Mounting the SmartLogger on a Wall

Procedure

1. Install the expansion tubes and screws.

   If you need to use a ladder to install the SmartLogger on a high position, keep balance to protect yourself from falling down.

   1. Use a plumb line to ensure that the line between the centric points of the two holes is vertical to the ground. Use a marker to mark out the holes, as shown in Figure 3-3.
      Figure 3-3 Hole positions and dimensions
      

   2. Drill holes using a hammer drill and install expansion tubes and screws, as shown in Figure 3-4.

      Table 3-2 describes the operations shown in Figure 3-4.

      Step	Operation
      1	Put a hammer drill with a Ф6 drill bit on a marked hole position perpendicularly against the wall and drill holes with a depth of 24 mm to 25 mm. NOTICE: 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.
      2	Vertically insert an expansion tube into a hole, and knock it completely into the hole by using a rubber mallet.
      3	Insert the screws into the expansion tube until the screw heads are 7.5 mm to 8 mm away from the wall.

2. Hang the SmartLogger onto the secured screws by the mounting holes on the rear of the SmartLogger.

   Ensure that the area for connecting cables in the SmartLogger is downwards for the ease of electrical connections and maintenance.
