3.2.9 Upgrading kit, SK TU2 cover
(SK TU2 cover for SK 300E BG1/BG2, part no.: 275113050)
The NORDAC
trio
SK 300E upgrading kit is bolted on to the assembly sur-
face of SK 300E technology units from above. This kit includes a blind
cover whose dimensions are identical with those of the technology unit, an
appropriate seal and 6 screws for fixing.
Whenever a technology unit which is no longer required, for instance the
PotentiometerBox, is removed from the SK 300E, this upgrading kit can be
screwed on instead to conveniently protect the inverter so that the maxi-
mum type of protection IP55 / IP66 is still maintained.
On the left side of the blind cover two LEDs are externally visible signalling
the state the device is in.
LED
Description
green LED [ ON ]
If steady, signals that mains voltage is being applied. If flashing at a growing,
code-based rate while operation is in progress, it shows an increasing overload at
the frequency inverter output.
red LED [ ERROR ]
Signals an error applied by flashing at the rate which corresponds to the number
code of the error.
IMPORTANT
If no technology unit has been ordered for the SK 300E at all right from the start, a
blind cover is always included in the inverter scope of delivery. In other words no
upgrading kit needs to be ordered for the device in question as an extra.
