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
waiting period.
2.
slightly or remove.
3. Remove the blank cover, by loosening the
release on the lower edge and pulling off
necessary, the attachm ent 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 t he connector strip and fasten with the screws if necessary (separat e
packet).
5. Close the control terminal cover again.
