3.2.9 Retrofit kit, SK TU2 cover
(SK TU2 cover for SK 300E Size1/Size2, Part No.: 275113050)
The retrofit kit for the NORDAC trio SK 300E is screwed on top of the
SK 300E in the position of the technology unit. This module contains a
blind plate with the same measurements as other technology units, a
suitable seal and 6 screws for fastening.
This retrofit kit is used so that any technology units which are no longer
required, e.g. the PotentiometerBox, can be removed from the SK
300E and the retrofit kit screwed on in its place. This ensures that the
maximum protection class IP55/IP66 is maintained.
In addition, two LEDs are visible from outside the blind plate on the left
side. These indicate the actual device status.
LED Description
Green LED [ON] The green LED indicates that the mains voltage is present and operational,
while a flashing code that increases in speed shows the degree of overload
at the frequency inverter output.
Red LED [ERROR] Indicates actual error by flashing with a frequency according to the number
code of the error.
NOTE
If a technology unit has not been ordered together with the SK 300E, it is always
delivered with a blank cover. This means that an extra retrofit kit does not need to
ordered for this SK 300E.
