(2) Unless otherwise specified, all tests are under room temperature and humidity. (3) Consider the heat of PCB is necessary, please check the actual condition of PCB. (4) Do not use the relay exceeding the coil rating, contact rating and life expectancy, or this may cause the risk of overheating. (5) To assure optimum performance, avoid the relay from dropping, hitting, or other unnecessary shocks. (6) Straight cover version is recommended. If there is cleaning process and sealed type is selected, the vent-hole should be removed after the process. (7) Use suitable harnesses and bus bars according to the current as below 5A typeMin. 2.0 mm 2 (8) Usage, transport and storage conditions 1. Temperature: -25+70C 2. Humidity: 5 to 85% R.H. 3. Pressure: 86 to 106 kPa Furthermore, the humidity range varies with the temperature. So, use relays within the range indicated in the graph below.
