with the applicable connection diagram located in instruction book
MN01301001E (NF) and MN01301003E (RF). Leads are also supplied
with keyed secondary connector plugs to ensure proper connections
(Figure 30).

can be removed by squeezing two release tabs together with small
needle nose pliers and pulling out (Figure 31).
