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.

do this, insert 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 (15.06 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.
