7.6.4 Relieving the cables and lines of strain
NOTE
Incorrectly implemented strain relief
Lack of strain relief or incorrectly implemented strain relief on cables and
lines in energy chains leads to damage. Cables and lines will be destroyed.
This results in operational failure.
• Relieve the strain on every cable and every line individually. Never bunch
together several cables and lines into one strain relief. (Exception: IGUS
Chainfix multi-clamps)
• For traverse paths of the energy chain that are less than 50 m:
Relieve the strain on the cables and lines on both the driver and fixed side.
(Exception: Lines which extend under pressure e.g. hydraulic or pneumatic
lines must only be relieved of strain on the driver side)
• For traverse paths of the energy chain longer than 50 m:
Relieve the strain on the cables and lines on the driver side.
NOTE
Protruding strain relief
The energy chain becomes hooked in if metal sleeves and protruding strain
relief are used. The energy chain can break or become prematurely worn!
• Do not install strain relief at a higher level than the connection element
• Remove the metal sleeves on the upper side of the connection element
NOTE
Damage to the sheaths of the cables
Cable fittings which are too tight damage the sheaths of the cables.
• Do not tighten the cable fittings too firmly.
NOTE
Excessively high tightening torques
Special cables such as FOC (fiber optic cables) or similar can be destroyed by
the torque of 1 Nm at ChainFix strain reliefs!
• It is essential to comply with the cable specifications
• Consult with the manufacturer of the energy chain
