4. Remove the connection plug of the temperature control.

☑ The inverter switches off with an audible click. After approximately 2 minutes, the inverter audibly switches

the supply voltage off.

✖ There is no audible switching sound?

• Contact SMA Solar Technology AG.

5. Check whether the heating elements are radiating heat after a delay time of 5 minutes.

If the heating elements are not radiating heat, contact us (see Section 9 "Contact", page 68).

6. Insert the connection plug of the temperature control.

☑ The inverter switches the supply voltage on with an audible click. After approximately 2 minutes, the inverter

again emits an audible switching sound.

✖ There is no audible switching sound?

• Contact SMA Solar Technology AG.

7. Mount the protective covers (see Section 7.1.2, page 63).
