3.1.1 Assembly of an SK CU5-STO and SK CU5-MLT customer unit

DANGER
Danger of electric shock
The frequency inverter has a hazardous voltage for up to 5 minutes after it has been switched off.
• Only carry out work when the frequency inverter has been disconnected and at least 5 minutes
have elapsed since the mains was switched off!
Installation must be carried out as follows:
1. Switch off the mains voltage, observe the waiting period.
2. Push the control terminal cover down and remove it.
3. Remove the blank cover by activating the release mechanism at the lower edge and removing it
with an upward rotating movement.
4. Break out the internal jumper of the STO contact with the aid of a small screwdriver or small
needle-nose pliers. Otherwise the customer unit cannot be installed.
Information
Once the jumper has been removed, the frequency inverter cannot be operated with functional safety
without CU5.
5. Hook the customer unit onto the upper edge and press in lightly until it engages. Take care that the
connector strip makes proper contact.
6. Install the control terminals and blank cover.
