4.1
Cables
The sensor cables must not be laid out directly side by side with other unshielded lines potentially
emitting strong electromagnetical interference radiation.
Such lines are e.g. servo motor cables or other cables carrying large pulsed currents.
In case of very strong interference sources the same applies also for the SND40 power supply
cable and signal cable towards the control unit.
In order to reduce interferences, laying out the SND40 cables within separate EMC cable channels
might be required.
All cables must be professionally laid out. Bending radii (see suppliers data sheets) must be kept
to. Damages due to wearing / buckling must be avoided by circumspective installing.
Note:
Care for sufficient strain relief!
Damaged cables may never be used, they need to be replaced immediately.
If the cables cannot be used (e.g. due to missing UL/CSA permission), contact Roland Electronic
for substitutes.
The provided snap-on cores are designated for a preventive protection from HF-interferences.
These can be simply snapped on the connected cables.
