KRE-2: Metal Enclosure

The KRE-2 Metal Enclosure

The KRE-2 Metal Enclosure is intended to provide a secure enclosure for the PXL-250 controller.
A lock on the enclosure cover ensures that only authorized hands have access to the controller (two
keys are provided). Twelve knockouts are spaced around the body of the enclosure providing
maximum flexibility for routing cabling into the controller. The enclosure is mounted to any solid
surface using four screws.

NOTE: The KRE-2 enclosure is not a sealed, weatherproof enclosure. It is not meant for use in
extreme environmental conditions.

2.0 Enclosure Mounting

The easiest method for marking the location of the mounting holes for drilling is to hold the
enclosure against the mounting surface and then use a pencil to mark the mounting hole locations
against the surface to which the enclosure is to be mounted. If this is not practical, Figure 2 is a
layout drawing of the mounting hole locations.

NOTE: Figure 2 provides the measurements for the mounting hole locations. Figure 2 is not an
actual size drawing and cannot be used as a drilling template.

4.0 Controller Mounting

The PXL-250 controller is shipped in plastic, hinged-lid enclosure. Open the lid and use a
screwdriver to remove the controller from the plastic enclosure. Save the screws for controller
mounting in KRE-2.

Once the enclosure is mounted and the cabling is routed to the enclosure, the controller is mounted
into the enclosure (see Figure 4). There are four standoffs in the back of the enclosure to which the
controller is mounted. Use the four screws provided with the plastic enclosure to mount the
controller in the KRE-2. Simply align the controller over the four standoffs and insert the screws.

NOTE: Do not over-tighten the mounting screws as this can damage the controller.
