The Connection Unit and Power Unit can be disconnected from one another
to make mounting easier
If the local conditions make it difficult to mount the entire inverter, you can disconnect the
Connection Unit and Power Unit from each other if the ambient temperature is at least 0°C
(32°F) and there is no frost. This way, you can transport each enclosure part and also attach
to the wall mounting bracket individually. Then, during assembly, both enclosure parts must be
joined again. A detailed description for how to disconnect the Connection Unit and Power
Unit from each other and to individually mount them to the wall mounting bracket can be
found on the Internet under www.SMA-Solar.com.
Procedure:
1.
Risk of injury due to damaged cables
There may be power cables or other supply lines (e.g. gas or water) routed in the wall.
• Ensure that no lines are laid in the wall which could be damaged when drilling holes.
2. Align the wall mounting bracket horizontally on the
wall and use it to mark the position of the drill holes.
Here, use at least one hole each, to the right and
left, and the hole at the bottom center.
3. Set the wall mounting bracket aside and drill the marked holes.
4. Insert screw anchors into the drill holes if the support surface requires them.
5. Secure the wall mounting bracket horizontally using screws and washers.
6. Hook the inverter into the wall mounting bracket.
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.
