proper direction, paying attention to the (+) and (-) ends.
2-6. Tuck the wires connected to the SE terminal block neatly
between the batteries and pull the excess wire back
through the strain relief.
Re-seat the PCB in the case, and securely tighten the
cable fitting.
2-7. Set the Termination Type switch to either 10K or DC.
(see Appendix) This selection must match the
Termination Type in the Safety Edge.
