STP 20000TLHE-10 no longer fulfil the
requirements of the EMC Directive (Directive on the electromagnetic compatibility of a
device) and forfeit their operating licence.
• Contact the SMA Service Line if one or more EMC seals is missing.
