Notes for application:

A1 + terminal is input (in);A2 terminal is output (out);See the real product for details

At the end of relay life, i.e. when the DC voltage of the insulation meter is 500V, the insulation strength between the leading out load terminals is lower than 50 megohm (insulation resistance)

(1) Do not touch the load terminal when the relay is powered on to avoid electric shock

(2) When the control circuit and non-metallic materials are subjected to withstand voltage test, the load voltage shall be disconnected

(3) Avoid installing the product in a place with strong magnetic field (transformer or magnet) or close to objects with thermal radiation

(4) Don't touch the foreign matters and oil stains on the main lead-out terminal, and the external lead-in wire terminal and the main lead-out terminal are in reliable contact, otherwise the terminal will be heated severely and the connecting cable will be melted

(5) In the action voltage test, do not make the voltage rise slowly, please drive the coil by step power supply

(6) The bolt locking torque of each installation part shall be controlled within the specified range.The locking torque of the nut at the load installation position is 2n. M;The torque of the stud at the relay mounting position is 4-5n. M

(7) In principle, please do not use it when it falls outside the relay and is impacted
