how to install Middle Atlantic Proximity PRX-WB-22X14-NP

Installing the PRX-WB-22X14-NP involves planning a suitable wall placement, preparing the wall cavity, and aligning the in-wall box for a clean, flush finish. Begin by identifying a suitable wall location that accommodates the box’s 22.25" x 14.25" footprint and provides access for PDU connections, cabling, and service. Ensure that the selected location allows for proper ventilation and meets any applicable building and safety codes. Once the site is prepared, you can install the in-wall box securely within the wall cavity using the provided mounting provisions and ensure it sits plumb and square. The included trim ring then can be attached to achieve the desired depth, within the 3.7"–4.2" range, so the front face aligns with the wall surface for a seamless, professional appearance. After mounting the box, route power and communication cables as required, place the PDU and any necessary adapters or connectors inside the enclosure, and then complete the installation by attaching any faceplates, covers, or service panels that accompany your Proximity configuration. Finally, verify that all connections are secure, the PDU operates correctly, and that the finished installation presents a tidy, professional front with no visible wiring behind the wall.
