Wall-Mounted Installation
Procedure
- Determine the positions for drilling holes using the marking-off template. Level the positions of mounting holes using a level, and mark the positions with a marker.
- Secure the mounting bracket.
When drilling holes, avoid the water pipes and power cables buried in the wall.
- M6x60 expansion bolts are delivered with the SUN2000. If the length and amount of the bolts do not meet installation requirements, prepare M6 stainless steel expansion bolts by yourself.
- The expansion bolts delivered with the inverter are used for solid concrete walls. For other types of walls, prepare bolts by yourself and ensure that the wall meets the load bearing requirements of the inverter.

- To prevent dust inhalation or contact with eyes, wear safety goggles and an dust mask when drilling holes.
- Wipe away any dust in or around the holes and measure the hole distances. If the holes are inaccurately positioned, drill holes again.
- Level the head of the expansion sleeve with the concrete wall after removing the nut, spring washer, and flat washer. Otherwise, the mounting bracket will not be securely installed on the wall.
- Loosen the nut, spring washer, and flat washer of the expansion bolt at the bottom.
