Chapter 2: Installing the system 9
CAUTION: Power cable
Using an incorrect size of power cable could reduce the power
supplied to the drive unit and therefore cause your SPX-5 Tiller
system to malfunction. Ensure the correct cable size is used. If in
doubt, use a heavier gauge cable.
The requirement for power cables depends on the total length of the power circuit.
That is the total length of Cable A + Cable B + Cable C.
The correct cable dimensions for various cable lengths are given in the following
table.
