position. (See “Figure A-5Gradiometer sensor cabling” on page A2-7.)

Attach
the upper sensor to the lower one by placing the shaft of the
lower sensor into the socket of the upper one while rotating slightly
counter-clockwise . When they are fully engaged, firmly twist them
clockwise against each other.
Warning:
Both sensors must have their directional marks aligned in the same
manner, i.e. the N on the top sensor must be in-line with the N on the
bottom sensor.

Remove
the cable hold-down plate of the upper sensor by unscrewing
the screws at the 2 o’clock and 4 o’clock positions.
15.
Connect
the white wire of the two-conductor cable coming from the
lower sensor to the terminal at the 1 o’clock position.
16.
Connect
the bare wire of the two-conductor cable coming from the
lower sensor to the terminal at the 11 o’clock position.
