Notes2. The product storage location shall not be exposed to corrosive gas. Avoid direct sunlight on the products.
1.The relay is a high-voltage DC switching device. In the final fault state, it may not be able to connect or cut off. Once the product cannot be cut off, may lead to abnormal heat and smoke, fire or other accidents. Therefore, please avoid the use of the above specifications
(including but not limited to coil rating, load ratings and electrical life, etc.) . Please use a circuit that can quickly cut off the load in an emergency. To ensure safety, the product should be replaced regularly.
2.The terminals of the relay has the polarity difference, so be sure to make the correct connection according to the label on the surface of the product. The electrical characteristics promised in this specification will not be guaranteed if the terminals are connected to
the opposite direction.
3.When the relay is used in the charging circuit, the pre-charging circuit should be added to ensure that the impact current is kept belowthe rated load current of therelay. As shown in the following figure, the charging time sequence is: firstly switch on the main negative relay, then switch on the pre-filled relay, and finally switch on the main positive relay. If there is no pre-charging circuit, a transient large current will be generated at the moment of the main relay conduction, which will cause the contact bonding of the relay to be unable tobe cut off. Please pay attention to it.
4.Contacts rating is the value under resistive load. Please take measures of surge absorption device together with inductive load when using the L/R≥ 1ms inductive load (L load), otherwise it may lead to the decrease of electrical endurance and defective switch.
5. It is recommended to install the nonlinear resistance (recommend using variable resistance) in order to suppress the reverse electromotiv force of coil. But please do not use diode, otherwise it will lead to the decline of relay performance.
6. It is strictly prohibited to place the relay for a long time in the environment beyond the operating temperature (-40~85℃) of the product.
7.Please do not install the product in a strong magnetic field (the periphery of a transformer, or magnet) or near the heating object.
8. In order to prevent looseness, please use the gaskets correctly when installing the relay. Please use M5 screws to install therelay, the locking torque should be controlled within 3N.m ~ 4N.m . The locking torque of M6 mounting screws on the terminals should be controlled within 5N.m ~ 6N.m . During and after the installation of the load-terminal screws, the axial torque borne by the load terminals should be less than 1 N.m . The product may be damaged in the case of excessive torque.
9.Please avoid grease and other foreign matter attached to the terminals. Please use the connection wire above 60mm2 spec, otherwise it may lead to abnormal heating of the terminals.
10.Please use the specified connector when connecting to the connector.11. In principle, please do not use it when therelay has fallen down.
