Risk of injury when lifting the inverter, or if it is dropped
The inverter weighs 26 kg (57.32 lbs). There is risk of injury if the inverter is lifted incorrectly or
dropped while being transported or when attaching it to or removing it from the wall mounting
bracket.
• Transport and lift the inverter carefully.
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.
