2. Drill holes at the marked positions using a hammer drill and install expansion
bolts.
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 a
dust mask when drilling holes.
– Use a vacuum cleaner to clean up dust in and around the holes, and
measure the spacing. If the holes are inaccurately positioned, drill the holes
again in correct positions.
– Partially tighten the expansion bolts, and then remove the hexagonal bolts
and at washers from the expansion bolts.

Step 2 (Optional) Install a DC switch padlock.
● For models used in Australia, the DC switch padlock needs to be installed according to
the local standard to secure the DC switch (DC SWITCH) and prevent incorrect startup.
● The DC switch padlock needs to be prepared by the customer. Select a padlock based on
the lock hole diameter (Ф6 mm) to ensure that the padlock can be installed smoothly.
● An outdoor waterproof padlock is recommended.
● Keep the padlock key properly.
