3. User Manual When using NOsparc MMYac basic safety precautions should always be followed to reduce risk of fire electric shock and injury to persons When installing NOsparc MMYac into your system make sure that the Quick Connect Terminal connector is properly crimped terminated insulated and that the proper wire gauge is used and that the connector is securely seated Incorrect application or termination can result in harmful or fatal electrical shock or component damage CAUTIONS Just like a snubber the NOsparc MMYac will pass a small leakage current see specifications even though h the contacts across which it is connected are open This capacitive leakage current can be sufficient to turn on some solid state and electromechanical relays or to cause electric shock to personnel Therefore e The NOsparc MMYac or a snubber must never be connected across relay or contactor contacts driving high impedance loads e The NOsparc MMYac or a snubber must never be connected across relay or contactor contacts used for galvanic safety isolation Proper care must be taken when handling and installing NOsparc MMYac Never plug or unplug NOsparc MMYac while powered Do not connect NOsparc MMYac directly to power Use caution when installing or modifying power connections Soldering wires directly to board mounted NOsparc MMYac terminals is not recommended For product evaluation please use the NOsparc MMXac which is
