The latch type relay should be initialised at the appointed position (set or reset position) when using, and should be energised or de-energised to the specified polarity to avoid wrong operations. 2. Ultrasonic cleaning is not recommended. Alcohol or chlorosene based solvents are acceptable as cleaning solvents. 3. Excessive stress on the relay cover is detrimental to reliable operation of the relay.
