**Safety Precautions** - Turn off the power to the RJ relay before starting installation, removal, wiring, maintenance, and inspection. Failure to turn power off may cause electrical shock or fire hazard. - Use wires of the proper size to meet the voltage and current requirements. - Tighten terminal screws to a proper tightening torque. - Observe the specifications and rated values, otherwise electrical shock or fire hazard may be caused.
