UL Requirements The Underwriters Laboratories (UL) requirements listed below pertain to the installation of the MLC into a wall or furniture. 1. Elevated operating ambient temperature — If the equipment is installed in a closed or multiunit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer. Fo

Installation, cont’d To prepare the site, 1. 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 or furniture before installing the controller. If using an electrical box to wall mount the controller, locate a stud to which the box will be attached. 2. Use the appropriate template and faceplate dimensions in appendix B, “Dimensions and Templates,” as a guide to measure and

IR learner/transmitter — These sensors allow for IR control of the MLC and 1 for IR learning. The two LEDs (one for transmitting, one for receiving) send and receive IR signals, enabling the MLC to learn commands and clone configurations from another MLC. The IR remote control must be pointed directly at these LEDs for best results. The MLC can “learn” IR commands in order to control the display device. IR learning of device control codes is necessary only if there are no RS-232 codes availab
