2.2Decide on Placement of the OpenComms EM

The unit may either be placed on a level surface or mounted on a wall, depending on the user’s appli- cation and the location of equipment to be connected and monitored. vEM-14 controllers may also be mounted in a rack.

•If placing the unit on a level surface, such as a shelf or a desk, proceed to 2.3 - Make Connec- tions.

•For wall or rack mounting, see the appropriate section for your model:

•2.2.1 - Mounting the Unit on a Wall (EM / EM PDU Controllers)

or

•2.2.2 - Mounting the Unit on a Wall or in a Rack (vEM-14 Controllers)

2.2.1Mounting the Unit on a Wall (EM / EM PDU Controllers)

The bottom of the EM / EM PDU controller has two holes to accommodate screws to secure the unit to a wall, either horizontally or vertically. You will need a screwdriver and any screws or bolts that will fit in the slots on the bottom of the unit.

1.Mark the wall for the mounting holes 1-3/4" (44.5mm) apart (see Figure 4).

2.Drill holes, if required, to install the two screws that will secure the unit to the wall. Clean up the debris.

3.If the wall material is not strong enough to hold the screws securely, use wall anchors.

4.Install the two screws—the screw heads must be small enough to slip through the larger, bottom portion of the mounting slot in the OpenComms EM (see Figure 4). The screws must also be large enough to extend over the edges of the top of the mounting slot.

5.Tighten the screws until they will hold the OpenComms EM tightly to the wall.

6.Hang the OpenComms EM on the screws, pushing the unit down until the screws are in the smaller, upper portion of the slot.

7.Proceed to 2.3 - Make Connections.
