High Density Terminals (HD Terminals) with 16 terminal points
The conductors of the HD Terminals are connected without tools for single-wire conductors using the direct
plug-in technique, i.e. after stripping the wire is simply plugged into the terminal point. The cables are
released, as usual, using the contact release with the aid of a screwdriver. See the following table for the
suitable wire size width.
Terminal housing
High Density Housing
Wire size width (single core wires)
0.08 ... 1.5 mm
2
Wire size width (fine-wire conductors)
0.25 ... 1.5 mm
2
Wire size width (conductors with a wire end sleeve)
0.14 ... 0.75 mm
2
Wire size width (ultrasonically “bonded" conductors)
only 1.5 mm
2
Wire stripping length
8 ... 9 mm
3.6.3
Proper line connection
Always connect only one wire per terminal point.
When using fine-wire conductors it is recommended to connect them with wire end sleeves in order to
establish a safe, conductive connection.
In addition, make sure that the pin assignment is correct to prevent damage to the ELX terminals and the
connected devices.
3.6.4
Shielding and potential separation
Shielding
Encoder, analog sensors and actors should always be connected with shielded, twisted paired
wires.
CAUTION
Observe installation requirements in areas of potentially explosive atmospheres!
During installation, observe the requirements for cables, shielding and earth potential equalization in areas
of potentially explosive atmospheres according to IEC 60079-11, IEC 60079-14 and IEC 60079-25.
WARNING
Ensure potential separation of the 24 V Ex busbar!
In any case, make sure that the galvanic isolation made by the ELX9560 between the 24 V Ex busbar
(power co24 V Ex and 0 V Ex) and other system potentials (if applicable also functional or protec-
tive earths) is not removed.
