RJ, RJ, RA, RA, RJ, RA9A, RAA INSALLAION MOUNING For replacement, mount the relay in the same location as the old control. If this is a new installation, locate the relay vertically on a solid wall or partition as near as possible to the device to be controlled. Select a location that is easily accessible for installation and service. NOE: o reduce possible transformer hum and relay noise that can be amplified by mounting surfaces of sheetmetal, plasterboard, and similar materials, place rubber or felt washers between the case and the mounting surface. l. Position the relay and mark the mounting holes. See Fig... Start a screw for the keyhole type mounting hole in the upper right-hand corner. urn down screw within about l/ in. [. mm] of the surface.. Hang the relay on the screw, position the case, and start the bottom screw.. ighten both screws. IMPORAN: he switching relay terminals are approved for use with copper wires only. All wiring must comply with all applicable electrical codes, ordinances, and regulations. Follow any instructions furnished with the controlled equipment. See Figs through 0 for hookup diagrams for these relays. When two or more devices are to be controlled in parallel, the total current must not exceed the relay load rating. Fig. is an internal view of the RAA, showing terminal locations and barriers. Never connect load terminals to a load that takes more current than the amount listed in the electrical ratings on the relay. See able for wiring length specifications.

Keep the cover on the relay during normal operation and remove only for service and checkout.. Relay contacts require no cleaning; contacts close with a wiping action and are self-cleaning. hey may turn black after being in service for some time; however, this discoloration does not prevent proper operation.. After installation is complete, operate system through at least one cycle from the controller to make certain the relay controls the equipment as intended. 6 N.O. N.C. COM. N.O. N.C. COM.
