Table 2 gives maximum thermostat wire runs; if longer runs are necessary, measure the resistance or add a 100 ohm, 10 watt resistor across terminals W and R.

Position the relay and mark the mounting holes. See Fig. 1. 2. Start a screw for the keyhole type mounting hole in the upper right-hand corner. Turn down screw within about l/8 in. [3.2 mm] of the surface. 3. Hang the relay on the screw, position the case, and start the bottom screw. 4. Tighten both screws.

All wiring must comply with all applicable electrical codes, ordinances, and regulations. Follow any instructions furnished with the controlled equipment. See Figs 2 through 10 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. 11 is an internal view of the RA832A, 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 Table 3 for wiring length specifications.

Keep the cover on the relay during normal operation and remove only for service and checkout. 3. Relay contacts require no cleaning; contacts close with a wiping action and are self-cleaning. They may turn black after being in service for some time; however, this discoloration does not prevent proper operation. 4. After installation is complete, operate system through at least one cycle from the controller to make certain the relay controls the equipment as intended. R882J 2 1 3 4 5 3 3 N.O. N.C. COM.
