Danger to life due to high voltages
• Disconnect the inverter from all voltage sources (see Section 3, page 5).
2. Hook the new Power Unit into the upper recesses of the wall mounting bracket, thus plugging
the Power Unit into the Connection Unit. Make sure that the screw holes on the left and right
sides of the Power Unit are directly over those of the Connection Unit.
3. Fasten two screws with washers on the right and left side of the Power Unit using a Torx
screwdriver (TX 25) (torque: 6 Nm ± 0.3 Nm (53 in-lb ± 2.65 in-lb)).
4. Secure the inverter to the wall mounting bracket.
To 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 (15.05 in-lb
± 2.65 in-lb)).
5. 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.
6. Pull the ribbon cable used to connect the
communication assembly to the Power Unit out
of the Power Unit through the opening COM
into the Connection Unit, and plug it into the jack
on the communication assembly.
