Cautions of Latching Relay:
1.Suggestions of relay's input
(1)Polarity-Please check the polarity inside of our technical specification, if single coil then"+ -" or "- +"are fine,
you can change it by one pulse.If double coil then it's necessary to confirm "-+-" or "+-+"before leaving the our factory.
(2)Driving-Please energize the relay at our recommend pulse width, rated voltage for reliable performance, if 1.5
times or 2 times of value or lower driving condition plz confirm with our engineer.
(3)Relays'contact status may be changed during transportation or installation due to impact of external force,
therefore please reset to the required status.

(1)When choosing the relay with hard connection,please avoid the external force on load terminals during or after
(1)When choosing the relay with hard connection,please avoid the external force on load terminals during or after
the installation.
(2)When the relay will be connected with screw or bolts to the relays' terminals, plz make sure your connection is
fastened and prevent relay from damages or other safety problems due to temp. Rise..
(3)The sampling signal wires of products are limited, please do not pull or torque during installation.
