3.Application Notes:
3.1. 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 time 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.
3.2 Suggestions of relay’s output
(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.
