Plan the route before installation
Mark the cable route, identify moving equipment, hot surfaces, sharp edges and areas exposed to oil or water. Select a polyamide grade whose temperature and chemical-resistance range matches the site. Confirm conduit diameter from the cable bundle and applicable fill requirements.
Prepare the conduit and cable
Cut the conduit squarely with a suitable tool and remove loose material. Do not crush the corrugations. Inspect every cable for jacket damage and group conductors according to the panel drawings. Where power and signal cables require separation, maintain the specified distance throughout the route.
Install fittings correctly
Use fittings designed for the selected conduit series and size. Push or thread the conduit fully into the fitting, verify the locking mechanism and fit sealing washers where required. The enclosure entry must be clean, correctly sized and free of burrs.
Route and support
Maintain the minimum bend radius and avoid pulling the conduit tight between two fixed points. Provide supports close enough to prevent sagging, but allow controlled movement near machine doors and actuators. Protect the run from direct impact and do not place it against hot components.
Test and document
- Check continuity, insulation and protective bonding as applicable.
- Confirm that every gland and fitting is fully engaged.
- Verify movement through the complete machine cycle.
- Label both ends and update the cable schedule.
- Record the conduit type and size for future maintenance.
A disciplined installation protects the cable, simplifies maintenance and reduces unplanned downtime.
