Here, the lugs on the rear side of the Power Unit
must be hooked into the upper recesses and the
lugs in the Connection Unit into the lower
recesses in the wall mounting bracket.
7. Check whether the inverter is securely in place.
If the Connection Unit can be moved forward, the lugs on the rear side of the Connection Unit
are not hooked into the lower recesses in the wall mounting bracket. Remove the inverter from
the wall mounting bracket and hook it in again.
Once the Connection Unit cannot be moved forward, the inverter is securely in place.
8. Secure the inverter to the wall mounting bracket.
To do this, guide the screw M5x60 through the
hole on the left side of the Power Unit using a
Torx screwdriver (TX 25) and screw it into the
thread (torque: 1.7 Nm ± 0.3 Nm (15.05 in-lb
± 2.65 in-lb).
9. If the inverter is to be protected against theft, attach a padlock:
• To do this, guide the shackle of the padlock
through the provided hole on the left side of
the Power Unit and close the shackle.
• Keep the key of the padlock in a safe place.
