Note: The cable braiding is folded back over the outer insulation of the motor cable to give a
larger diameter contact area and a mechanically strong fixing.
If you have a ready made ViX-PWR-XXXX cable, use the pre-fitted P-clip otherwise use one
of the clips listed below:

Table 3-4. P Clip sizes
Three different size P clips allow the use of a variety of motor power cables from different
manufactures.
All motor connections must be made using a high quality braided-screen cable. Cables
using a metallised plastic bandage for an earth screen are unsuitable and in fact provide
very little screening. Care must be taken when terminating the cable screen, the screen
itself is comparatively fragile; bending it round a tight radius can seriously affect the
screening performance. The selected cable must have a temperature rating which is
adequate for the expected operating temperature of the motor case.
