6. For STP 15000TLHE-10 / STP 20000TLHE-10:
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.
7. Pre-screw the upper enclosure lid of your inverter to
the replacement device with the 6 enclosure lid
screws and corresponding conical spring washers
and then tighten them in the sequence shown on the
right (torque: 6.0 Nm). For this purpose, use an
Allen key (AF 4).
The toothing of the conical spring washers must
point towards the enclosure lid.
The scope of delivery of the inverter includes a
spare screw and conical spring washer.
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 will forfeit their operating licence.
• Contact the SMA Service Line if one or more EMC seals is missing.
DANGER!
Danger to life due to live enclosure lid
The earthing of the upper enclosure lid is ensured by the toothed conical spring washers.
• For all 6 screws attach the conical spring washers with the toothing facing towards
the enclosure lid.
