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
