This power Relay uses high-amperage-capacity contacts to transfer power to large fans, pumps or lighting systems that require high voltage or amperage service. Prevents premature failure of equipment due to excessive current draw. Allows switching of 240-volt equipment with 120-volt controls. Prevents equipment overheating due to insufficient power supply. Provides 30-amp switching capacity with 120-volt trigger input from control device. Approved for indoor use only. This equipment must be installed by qualified service personnel.
How To Operate
Make certain power is disconnected at main breaker or service panel. Remove "Power In" junction box cover and slip power wire through wire clamp. Connect power wire from service to leads in junction box on "Power In" side of HAR-1 relay using wire nuts provided. Assure that wire nuts are twisted tightly and no bare wire is exposed. Attach power lead from equipment to the "Power Out" side in the same fashion and replace cover plates. Re-establish power from service and plug switching trigger pigtail into control device. Turn "On" power switch and unit is ready to operate.
