Cable Details
The mating connectors for the FT702LT are suitable for use with cables with overall diameters of up to 9mm
and for individual cores of diameters of up to 1.2mm. Cable such as SD980CPTP 3x2x0.5mm2 from SAB
Brockskes or similar types may be used. Care must be taken to ensure that the cable is suitable for the
environment it will be used in and is adequately approved, for example AWM Style 21198.
In an area with a moderate or severe lightning strike exposure the cable shield will not provide sufficient
protection. In this case the cable will require further shielding such as being enclosed in a metal pipe or conduit
(see section 3.3).
