PAGE 3
NOsparc User Manual Page 3 of 6 CAUTIONS The NOsparc will pass a leakage current (see specifications) even though the contacts across which it is connected are open (similar to leakage present with snubber use). This capacitive leakage current can be sufficient to turn-on some solid state and electromechanical relays, or to cause electric shock to personnel. Therefore: – The NOsparc must never be connected across relay, contactor, or snap action switch contacts driving high impedance loads.

NOsparc Wiring Diagram In order to provide effective arc suppression, the two wires between NOsparc arc suppressor and the relay, contactor, or snap action switch contact terminals should be as short as possible. One foot or less of wire length is ideal; lengths over 3 feet are not recommended.
