Notes:

1.Exciting cable is a 3-wire chloroprene sheathed cable. For a nominal cross- sectional area of 1.25 mm², the overall diameter will be 12 mm (15/32 inch): for 2 mm², 13 mm(1/2 inch).

2.Signal cable is a 2-wire shielded chloroprene sheathed cable with a nominal cross-sectional area of 0.75 mm² and an overall diameter of 12 mm (15/32 inch).

3.Relation between exciting cable length and its nominal cross-sectional area and overall diameter is as follows.
