Installation & Handling Guidelines
Pre-installation
-
Inspect the cable for any visible damage to the rubber sheath
-
Avoid dragging on sharp edges – protect the cable during pulling
-
Use proper cable grips – never pull by the sheath alone
Temperature Considerations
-
Minimum installation temperature: -25°C (standard version)
-
For temperatures below -25°C, use the enhanced version rated to -40°C
-
Pre-heat the cable if ambient temperature is extremely low to prevent sheath cracking
Termination
-
Use appropriate connectors for fine-stranded Class 5 conductors
-
Avoid screw terminals without pin terminals – use open-type lugs or pin ferrule
-
Follow torque specifications to prevent loosening from vibration
Testing After Installation
-
Insulation resistance test – measure between cores and between core/earth
-
Continuity test – verify protective conductor integrity (GNYE core)
-
High voltage test – 2500V AC for 5 minutes (per EN 50525-2-21)
