RA832A Switching Relays<br />
INSTALLATION INSTRUCTIONS<br />
These relays can be used for a variety of switching applications. Typically they provide control of line- or low-voltage<br />
devices by a low voltage controller. See Table 1.<br />

a IMPORTANT:<br />
The transformer on the R182 can overheat<br />
when used with a series 20 thermostat if the<br />
total resistance of the thermostat circuit<br />
exceeds 2.5 ohms. If the measured resistance<br />
of the thermostat (including thermostat wire and<br />
thermostat contact resistance) exceeds 2.5<br />
ohms, add a 100 ohm, 10 watt resistor between<br />
the W and R terminals. Table 2 gives maximum<br />
thermostat wire runs; if longer runs are necessary,<br />
measure the resistance or add a 100 ohm,<br />
10 watt resistor across terminals W and R.<br />

INSTALLATION<br />
When Installing this Product<br />
1. Read these instructions carefully. Failure to follow<br />
instructions can damage product or cause a hazardous<br />
condition.<br />
2. Check the ratings given in the instructions and on<br />
the product to make sure the product is suitable for<br />
your application.<br />
3. Make sure installer is a trained, experienced service<br />
technician.<br />
4. After <strong>com</strong>pleting installation, use these instructions<br />
to check out product operation.<br />
WARNING<br />
Electrocution Hazard.<br />
Can cause property damage, severe injury, or<br />
death.<br />
Transformer core not bonded.<br />
Disconnect power supply before wiring to prevent<br />
electrical shock or equipment damage.<br />
Mounting<br />
For replacement, mount the relay in the same location as<br />
the old relay. If this is a new installation, locate the relay<br />
vertically on a solid wall or partition as close as possible to<br />
the device to be controlled. Select a location that is easily<br />
accessible for installation and service.<br />
NOTE:<br />
To reduce the possible transformer hum and<br />
relay noise that is sometimes amplified by<br />
mounting surfaces such as sheet metal, plasterboard,<br />
and similar materials, place rubber or felt<br />
washers between the case and the mounting<br />
surface.<br />
1. Position the relay and mark the mounting holes.<br />
See Fig. 1.<br />
2. Start a screw for the keyhole type mounting hole in<br />
the upper right corner. Screw it down within about 1/<br />
8 in. (3 mm) of the surface.<br />
3. Hang the relay on the screw, position the case, and<br />
start the bottom screw.<br />
4. Tighten both screws.<br />
Wiring<br />
All wiring must <strong>com</strong>ply with all applicable electrical codes,<br />
ordinances, and regulations. Follow any instructions<br />
furnished with the controlled equipment.<br />

TO LOAD<br />
See Fig. 2 through 9 for hookup diagrams for these<br />
relays. When two or more devices are to be controlled in<br />
parallel, the total current must not exceed the relay load<br />
rating. Fig. 10 is an internal view of the RA832A showing<br />
terminal locations and barriers.<br />
Never connect load terminals to a load that takes more<br />
current than the amount listed in the electrical ratings on<br />
the relay.<br />

SERVICE AND CHECKOUT<br />
M3824A<br />
1. Never use oil on any part of the relay coil or contacts.<br />
2. Keep the cover on the relay during normal operation<br />
and remove only for service and checkout.<br />
3. Relay contacts require no cleaning; they are<br />
arranged so they close with a wiping action and are<br />
self-cleaning. The contacts may turn black after<br />
being in service for some time; this discoloration<br />
does not prevent proper operation.<br />
4. After installation is <strong>com</strong>plete, operate system<br />
through at least one cycle from the controller to<br />
make certain the relay controls the equipment as<br />
intended.<br />
