Installation Notes:

the up arrow should not point below horizontal
do not solder to or bend connector tabs
avoid lateral forces and mechanical loads (overly stiff or tight wires)
do not rigid mount both ends of connector
limit mounting eccentricity (runout / wobble) to .005" (.13mm)
provide overload protection within the circuit
avoid vibration and bumping motions
