Installing the Mounting Bracket

Installing the Mounting Bracket

Prerequisites

NOTE:
  • When installing the SUN2000-29.9KTL/33KTL-A/36KTL, you can use the expansion bolts delivered with the SUN2000 to install the mounting bracket.
  • When installing the SUN2000-42KTL, you need to prepare the expansion bolts. M12x60 stainless expansion bolts are recommended.

Context

Figure 4-9 shows the SUN2000 mounting bracket dimensions.
Figure 4-9  Mounting bracket dimensions
NOTE:

The SUN2000 mounting bracket has 16 tapped holes in four groups. Mark any hole in each group based on site requirements and mark four holes in total. Two round holes are preferred.

Procedure

  1. Remove the security torx wrench from the mounting bracket and set it aside.

    Figure 4-10  Removing a security torx wrench

  2. Determine the positions for drilling holes using the mounting bracket available in the packing case. Level the hole positions using a level, and mark the hole positions using a marker.

    Figure 4-11  Determining hole positions

  3. Drill holes using a hammer drill and install expansion bolts.

    Avoid drilling holes in the water pipes and power cables buried in the wall.

    An expansion bolt contains four parts, as shown in Figure 4-12.

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

    1. Put a hammer drill with a Ф16 mm drill bit on a marked hole position perpendicularly against the wall and drill holes to a depth of 52–60 mm.
    2. Slightly tighten an expansion bolt, vertically insert it into the hole, and knock the expansion bolt completely into the hole by using a rubber mallet.
    3. Partially tighten the expansion bolt.
    4. Remove the bolt, spring washer, and flat washer by rotating them counterclockwise.
  4. Align the mounting bracket with the holes, insert expansion bolts into the holes through the mounting bracket, and tighten the expansion bolts to a torque of 45 N·m using an 18 mm socket wrench.
