After determining where to place the unit, check to ensure that you have all the hardware required to install the unit in a rack.

Obtain the needed tools and material. You will need these items for wall or rack mounting:

Brackets for rack mounting - 2 (provided)

Screws to attach brackets - 4 (provided)

Phillips screwdriver

Follow the instructions below for either Wall Mounting or Rack Mounting.

Wall Mounting

The vEM-14 controller has four holes on each side to accommodate various ways of attaching the brackets (see Figure 5).

The brackets can be installed facing up or down for wall mounting.

1.Mark the wall for the mounting holes 1-3/4" (44.5mm) apart (see Figure 5).

2.Drill holes, if required, to install the 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 screws and tighten until they will hold the brackets tightly to the wall.

5.Hang the unit on the brackets.

6.Proceed to 2.3 - Make Connections.

Rack Mounting

The vEM-14 controller has four holes on each side to accommodate various ways of attaching the brackets (see Figure 5). The unit may be front- or rear-mounted, and it can fit into a 19" or 23" rack.

The brackets can be installed facing forward or toward the rear for rack mounting.

1.Decide whether the unit will be front- or rear-mounted. Use the longer side of the bracket for a 19" rack; use the shorter side of the bracket for a 23" rack:

2.Attach the bracket using two screws at front of unit for front mounting. For rear mounting, use holes at rear of unit. Attach the second bracket on the other side.

3.Slide the unit into the rack and secure the brackets to the frame (mounting hardware not included).

4.Proceed to 2.3 - Make Connections.
