Introduction

3Attach the cables. See “Front panel features and cabling” and “Rear panel features and cabling” in the user’s manual specific to your product.

4Set the rear panel DIP switches. Use the “Rear panel features and cabling” section in the user’s manual specific to your product.

5Connect power cords and turn on the projector/ monitor and audio device, the interface, and the computer.

6The picture should now appear, and sound should be audible. If not, ensure that all devices are plugged in and receiving power. Check the cabling and the DIP switch settings, and make adjustments as needed.

7Disconnect power from all the devices.

8Mount the interface into the electrical box. See the sections on “Mounting the optional AAP device” and “Mounting the interface to the wall box” in this guide.

9Restore power to the devices.

UL Requirements

The following Underwriters Laboratories (UL) requirements listed pertain to the installation of the RGB 400xi series of interfaces into a wall or furniture.

1.These units are not to be connected to a centralized DC power source or used beyond their rated voltage range.

2.These units must be installed in UL listed junction boxes.

Preparing the site and installing the wall box

Choose a location that will allow cable runs without interference. Allow enough depth for both the wall box and the cables. You may need to install the cables into the wall, furniture, or conduits before installing the interface.

The installation must conform to national and local electrical codes and to the equipment’s size requirements. Actual- size cut-out templates are provided in appendix A of this manual.

Installation using a UL listed wall box (available from Extron) is recommended for most mounting options, but the included mud rings can be used instead. All wall boxes must be at least 2.50” deep.

Before using the mud rings, verify that the installation will conform to national and local electrical codes.

The RGB 460xi and RGB 472xi will install in a two-gang wall box, the RGB 464xi, RGB 474xi, RGB 468 Mxi, and RGB 478 Mxi will install in a three-gang wall box, and the RGB 460xi Dual, RGB 468xi, and RGB 478xi will install in a four-gang wall box.

The RGB 468xi and RGB 478xi faceplates accept up to four single height Extron Architectural Adapter Plates (AAPs) and the RGB 468 Mxi and RGB 478 Mxi faceplates accept up to four single height Extron mini-AAPs.

1a. If you are using a wall box, make a 100% size photocopy of the cut-out template that corresponds to the faceplate you are using, and cut out the center portion of it as indicated on the template.

3.These units must be installed with conduit in accordance with the National Electrical Code.

Installation Procedures

All of the interfaces can be mounted into a wall or furniture. Follow the instructions appropriate to the mounting option you have selected. Templates for optional faceplates are not detailed in this manual.
