CAUTION

Risk of injury due to weight of product

Injuries may result if the product is lifted incorrectly or dropped while being transported or mounted.

  1. Transport and lift the product carefully. Take the weight of the product into account.
  2. Wear suitable personal protective equipment for all work on the product.

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 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. CAUTION

    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.

    1. 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.

  7. 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.
  8. Check whether the inverter is securely in place.
  9. 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.

  10. 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 tighten it (TX25, torque: 1.7 Nm ± 0.3 Nm).
  11. 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.
