  • Ground Mounting Set (Vaisala item OPTMSET2)

    • Mounting stand (delivered in three parts)
    • Wedge anchors (6 pcs) for securing the mounting stand to ground
    • Screws, washers, and nuts
  • 6-mm Allen key
  • 13-mm wrench
  • Impact drill and bits
Use the Ground Mounting Set when a free standing installation of the DGA monitor is needed. The mounting surface must allow the use of wedge anchors to secure the mounting stand. A concrete surface that is at least 100 mm thick is recommended.
Figure 1. Assembly of the mounting stand
Mounting holes on the top are for attaching the DGA monitor.
Mounting holes on the side join the parts of the mounting stand together.
Holes on the bottom (three on each side) are for anchoring the mounting stand to the ground.
Attach the power supply unit to the middle part using these four holes.
  1. Assemble the mounting stand. Tighten the screws to finger tightness at this point, not all the way.
  2. Using the assembled mounting stand as the template, mark the locations of the six anchors on the mounting surface. If the mounting location is at the edge of a concrete slab, leave at least 10 cm (4 in) clearance to the edge.

  5. Attach the mounting stand to the anchors.
  6. Verify that the mounting stand is securely anchored.
