Wall-mounted Installation

Procedure

1. Determine the installation positions for drilling holes, and mark the positions using a marker.
2. Secure the mounting brackets.
   • 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.

   Avoid drilling holes in the utility pipes or cables attached to the back of the wall.

   • To prevent dust inhalation or contact with eyes, wear safety goggles and an anti-dust respirator when drilling holes.
   • Clean up any dust in and around the holes using a vacuum cleaner and measure the distance between holes. If large hole tolerance exists, position and drill holes again.
   • After removing the bolt, spring washer, and flat washer, level the front of the expansion tube with the concrete wall. Otherwise, the mounting brackets will not stay steady on the concrete wall.
   • Partially loosen the nut, flat washer and spring washer of the two expansion bolts below.

5. (Optional) Install the anti-theft lock.
   • Prepare an anti-theft lock suitable for the lock hole diameter (Ф8 mm) by yourself.
   • An outdoor waterproof lock is recommended.
   • Keep the key to the anti-theft lock safe.
