Typically, these numbers are directly labeled next to or above the terminals of the relay. 3.Pay attention to polarity and orientation: During installation, ensure it’s placed correctly. This includes aligning the polarity properly and installing according to the direction indicated on the wiring diagram. Especially when installing multiple relays in parallel, ensuring a spacing of 2mm between them can effectively reduce heating and affect the operating voltage. 4.Wiring test: After installing the relay, perform a wiring test to ensure everything is functioning correctly.
