SK 500E – Brief instructions for frequency inverters

Note USS Bus modules and Modbus RTU
No optional modules are required for communication via USS or Modbus RTU.
The USS protocol is integrated into all SK 5xxE series devices. An interface is available via terminal X11, or if
present, also via X7:73/74.
Modbus RTU is only available with version SK 54xE or higher. For this, the same interfaces as for USS apply.
A detailed description of both of these protocols can be found in Manual BU 0050.

Installing
Note Installing the technology unit
Modules should not be inserted or removed unless the device is free of voltage. The slots may only be used for
the intended modules.
Installation of a technology unit separate from the frequency inverter is not possible. It must be connected directly
to the frequency inverter.
The technology units must be installed as follows:
1. Switch off the mains voltage, observe the
waiting period.
2. Push the control terminals cover down
slightly or remove.
3. Remove the blank cover, by loosening the
release on the lower edge and pulling off
with an upward turning movement. If
necessary, the attachment screw next to the
release must be removed.
4. Hook the technology unit onto the upper edge slots and press in lightly until it engages.
Ensure full contact with the connector strip and fasten with the screws if necessary (separate
packet).
5. Close the control terminal cover again.
