Mounting the New Power Unit
1.
Danger to life due to high voltages
• Disconnect the inverter from voltage sources (see inverter manual).
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; and the cables
protruding from the Power Unit must not be pinched.
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 into the
Connection Unit, and plug it into the jack on the
communication assembly.
