5.2 Cables and wires
Only use cables whose diameters are permissible for the respective cable gland. The
cables must meet the requirements and wire cross-sections specified in the tech-
nical data.
The connected cables must be suitable for a temperature which is at least 10°C
above the maximum permissible ambient temperature.
•
Carry out the line connection with special care.
•
The connecting cable and its installation must comply with the applicable
regulations.
•
When laying the cables, make sure that mechanical damage to the conduc-
tor insulation on sharp-edged or moving metal parts is excluded.
•
Use the Berthold approved cable or a cable with equivalent specifications
for connection.
Lay the connecting cables in such a way that
•
no dirt or moisture gets into the terminal compartment,
•
the conductors are not damaged during stripping,
•
the conductor insulation or the collar of the ferrule extends into the housing
of the terminal body,
•
bare conductive parts of the cables (e.g. wires of a stranded wire) do not
protrude from the terminal body,
•
the length of the ferrule or stripped wire is 8 mm so that the wire is held
securely in the clamp,
•
all strands are pressed with a ferrule,
•
the conductor insulation extends into the collar of the ferrule,
•
the minimum permissible bending radii for the respective conductor cross-
section are not undershot,
•
the cables are strain-relieved and installed without abrasion.
Cable glands and dummy plugs
•
Cables may only be fed into the wall housing via a cable entry.
•
The screw connections must be suitable for the respective application.
•
All cable glands must be fitted according to the manufacturer's instructions
and tightened to the appropriate tightening torque (cable gland M20 =
5.5 Nm).
•
The feedthroughs not required for installation must be closed with suitable
dummy plugs.
•
The permissible cable cross-section must be matched to the cable used.
•
The cable conduits and dummy plugs must be designed to meet the appli-
cable protection level requirements or the requirements of the operating
environment.
•
We recommend ordering missing fittings, dummy plugs or adapters from
Berthold.
