3.7 Cables
3.7.1 Manufacturing
If you do not use the cables delivered by ETEL, follow the shield recommendations below for those cables:
• The encoder cables: JC5 and / or JC6.
• The motor cable: JC7.
• The inputs/outputs cables: JC9 and / or JC10.
Simple shielded cable must be linked to the connector shells on both cable ends. Only full metallic conductive
shells connector must be used. Shield with only aluminum foil (metallized plastic film) is forbidden!. Use only
copper braid (85% covering shield). The shield must entirely cover all wires. 'Pig tails' connections are
forbidden! The shield contact on 360° and a metallic cable clamp is necessary.
Remark: All the cables connected to the controller must have copper conductors only and an insulation
standing at least 75°C.

Here is an example of good shielding connection:
Here are two examples of bad shielding connections:
